Re: [MW:28054] WPS Qualification as per QW-451.

Dear,

Variables mentioned in table are applicable to specific process only.

Same shall not be applied to other process.

In your case same is not applicable. Need to qualify WPS.

Background : PQR qualified on coupon : 10.97 mm
WPS Qualified : 10.97- 21.94 mm(impact)

As per QW-451, WPS qualified up to 21.94 mm. Can we used that WPS for 24.00 mm Thickness. grove weld by considering Qw-403.3, : increase in 20 % in base metal thickness when the test coupon thickness is less than or equal to 25 mm.
