What the process covers
Spot welding joins overlapping sheets by passing current through electrodes that clamp the joint. Projection welding uses raised points on a nut, stud or part to place the weld. Both run in fixtures that hold every part in position, so each weld lands in the same place on every assembly.
ENCO’s welding capacity
31 projection welders for nuts and bolts, 11 Fanuc and Kuka spot-welding robots, and 8 integrated-transformer spot guns, hand-held and robotic.
