Weld or tack-weld overlapping edges of positioned components.
What does a Gun Welder do?
Welds or tack-welds overlapping edges of positioned components to fabricate sheet metal assemblies, such as panels, refrigerator shells, and automobile bodies, using portable spot-welding gun: Positions and clamps electrode under overlapping edges of workpiece. Presses electrode against workpiece at specified weld points to complete circuit between electrodes and heat metal to joining temperature. Removes electrode after specified period of time. May adjust equipment for automatic timing of current. May periodically attend group meetings to learn new or modified tasks. May position and clamp workpieces together. May examine welded components to detect defects.
