AS per ASME Section IX the welder Performance qualification -thickness of weldmetal qualified range is given as
1. "All" weld metal thickness ----range of approval is 2 times the thickness welded
2.13mm and above with minimum three layers -range of approval is maximum to be welded
I could not understand the meaning "All " if it means all weld metal thickness means why the 13mm and above range is given
