[MW:8177] Renewal of Welder Qualification

Greetings,

 

 Code: ASME IX

Process: GTAW

Diameter: DN50

Specs: ASTM A106

Qualification Status: expired

 

As per QW 322.2

    Providing the conditions of QW-304 and QW 305 are satisfied, renewal of welder qualification under QW-322.1(a) may be done on production work.

 

QW 304

     Alternatively, welders making a groove weld using SMAW, SAW, GTAW, PAW, and GMAW (except for short circuit mode) or combination of these process maybe qualified by radiograph examination,

 

 Does this sentence applied if the welder has welded the following 3 months prior to his expiration of his ASME qualification, welding as per below:

Code: DNV-OS-F101

Process: GTAW

Diameter: DN50

Grade: DNV 450

 

 

Can the welder  renew his qualification on production work as per QW 322.2, under this circumstances?

 

Does this production work means that it is the work that needs qualified welders to do the work?

 

 

 

 

Thank you in advance.

 

 

 

 

Cheers,

 

Larry
