Up Topic Welding Industry / General Welding Discussion / Welder Qualification for 3G per D1.1
- - By newguy Date 02-17-2005 13:47
Need clarification on what a welder qualifies for when taking a test on plate in the 3G position. To my understanding D1.1 qualifies a welder to weld PIPE:
over 24 in., CJP & PJP (butt-groove), 1G Rotated & 2G
over 24 in., PJP (T,Y,K-groove) consider note 5, 1G Rotated & 2G
Any size, FILLET, 1F & 2F Rotated & 2F

Please comment, I need to know if this is correct or not.

Looking at Table 4.9, I see:

(1) over 24 in., CJP & PJP (butt-groove), 1G Rotated & 2G... to this add vertical

(2) over 24 in., PJP (T,Y,K-groove) consider note 5, 1G Rotated & 2G... to this add vertical

(3) Any size, FILLET, 1F & 2F Rotated & 2F... to this add vertical

Also see Table 4.10 and notes. If the test coupon was 1", then the thickness is 1/8" to unlimited. If less than 1", then limited to 1/8" to 2T.
