Abstract: Systems are disclosed relating to a mobile device mounted to a welding helmet such that a wearer of the welding helmet can see a display of the mobile device when wearing the welding helmet. In some examples, the mobile device is mounted such that a camera of the mobile device is unobscured and positioned at approximately eye level, facing the same way the wearer's eyes are facing. In some examples, the simulated training environment may be presented to the user via the display screen of the mobile device, using images captured by the camera of the mobile device, when the mobile device is so mounted to the welding helmet.

Abstract: Described herein are examples of tool based welding technique monitoring systems that provide an inexpensive, intuitive, and relatively robust way of tracking an orientation of a welding-type tool, and providing welding technique feedback based on the orientation. The system requires no sensors apart from a simple and/or relatively inexpensive sensor module that can be mounted to travel with the welding-type tool, which makes the system highly portable. Additionally, calibration of the system can be accomplished with fast, simple, intuitive calibration techniques.

Abstract: Systems for simulating joining operations, such as welding, are disclosed. In some examples, a system may use a mobile device for conducting welding simulations, such as for purposes of training. In some examples, the system may additionally, or alternatively, use modular workpieces. In some examples, the system may additionally, or alternatively, conduct the welding simulation based on one or more selected pieces of welding equipment.

Abstract: Described herein are examples of weld training systems that show (e.g., transparent and/or translucent) “ghost” images of a welding tool on a display screen of a welding headgear to indicate target positions and/or target orientations of an actual welding tool. In some examples, the weld training systems may additionally “reset” the target tool image to a position closer to the actual welding tool if the target tool image gets too far away. The ability to “reset” the target tool image to a position closer to the actual welding tool may help in minimizing a risk that an operator 106 will overcompensate to try to catch up with the target tool image, which can be detrimental to the weld. Additionally, resetting the target tool image to a position closer the welding tool may allow an operator to better perceive and/or understand differences in orientation and/or other technique parameters.

Abstract: An example welding system includes: a downdraft table having: a work surface; and a suction source configured to create a negative pressure through at least one of the work surface or a second surface adjacent to the work surface; and a positive pressure source configured to direct a positive pressure airflow around at least a portion of a periphery of the downdraft table.

Abstract: Described herein are examples of welding simulation systems with observation devices that facilitate the types of group interactions that occur in conventional weld training. In some examples, third party observers may use the observation devices to observe the welding simulation from their own perspectives. In some examples, this may allow for traditional “over the shoulder” observation, and/or group/classroom observation and interaction.

Abstract: An extraction system is designed for metal working and other applications. The system employs a pneumatic filter cleaning device with a pneumatically driven extension guide arranged within a chamber. The guide is coupled to a first end of an extension member, which has a nozzle secured to a second end. Pressurized air provided to the nozzle through the extension member increases until a pressure at the nozzle reaches a threshold pressure level. Once the threshold pressure level is achieved, the nozzle releases a pulse or burst of air directed to a filter medium. The force from the pulsed air dislodges airborne components from the filter media, resulting in a cleaned filter.

Abstract: The disclosed filter and/or debris disposal system is configured to easily dispose of filter elements, filter media, and/or debris with minimal resources, and/or effort. In some examples, a flexible container is employed to enclose a used filter element prior to removal of the filter from the extractor.
