In the metal stamping industry, we occassionaly have the "OOPS!" in the pressroom that cracks a piece of tool steel and our local welder guy is lately booked up. We have in house heat-treat, a little GTAW runner, and my hands/eyes are capable to "zap" some of these back together, for a temporary patch until a new toolsteel piece can be machined,HT'd,EDM'd,fit and ready togo. Sometimes the turn around can shut our customers down for days,weeks,ect. and that just can't happen. I'm having trouble finding the "right" filler for these little projects; both what IS the right rod, and where do i get it? my local consumable supplier is unsure, but if can give the rep the type of filler, I feel confident he can get it in small quantities I need(1-2#'s of 1/16,5/32 would last a couple years). The types of steel for repair would be 4140, A2, D2, & CPM M2,M4 if possible on the pm stuff. Any advice on pre-heat temp's/post weld temper would also be extremely greatfull.
thanks, Cory.
