| Hi, Sorry, the test coupon was 8"dia x 1/2" thick. My mistake. Root, HP - SMAW, Rest- FCAW. Now, with this can the welder use SMAW alone to weld on some other joints within the Code ? Hope I am eligible for an answer this time. Thanks, S Vagal

also note that qualification required on =>1/2" thickness pipe. Hi, AWS D1.1 does not restrict weld metal deposit. It restrict base metal thickness.

Now, if we want to use these welders for full SMAW - i) Is it allowed? ii) What is the new qualification to? S Vagal |
