RE: [MW:10270] ASME IX - Welder's qualification Thickness range

Dear Sir,
 
Your interpretation is true within the limits of your applicable qualified WPS. E.G. if your applicable WPS is qualified for max thickness 20 mm and your welder has welded 16 mm thk test coupon then the "Maximum to be welded" thikness is 20 mm.
 
Please note that you can not go beyond the applicable qualified WPS.
 
regards,
Martin.

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
