STORAGE AND DATA ANALYSIS FOR A TRAINING SYSTEM

FOR WELDING

BACKGROUND

The invention relates generally to welding and, more particularly, to a welding training system.

Welding is a process that is increasingly used in various industries and applications. Such processes can be automated in certain contexts, although there are still a large number of applications for manual welding operations. In both cases, such welding operations rely on a variety of equipment types to ensure that the supply of welding consumables (for example, wire feed, shielding gas, etc.) is provided to the weld in adequate quantities at the desired time.

In preparation for manual welding operations, welding operators can be trained using a welding training system. The welding training system can be designed to train welding operators with the proper techniques to perform various welding operations. Certain welding training systems can use various training methods. As can be seen, these training systems can be expensive to acquire and operate. Consequently, welding training institutions can only purchase a limited number of such training systems. Also, certain welding training systems may not adequately train welding operators to perform high-quality welds.

Trigger 70 provides a lead 71 to drive a signal to control circuitry 52 to indicate whether trigger switch 72 is in the open or closed position. Wire feeder 30, welding power source 28, computer 18, and / or data reporting device 26 can determine if there is continuity through welding torch 14 through a first lead of trigger 74 and a second trigger lead 76. The switch on the

IMPI

Trigger 72 electrically couples between the first lead of trigger 74 and the second lead of trigger 76. Continuity across the first lead of trigger 74 and the second lead of trigger 76 can be determined by applying a voltage across leads 74 and 76 , applying a current through conductors 74 and 76, measuring a resistance across conductors 74 and 76, and so on. In certain embodiments, portions of the first trigger lead 74 and / or portions of the second trigger lead 76 may be disposed within a connector of the welding torch 14. In addition, in certain embodiments, the arrangement of the switches and / or leads inside the welding torch 14 may be different from that illustrated in Figure 2.

The welding power source 28 can determine if it allows the welding energy to flow through the welding torch 14 based on whether there is continuity across conductors 74 and 76. For example, the welding power source 28 may allow the welding power to flow through the welding torch 14 as long as there is continuity across the conductors 74 and 76, and the welding power source 28 can block flow. of the welding power through welding torch 14 as long as there is an open circuit through conductors 74 and 76. In addition, wire feeder 30 can provide the weld wire to the welding torch 14 as long as there is continuity through conductors 74 and 76, and can block the supply of the welding wire to the welding torch 14 as long as there is an open circuit to through conductors 74 and 76. Furthermore, computer 18 may use continuity across leads 74 and 76 and / or trigger position 70 or trigger switch 72 to start and / or stop a welding training operation, a training simulation for welding, recording the data, and so on.

With trigger switch 72 in the open position, there is an open circuit through leads 74 and 76, therefore, the open position of trigger switch 72 blocks the flow of electrons between leads 74 and 76. Accordingly, the welding power source 28 can block the flow of welding energy through the welding torch 14 and the wire feeder 30 can block the supply of the welding wire to the welding torch 14. Pressing trigger 70 directs trigger switch 12. to the closed position where trigger switch 72 remains as long as trigger 70 is depressed. With trigger switch 72 in the closed position, there is continuity between trigger first lead 74 and lead 77 that electrically connects to trigger switch 72 and a training switch 78.

The training switch 78 is electrically coupled between the first trigger lead 74 and the second trigger lead 76. Furthermore, the training switch 78 is electrically controlled by the control circuitry 52 to either an open or a closed position. In certain embodiments, training switch 78 can be any suitable electrically controlled switch, such as a transistor, relay, etc. Control circuitry 52 can selectively control training switch 78 to the open or closed position. For example, although the welding training software of the welding training system 10 operates in a live arc mode, the control circuitry 52 may be configured to control the training switch 78 to the closed position to allow a welding arc live while trigger 70 is depressed. In contrast, although the welding training software of the welding training system 10 works in any mode other than arc current mode (for example, simulation, virtual reality, augmented reality, etc.), the circuitry of control 52

ΤΟυΤΟ MEXICANO DELA INDUSTRIAL PROPERTY can be configured to control training switch 78 to the open position to block a live arc (blocking the flow of electrons between conductors 74 and 76).

In certain modalities, training switch 78 may by default be in the open position, thereby establishing an open circuit through conductors 74 and 76. As can be seen, while the training switch 78 is in the open position, there will be an open circuit through leads 74 and 76 regardless of the position of trigger switch 72 (for example, the flow of electrons between leads 74 and 76). 76 is blocked by the open position of training switch 78). However, while the training switch 78 is controlled to the closed position, and the trigger switch 72 is in the closed position, the conductivity between conductors 74 and 76 is established (for example, the flow of electrons between conductors 74 and 76 is enabled). Accordingly, the welding power source 28 may allow the welding power to flow through the welding torch 14 only while the training switch 78 is in the closed position and while the trigger switch 72 is in the closed position. . For example, the welding power can flow from the welding power source 28, through a welding cable 80, the welding torch 14, a workpiece 82, and return to the welding power source 28 by by means of a working cable 84 (eg, negative electrode, or direct polarity). Conversely, the welding power can flow from the welding power source 28, through the work cable 84, the workpiece 82, the welding torch 14, and return to the weld power source 28 by means of the welding cable 80 (eg, positive electrode, or reverse polarity).

As can be seen, the training switch 78 can be located

INSTITUTO MEXJCaNO DE LA FkOFIEÜAD INDUSTRIAL physically in any suitable portion of the welding training system 10, such as data reporting device 26, computer 18, and so on.

Furthermore, in certain embodiments, the functionality of the training switch 78 can be replaced by any suitable hardware and / or software in the welding training system 10.

FIG. 2A is a schematic diagram of one embodiment of the welding torch circuitry 14 of FIG. 1. In the illustrated embodiment, trigger switch 72 selectively connects a power supply conductor (eg, the power source). voltage, etc.) to conductor 71. Accordingly, while trigger switch 72 is open, no voltage is applied to conductor 71, and while trigger switch 72 is closed, the voltage from the power supply conductor is supplied to conductor 71. A signal may be provided to enable trigger (eg TRIGGER_EN) via control circuitry 52 to a switch to enable feeder 85. For example, when the trigger enable signal controls training switch 78 to an open position, no voltage is applied to the switch to enable feeder 85 (for example, via the FEEDER_EN connection) thus keeping the switch to enable the feeder 85 in the open position. Conversely, when the trigger enable signal controls training switch 78 to a closed position, voltage is applied to the switch to enable feeder 85, thereby controlling the switch to enable feeder 85 to the closed position. With the switch to enable feeder 85 in the closed position, the conductivity between conductors 74 and 76 is established. Although an example of the welding torch circuitry 14 is provided, any suitable circuitry can be used within the welding torch 14.

In certain embodiments, the position and orientation of workpiece 84 can be provided to the welding training software of the welding training system 10, to calibrate the welding training system 10. For example, a welding operator may provide an indication to the welding training software that identifies which slot 91 of the welding surface 88 the workpiece 84 aligns with. In addition, a predefined welding training task can guide the operator weld to align workpiece 84 with a particular groove 91. In certain embodiments, workpiece 84 may include

For example, as described in greater detail below, A calibration device that is configured to be detected by detection device 16 can be inserted into the first opening 93, or touched to the first opening 93. As the calibration device is inserted into, or touched by, the first opening 93, a user input that is provided to the welding training software (or other calibration software) may indicate that the calibration device is inserted inside the first opening 93. As a result, the welding training software can establish a correlation between a first set of data (eg, calibration data) received from detection device 16 (eg, position and / or orientation data) in a first occasion and location of the first opening 93. The

While the calibration device is inserted into, or touched with the second opening 94, an input User feedback provided to the welding training software may indicate that the calibration device was inserted into the second opening 94. As a result, the welding training software can establish a correlation between a second data set (for example, the calibration data) received from the detection device 16 on a second occasion, and the location of the second opening 94. Therefore, the welding training software may be able to calibrate the position and / or orientation of the welding surface 88 relative to the detection device 16, using the first data set received the first time and the second set of data received the second time.

In certain embodiments, both sides 165 and 166 include blades for cutting the opposite sides of the welding wire, while in other embodiments, only one side 165 and 166 includes a blade for cutting one side of the welding wire and the other side. It includes a surface towards which the sheet is directed. To calibrate the length of the weld wire, the weld wire can extend through opening 162 and into blade unit 164. The welding wire can be cut to a selectable length by pressing the first handle 152 and the second handle 154 against each other, thereby calibrating the length of the wire extending from the torch nozzle. The calibration length can be selected using an adjusting mechanism 167 to adjust a distance 168 between the blade unit 164 and the opening 162 of the torch nozzle holder 156. Therefore, using tool 150, the length of the wire extending from the torch nozzle

can be calibrated.

Figure 8 is a top view of the calibration tool of the exposed portion of the welding wire 150 of Figure 7. As illustrated, the welding torch 14 can be used with the tool 150. Specifically, a nozzle 170 of the Welding torch 14 can be inserted into the torch nozzle holder 156 in one direction 172. Welding wire 174 extending from welding torch 14 is routed through the nozzle inlet

160, opening 162, and knife unit 164. Accordingly, the first and second handles 152 and 154 can be pressed together to cut the weld wire 174 at the distance 168 (eg, the calibration length) to be established by the adjustment mechanism 167.

Figure 9 is an embodiment of a method 176 for calibrating the exposed portion of the wire from the welding torch 14. Tool 150 can be used to calibrate the length of the welding wire 174 extending from the nozzle 170 using a variety of methods. . In method 176, the adjustment mechanism 167 of the exposed portion calibration tool of the weld wire 150 can be adjusted for a length of the selected weld wire 174 (block 178). For example, the distance 168 of the torch nozzle holder 156 from the tool 150 can be configured for a range of between about 0.5 to 2.0 cm, 1.0 to 3.0 cm, and so on. The welding torch 14 can be inserted into the torch nozzle holder 156 of the tool 150, such that the nozzle 170 of the welding torch 14 comes into contact with the torch nozzle holder 156, and that the welding wire Weld 174 extends through opening 162 of torch nozzle holder 156 (block 180). In certain embodiments, the weld wire 174 may be long enough to

Physical 212, 214, 216, and 218 can be laser engraved. Furthermore, in certain modalities ^^ the physical marks 212, 214, 216, and 218 may be visible to the natural eye (for example, within the visible spectrum), while in other modalities the physical marks

212, 214, 216, and 218 may not be visible to the natural eye (eg, not within the visible spectrum).

Each of the physical markings 212, 214, 216, and 218 indicates a location on the welding wire 210 relative to either a first end 220, or a second end 222 of the welding wire 210. For example, the physical marking 212 may indicate a distance from the first end 220, a distance from the second end 222, or some other location relative to the weld wire 210. In certain embodiments, physical marks 212, 214, 216, and 218 may indicate a number that corresponds to first end 220 and / or second end 222. For example, physical mark 212 may indicate a number "1" that indicates which is the first physical mark from the first end 220 and / or the physical mark 212 may indicate a number "4" indicating that it is the fourth physical mark from the second end 222.

the physical marks detected. Accordingly, the data corresponding to the use of the solder wire 210 can be tracked by the solder training system 10 for training and / or analysis.

Figure 12 is a perspective view of one embodiment of a vertical arm assembly 223 of training platform 12 of Figure 4. As illustrated, detection device 16 is attached to first arm 100. In addition, device Detection 16 includes cameras 224, and an infrared emitter 226. However, in other embodiments, detection device 16 can include any suitable number of cameras, emitters, and / or other sensor devices. A pivot assembly 228 engages the first arm 100 and the detection device 16, and allows an angle of the detection device 16 to be adjusted while the detection device 16 rotates as illustrated by arrow 229. As can be appreciated, adjusting the angle of the detection device 16 relative to the first arm 100 changes the field of view of the detection device 16 (for example, to change the portion of the weld surface 88 and / or the weld surface 112 which is detected by detection device 16).

A wire 230 runs between knob 101 and sensing device 16. Wire 230 is guided by pulley 232 to facilitate rotation of sensing device 16. Therefore, a welding operator can rotate knob 101 for manually adjusting the angle of detection device 16. As can be seen, the combination of cable 230 and pulley 232 is an example of a system for rotating detection device 16. It should be noted that any suitable system can be used to facilitate the rotation of the detection device 16. Although an embodiment of a knob 101 is illustrated, it can be appreciated that any suitable knob can be used to adjust the angle of the detection device 16. In addition, the angle of

detection device 16 can be adjusted using a motor 234 that is coupled to cable 230. Accordingly, a welding operator can operate motor 234 to adjust the angle of detection device 16. Furthermore, in certain embodiments, the control circuitry can be coupled to motor 234 and can control the angle of detection device 16 based on a desired field of view of detection device 16, and / or based on tracking a object within the field of view of the detection device 16.

The raised welding arm assembly 235 illustrates an embodiment of a manufacturing design that allows the second arm 106 to be height adjustable. Accordingly, as can be appreciated, the second arm 106 can be manufactured to have an adjustable height in various ways. As illustrated, the raised weld assembly 235 includes handles 236 used to vertically raise and / or lower the second arm 106 as illustrated by arrows 238. The raised weld arm assembly 235 includes a locking device 240 for immobilize the second arm 106 at a desired height. For example, locking device 240 may include a button that is depressed to release a detent that is configured to extend into openings 242, thereby releasing the latch on second arm 106 by releasing it from side rails 243. With second arm 106 Released from side rails 243, handles 236 can be vertically adjusted to a desired height, thereby adjusting plate 112 to a desired height. As can be appreciated, releasing the button can result in the detent extending into openings 242 and attaching second arm 106 to side rails 243. As can be appreciated, locking device 240 can be operated manually as described, and / or the locking device 240 can be controlled by a control system (for example, controlled

For example, in certain embodiments, the welding training software can control the second arm 106 to move to a desired position automatically. Therefore, plate 112 can be adjusted to a desired height for elevated welding.

TRAINING SOFTWARE FOR WELDING IN MULTIPLE MODES

FIG. 14 is a block diagram of one embodiment of the weld training software 244 of the weld training system 10 having multiple training modes. As illustrated, the welding training software 244 may include one or more of a live arc mode 246 that is configured to allow training using a live (eg, actual) welding arc, a simulation mode 248 which is configured to enable training using a welding simulation, a virtual reality (VR) mode 250 which is configured to allow training using a VR simulation, and / or an augmented reality mode 252, which is configured to allow training using augmented reality simulation.

The welding training software 244 can receive signals from an audio input 254. The audio input 254 can be configured to allow a welding operator to operate the welding training software 244 using audible commands (for example, the voice activation). Also, the 244 solder training software can be configured to provide 256 audio output and / or 258 video output. For example, welding training software 244 may provide audible information to a welding operator using audio output 256. Audible information may

include instructions for configuring (eg installing) the welding training system 10, the real-time feedback provided to a welding operator during a welding operation, instructions for a welding operator before performing an operation Welding, the instructions for a welding operator after performing a welding operation, warnings, and so on.

Figure 15 is a block diagram of a VR 250 mode mode of the 244 welding training software. The VR 250 mode is configured to provide a welding operator with a simulation of VR 260. The simulation of VR 260 can Show yourself to a welding operator through a VR viewfinder, VR glasses, a VR display, or any suitable VR device. The VR 260 simulation can be configured to include a variety of virtual objects, such as the objects illustrated in Figure 15, that allow interaction between a weld operator and a virtual object selected from the variety of virtual objects within the VR 260 simulation. For example, virtual objects can include a virtual workpiece 262, a virtual welding rig 264, a virtual welding torch 266, virtual wire cutters 268, a virtual software setup 270, the virtual data results from training 272, and / or a virtual glove 274.

In certain modes, the weld operator can interact with virtual objects without touching a physical object. For example, detection device 16 can detect movement of the weld operator and can lead to similar movements that occur in the VR 260 simulation, depending on the movements of the welder operator in the real world. In other embodiments, the welding operator may use a glove or welding torch 14 to interact with the

IMPT

INSTITUTO Mc.'íJCANO Γ »Ε LA PMC.'IELMU 'NrUSTHlAL virtual objects. For example, the glove or welding torch 14 can be detected by detection device 16, and / or the glove or welding torch 14 can correspond to a virtual object in the VR 260 simulation. In addition, the welding operator may be able to operate the welding training software 244 within the VR 260 simulation using the virtual configuration of the software 270 and / or the results of the virtual data from the training 272. For example, the welding operator can use his hand, glove, or welding torch 14 to select the items within the welding training software 244 that are displayed virtually within the VR 260 simulation. On the other hand, the The welding operator can perform other actions such as picking up the wire cutters and cutting the virtual welding wire extending from the virtual torch 266, all within the VR 260 simulation.

Figure 16 is a modality of a 276 method for integrating data from training results. Method 276 includes the soldering training software 244 of computer 18 that receives a first set of soldering training data from a storage device (eg, storage device 24) (block 278). The first set of welding training data can include the welding training data that corresponds to a first welding training task. Method 276 also includes welding training software 244 that receives a second set of welding training data from the storage device (block 280). In certain embodiments, the first set and / or the second set of weld training data can be received from a network storage device. The network storage device can be configured to receive welding training data from it, and / or to provide training data for

weld on, weld training system 10 and / or external weld training system 40. Weld training software 244 can integrate the first and second weld training data sets into one graph to allow visual comparison of the first weld training data set, with the second weld training data set (block 282). As can be appreciated, the graph can be a bar graph, a circle graph, a line graph, a histogram, and so on. In certain embodiments, integrating the first weld training data set with the second weld training data set includes filtering the first weld training data set and the second weld training data set to show a subset of the first weld training data set and a subset of the second weld training data set. The welding training software 244 can provide the graph to a display device (eg, screen 32) (block 284). In certain embodiments, providing the graph to the display device includes providing the selected elements on the graph which, when selected, display the data corresponding to a respective selected element of the selectable elements (for example, selecting the wire speed from the graph may change display to show wire speed history for a particular weld training task).

The first set of welding training data and / or the second set of welding training data may include a welding torch orientation, a welding torch travel speed, a welding torch position, a distance from the contact tip to the workpiece, a proximity of the welding torch relative to the workpiece, a sight of the welding torch, a weld score, a degree of welding, and so

Furthermore, the first set of welding training data and the second set of welding training data may correspond to the training performed by a welding operator and / or by a class of welding operators. In addition, the first welding training task and the second welding training task may correspond to the training performed by a welding operator and / or by a class of welding operators. In certain embodiments, the first welding training task may correspond to the training performed by a first welding operator, and the second welding training task may correspond to the welding performed by a second welding operator. Furthermore, the first training task and the second training task may correspond to the same welding training scenario.

Figure 17 is an embodiment of a graph 285 illustrating multiple sets of welding training data for a welding operator. Graph 285 may be produced by welding training software 244 and may be provided to screen 32 for use by a welding instructor to review welding training operations performed by a welding student, and / or may be provided to Screen 32 to be used by a welding student to review the welding training operations performed by that welding student. Graph 285 illustrates a comparison of the bar graph between different training tasks for a first set of welding training tasks performed by a welding operator. The first set of welding training tasks includes tasks 286, 288, 290, 292, and 294. Graph 285 also illustrates a comparison of the bar graph between different training tasks for a second set of training tasks for Weld

'Ndustrul that is performed by the welding operator. The second set of welding training tasks includes tasks 296, 298, 300, 302, and 304. Accordingly, welding training tasks can be compared to each other for analysis, instruction, certification, and / or training purposes. As illustrated, welding training tasks can be compared against each other using any of a number of criteria, such as a total score (PT), a working angle (AT), an angle of displacement (AD), a speed of displacement (DV), a contact distance to work (DCT), a proximity (P), a mode (for example, arc with current mode (MAC), simulation mode (MS), etc.), completion status (for example, complete, incomplete, partially complete, etc.), a type of joint (TU) (for example fillet, butt, T, overlap, etc.), a welding position (PS) (for example, flat, vertical, raised, etc. ), a used metal type (MU), a filler metal type (MA), and so on.

FIG. 18 is an embodiment of a graph 305 illustrating the welding training data for a welder compared to the welding training data for a class. For example, Graph 305 illustrates a score 306 from a welding operator compared to a score 308 (eg, average, median, or some other score) from a class for a first task. In addition, a welder operator score of 310 is compared to a class score of 312 (eg, average, median, or some other score) for a second task. On the other hand, a weld operator score of 314 is compared to a class score of 316 (for example, average, median, or some other score) for a third task. As can be seen, the scores of one or more welding operators can be compared to the scores of the entire class. Such a comparison allows an instructor to

Furthermore, in some embodiments, the first welding process, the second welding process, the first welding device, and / or the second welding device of a welding system may be enabled or disabled depending on at least part of the response. . On the other hand, in certain embodiments, the first welding process, the second welding process, the first welding device, and / or the second welding device of a welding system can be turned on or off automatically. Therefore, the certification data of a welding operator can be used to activate and / or deactivate that ability of the welding operator to use a particular welding system, welding device, and / or welding process. For example, a welding operator may be certified for a first welding process, but not for a second welding process. Consequently, in certain modalities, a welding operator can verify his identity in a welding system (for example,

IMPI

registering or some other form of authentication). After the identity of the welding operator is verified, the welding system can review the status of the welding operator's certification. The welding system may allow the welding operator to perform operations using the first welding process, depending on the status of the welding operator's certification, but may block the second welding process from being performed to the welding operator, depending the status of welding operator certification.

Figure 20 is an embodiment of a display 327 illustrating the data corresponding to a training weld. Screen 327 can be produced by welding training software 244 and can be displayed on screen 32. Screen 327 illustrates parameters that can be graphically displayed to a welding operator before, during, and / or after performing a welding operation. For example, parameters may include a working angle 328, a displacement angle 330, a distance from the contact tip to the work piece 332, a travel speed of the welding torch 334, a proximity of the welding torch in relative to workpiece 336, a welding voltage 337, a welding current 338, an orientation of the welding torch, a position of the welding torch, a sight of the welding torch, and so on.

Furthermore, the welding training software 244 can be configured to extract the video data from the storage device 24, to extract the welding parameter data from the storage device 24, to synchronize the video data with the welding parameter data, and to provide the synchronized video data and welding parameter data to screen 32.

Weld training software 244 can analyze the weld parameter data to determine a traveled path 344 that can be displayed on screen 32. In some embodiments, a time 346 can be selected during a weld by a weld operator. . By selecting time 346, the welding operator can view the video playback 342 and / or the path traveled 344 together with the welding parameters as they were at the selected time 346 in order to establish a correlation between the welding parameters, video playback 342, and / or path traveled 344.

failure medium, the weld is partially defective). Moreover, between the times

360 and 362, there is a high discontinuity, and between times 364 and 366, there is a low discontinuity (eg, the quality of the weld is good, the weld has a low probability of failure, the weld is not defective). With this information, a welding operator may be able to quickly analyze the quality of a welding operation.

FIG. 22 is a block diagram of one embodiment of a welding instructor display 368 of the welding training software 244. The welding training software 244 is configured to provide training simulations for many different welding configurations. For example, welding setups may include a MIG 370 welding process, a TIG 372 welding process, a conventional 374 electrode welding process, 346 current arc welding mode, simulation welding mode

248, virtual reality welding mode 250, and / or augmented reality welding mode 252.

Welding instructor display 368 can be configured to allow a welding instructor to restrict the training of a 376 welding operator (for example, to one or more selected welding configurations), restrict the training of a class of 378 welding operators (for example, to one or more selected welding configurations), and / or restrict the training of a portion of a class of 380 welding operators (for example, to one or more selected weld settings). Furthermore, the welding instructor display 368 can be configured to allow the welding instructor to assign the selected training tasks to the welding operator 382, to assign the selected training tasks to a class of welding operators 384, and / or

In addition, the <dé ^ solcla <Jara 300 puuck »instructor screen is configured to allow the weld instructor to automatically advance the weld operator (or a class of weld operators) from a first training task to a second training task 388. For example, the welding operator may advance from a first training task to a second training task depending at least in part on a quality of completion of the first training task.

Figure 23 is an embodiment of a 389 method for welding training that uses augmented reality. A welding operator can select a training mode from the welding training software 244 (block 390). The welding training software 244 determines whether the augmented reality mode 252 (block 392) has been selected. If augmented reality mode 252 has been selected, the welding training software 244 runs an augmented reality simulation. It should be noted that the welding operator may wear a welding helmet and / or some other head accessory that is configured to place a display device in front of the welding operator's view. Furthermore, the display device can be generally transparent to allow the welding operator to see real objects; however, a virtual welding environment can be represented on portions of the display device. As part of this augmented reality simulation, the welding training software 244 receives a position and / or an orientation of the welding torch 14, such as from detection device 16 (block 394). The 244 welding training software integrates the virtual welding environment with the position and / or orientation of the welding torch 14 (block 396). Moreover, 244 welding training software provides the environment

mexican institute of THE AMMONITY INtXJSTJjTO THE > (block 398). Per axis

virtual welding machine, the welding training software display device 244 can determine where should you weld weld be within the field of view of the welding operator, and the welding training software 244 can show the weld bead in the display device such that the weld bead appears to be on a workpiece. After completing the weld, augmented reality simulation can allow the weld operator to remove a portion of the virtual weld environment (for example, weld bead) (block 400), and weld training software 244 returns to block 390.

If the augmented reality mode 252 has not been selected, the welding training software 244 determines whether the arc mode with current 246 has been selected (block 402). If current arc mode 246 has been selected, welding training software 244 enters current arc mode 246, and the welding operator can perform current arc welding (block 404). If current arc mode 246 has not been selected and / or after executing block 404, the welding training software 244 returns to block 390. Accordingly, the welding training software 244 is configured to allow a welding operator to practice a weld in augmented reality mode 252, to remove at least a portion of the virtual welding environment from the practice weld, and to perform a live weld in 246 live arc mode. In certain embodiments, the welding operator can practice welding in augmented reality mode 252 consecutively a multiple number of times.

Figure 24 is an embodiment of another method 406 for welding training using augmented reality. A welding operator can select a training mode from the welding training software 244 (block 408). The

INSTITUTO MEXíCA-áC t <- »·r·· ^, DE '.A i'SCtILLVu <weld training software 244 determines if augmented reality mode 252 (block 410) has been selected. If the augmented reality 'nrrodo 252 has been selected, the welding training software 244 runs an augmented reality simulation. It should be noted that the welding operator may wear a welding helmet and / or some other head accessory that is configured to place a display device in front of the welding operator's view. Furthermore, the display device can completely block the field of view of the welding operator in such a way that the images observed by the welding operator have been captured by a camera, and displayed on the display device. As part of this augmented reality simulation, the welding training software 244 receives an image of the welding torch 14, such as from detection device 16 (block 412). The 244 welding training software integrates the virtual welding environment with the image of the welding torch 14 (block 414). Furthermore, the welding training software 244 provides the virtual welding environment integrated with the image of the welding torch 14 to the display device (block 416). For example, welding training software 244 can determine where a weld bead should be placed within the field of view of the welding operator, and weld training software 244 displays the weld bead on the display device with the image of the welding torch 14 and other objects in the welding environment. After completing the weld, augmented reality simulation can allow the weld operator to remove a portion of the virtual weld environment (for example, weld bead) (block 418), and weld training software 244 returns to block 408.

If 252 augmented reality mode is not selected, the software

Training 244 determines whether arc current mode 246 has been selected (block 420). If 246 live arc mode has been selected, the welding training software 244 enters current 246 arc mode and the welding operator can perform current arc welding (block 422). If current arc mode 246 has not been selected and / or after executing block 422, the welding training software 244 returns to block 408. Accordingly, the welding training software 244 is configured to allow a welding operator to practice a weld in augmented reality mode 252, to remove at least a portion of the virtual welding environment from the practice weld, and to perform a live weld in 246 live arc mode. In certain embodiments, the welding operator can practice welding in augmented reality mode 252 consecutively a multiple number of times.

As can be appreciated, using the systems, devices, and techniques described herein, a welding training system 10 can be provided to train welding operators. The welding training system 10 can be cost-effective and can allow welding students to receive high-quality hands-on training.

Although only certain features of the invention have been illustrated and described herein, many modifications and changes will occur to those skilled in the art. It will be understood, therefore, that the appended claims are intended to cover all those modifications and changes that fall within the true spirit of the invention.
