Re: [MW:22471] number of welding process in D1.1

Dear friend,

1 - Yes. You can, but it need WPS requalification. (see Table 4.7. item 18 - 2010 Ed.)

2 - The "ability to weld" and the "qualification" are two different things. It is probable that the welder could weld many types of joints in different positions and so on, but he has just 1 qualification. It means that he permits to weld just in the criteria of his qualification (and it doesn't mean that he is not able). So if your welder has ASME certificate and want to weld a part based on D1.1, he (or may be you) should prepare a new qualification based on D1.1.

Hi All

1- Can we have more than one process in WPS based on D1.1 or not? please give me reference 

2 - Can we use one of the welding process from Section 9`s WPS for welder qualification, if welder should be qualified based on D1.1 ? (attention : test coupon will be test based on D1.1 criteria ) give me Guide line please.

Thanks everybody
