WPS/WPQ Thickness Range Qualified Question
WPS/WPQ Thickness Range Qualified Question
(OP)
Hello all,
I am certifying a new procedure using GTAW root and GMAW filler metal. Welder is qualifying on a 2" sch-160 coupon in 6G position with 1/8" Gap. Actual deposit values for GTAW root is .144" and .373" for GMAW filler.
Am I correct that:
WPS Groove thickness range would be GTAW .0625"-.288" and GMAW .0625"-.746" (2t for each)?
WPQ Deposit Thickness range qualified would be the same?
Thanks in advance,

The base metal thickness range on the WPS would be 2* coupon thickness.
The weld deposit thickness ranges would correspond to adjusted values above for the respective welding processes using 2t.
