[MW:12381] Re: WPS based on contractor PQR

Dear Mr.Pradip Goswami
I agree with your reply.But as per ASME B31.3,the word " Procedure qualification by others" confusing.The others may be some manufacturer or contractor not related to project or work.In our case we are the EPC contractor,we are taking responsibility.

Mr. Padmanabhan,

 

Sec-IX, QW-201 addresses  Manufacturer's or Contractor's Responsibility on performing welding. However the requirements of each design code could be different.

 

As the design code is B-31.3 you need to see the requirements of B-31.3(I' referring to 2008 edition). Clause   328.2.2 Procedure Qualification by Others specifies clearly what needs to be followed for adopting a weld procedure qualified by another organization. Clauses 328.2.2 (a) to (i) all are applicable

 

Clause 328.2.3 Performance Qualification by Others.- specifies what require to be done for transfer of qualification for welders to the present employer

 

I hope  clause 328.2.2 and 328.2.3 would help to clarify your query.

 

Thanks.

Hi,
As per ASME Sec IX,  EPC Contractor qualified WPS/PQR for carbon steel material.Based on contractor qualified PQR,whether subcontractor can prepare WPS and use for welding. EPC contractor will take operational control and responsibility of welding activities.

 code of construction is ASME B31.3.

Please throw some light on QW 200.
