Welding of dissimilar metals

Welding of dissimilar metals

I need some information on welding 430 (or 430F)
stainless steel to 304 or 316.
Is it possible using TIG, beam or laser welding?
What are the concerns when welding these materials
together if any?
What filler rod is recommneded?
Any other information would be greatly appreciated
Thank You,

Vince Maffei

RE: Welding of dissimilar metals

317 filler is use when welding two differents tipe of stainless steel  the equipment use is  regular TIG  with ARGON,  to clean the parts  wire brushes  and  related tool should be  made of ss also to avoid any contamination.

Try the AWS WHB Series Hdbks... or go to the ASM website and check-out books on SSTLs - Wil Taylor

RE: Welding of dissimilar metals

We weld this combination quite often. The low carbon grades (304L or 316L) create a better weld. We use only 430. We do not use 430F for welds. I know other companies use TIG and Laser, but we use only E.B. We do not use fillers but keep gaps to a minimum of .002". Parts also have to be very clean. We do not weld inhouse but use E.B. Industries. ( We manufacture solenoid valves for primarily aerospace applications from this combination.
