I am taking a pipe weld test on nickel 200 (99.9%) nickel. the test is on 2 inch schedule 10 in the 6g position. we are allowed 3/32 reinforcement on both root and face. 3/32 root opening max and 5 p s I on inner purge only. I am keyholing the root and seem to do ok but sometimes get too much reinforcement. does anyone have any advice
Reply:sorry guys I made a mistake on my post. I meant to say 1/16 reinforcement on the root and cap. not 3/32
Reply:Are you using.....have you tried 1/16 filler wire?
Reply:no 3/32 is all that's allowed. and no fusion either. this is a tough test.
