Re: [MW:10311] ASME IX - Welder's qualification Thickness range



Dear Sir,
Your interpretation is correct and only condition is it shall be welded by using multi pass weld and not single pass weld. So dont confuse with the thickness and go ahead with 13 mm or greater and weld .




Thanking You,

Honesty is the best Policy

Hi Martin
 
If that is the case , we can't qualify the welder for unlimited thickness as the WPS has not qualified for unlimited thickness ?

>In my opinion , "Maximum to be welded" indicates the unlimited thickness.

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.
