Dear Mr. Saleem

Please note that as far the essential variables of the welder are within the ranges of the second WPS, the welder is qualified to weld using the second or any number of WPS.

Please note for welder qualification actual essential variable and the qualified essential variables alone are mandatory in the Report and the WPS used for welding coupon is non mandatory as per my knowledge.
