Question

Quizplus · Accepted Answer

The least likely true statement is D because in MIG stitch welding, the standard nozzle is typically used, not a specialized spot nozzle. The spot nozzle is more commonly associated with spot welding processes, not stitch welding. Stitch welding involves creating a series of welds along a seam or joint, which doesn't necessitate a specialized spot nozzle.
