Welding 4130
Welding 4130
(OP)
I need to weld a seam in 1/4" thick 4130 which will be heat treated. It will be seeing very high impacts infrequently. Can you suggest a welding filler material to be used by a mig or arc welder? Suggestions on heat treatment schedule would also be helpful although I think I have this area covered.
Thank you,
Seth

For UTS of 125ksi or less, use E70-S2 filler.
For UTS > 125ksi use 17-22AS filler.

If the above information is not applicable to your situation, or you need more specifics, you need to post more specific information about the base metal and what properties the weld needs to have. The keys are knowing what you have to weld on and knowing what you need when you are done. (property wise)
