Question about metal work:Is it possible (that is practical)to weld Chrom Moly alloy to basic steel?
Just curious as to what is current state-of-the-art in TIG welding, I believe it shoud be possible to weld almost anything to anything (exception being brass & aluminium alloys) but what about either Stainless Steel or plain steel welded to Chrom Moly? any answers, links ... or?
Certainly its possible and regularly done. One of the acceptable filler rods for 4130 cromo is mild steel. You can join 4130 to mild steel without difficulty provided you treat the 4130 part properly-425F preheat and postheat to make sure it doesnt crack. eutectic makes a rod called tigtectic 66 AKA "copycat"rod which could also be used.
One thing you shouldnt do it stick weld or mig weld 4130
