Welding methods for 304, 304L, and 316L stainless steels?? The contractor needs to purchase welding rods for record-keeping. Could those of you who have experience with these materials tell me the welding methods for each type of stainless steel??? Good answers will earn 10 points
Is there a difference?? It’s not the case that argon welding can be used in all situations; one just needs to pay attention to the fact that 304 and 304L require the same type of welding rod, while 316L requires a 316L welding rod
304 has excellent ductility, and can be welded using MIG welding or TIG welding without the need for any special treatment. 316L and 316 stainless steels also possess good weldability. All standard welding methods can be used for welding. It uses non-melting (tungsten) electrode (pulsed) TIG (or mixed gas) shielded welding, with a one-sided welding two-sided formation process, resulting in lower equipment costs.
304 is the most common type of stainless steel, and the most common welding materials are used as well. For pipes, H0Cr18Ni9Ti+A132 is used; for 304L, ER308L+A002 is employed; and for 316L, EL316L+A022 is used. Welding with these materials works fine, and we have welding procedure specifications that have been approved
The welding rod must be heated to over 80°C and kept at that temperature.
