Hi
 
Yes you are right but it is only applicable for Thickness of Weld Metal Qualified with minimum of three layers.

Subject: [MW:10246] ASME IX - Welder's qualification Thickness range

Hi all,

  As per ASME sect IX table QW-452-1(b), for welder's qualified in test coupon thickness greater or equal than 13 mm, he's will be qualified to wed thickness " Maximum to be welded"

May my interpretation is true ??
In this case, Can i  qualify all welder's in 13 mm thickness, he will be qualified for all thick ( PWHT is not essential variable for welders) and cover all thickness range ?

Regards
