Tracking Motions Of Manually Controlled Welding Torches

Techniques for measuring motions of manually controlled welding torches undergoing development. Positions, orientations, and velocities determined in real time during manual arc welding. Makes possible to treat manual welding processes more systematically so manual welds made more predictable, especially in cases in which mechanical strengths and other properties of welded parts highly sensitive to heat inputs and thus to velocities and orientations of welding torches.

Process-Information Display Panel For Welder's Visor

Head-up display (HUD) unit mounted in welder's visor or helmet provides process information in real time. Display enables welder to gain greater awareness of effects of welding while controlling welding process in usual way(s) by use of foot pedal, voice command, and/or manipulation of welding torch. Possible to avoid need for every new welder on job to solve same problems solved by other welders. Graphical display presented to welder, adjacent to normal field of view through visor. Beneficial in supporting and enhancing continued practice of manual arc welding. Valuable in industries that invest millions of technician-hours each year in manual arc welding for variety of products.
