We are welding castings made of FSX-414 . Cobalt based alloy. We have a lot of shrink in the castings and are salvaging them for production. We have to rout thru-holes in them(about .250 wall thickness) and are back purging. The problem is (problems are) we are getting either cracking where the close-up is,or we are getting gas in the welds. Any ideas?

P.S. We use MAR-M-918 filler. Thanks !
