We are trying to improve feedability of welding wire for robotic applications, what are the ways to improve good feedability?
copper coating, adding low ionization potential elements in coating etc.... what can be done?
we would like to weld 415 martensitic stainless steel(UNS S41500). can anyone suggest what filler material cand be used to get almost equal to the base metal strength and there is no scope of PWHT.
