My bad,there's so many P #'s flying around at work I personally think it's way easier to keep it straight by calling it by the name,Inco,Carpenter 20,Monel,Hastelloy,chromes,stainless, But the SMAW procedure for 2" monel pipe flat out SUCKS.I switched from contract working at one refinery to being employed by another,one outfit called everything by namethis new outfits all about the P's.Been a year and I still get them all cornfused.The one joint would never think about sticking a alloy joint from root to cap and this new one is fine with it.Whatever peels their taters I guess,all I know is it's messy business.The lead welder said in the old days when they were welding the crap with stick they had a 75% repair rate he said you'd just keep grinding it out and fixing till it shot good,ICK!
