Welding Module 5 – Review Questions and Answers Already Passed Nibblers prepare base metal edges using a reciprocating punch. One type of joint used with a plug and slot weld is a lap joint. Common-grade stainless steels typically contain at least 11% chromium. Surfacing welds serve to build up surfaces. Metal cutting through oxyfuel, plasma arc, or air-carbon arc processes is known as thermal cutting. Common grade stainless steels are categorized based on their grain structures. It'...
