Hi,
 
AWS D1.1 does not restrict weld metal deposit. It restrict base metal thickness.

Hi all,
We qualified some welders to 6GR on  6" dia x 7 mm thick pipes using SMAW  for root + hp (deposited about 4 mm) followed by FCAW. Now, if we want to use these welders for full SMAW - i) Is it allowed? ii) What is the new qualification to?
