I would like to know reg Sec IX,QW 200.2(f) and QW 200.4(a)
200.2(f) states " A single WPS may cover several essential variable
changes......(eg. a single WPS may cover a thinkness range from 1.5mm
thru 32mm if PQR exist for both 1.5 to 5mm and 5mm thru 32 mm ranges)
But QW 200.4(a) states if all essential/supplementary essential
variable according to QW 451 is meeting then ......
My doubt is this: As per 200.2(f), "Base metal range" is not meeting
the requirement of QW 451.
But QW 200.4(a), states base metal thickness range, weld metal
thickness range etc shall meet QW 451.
Can anybody please clarify...
