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.
