Re: [MW:14833] USE of PQR for more than one Subcontractors

The answer is no.

As per Sec. IX of ASME-

QW 200.1, Each manufacturer and sub contractor shall prepare written welding procedure Specification.

QW 200.2, Each manufacturer or subcontractor shall be required to prepare a Procedure Qualification record.

You can note the difference in both.

QW 201 states that, 'the code recognizes a manufacturer or contractor as the organization which has responsible operational control of the production of the weldments to be made in accordance with the Sec. IX code.

Hence, it is more appropriate if the manufacturer or contractor prepares the WPS & PQR in their name and ask the subcontractors like C, D or E  or others to follow it.

QW 302 do not come into the picture at all.

Subject: [MW:14830] USE of PQR for more than one Subcontractors

Dear Experts.

 

Let us suposse client is A & B is Contractor.

Under B ( C,D & E are more 3 subcontractor companies are working).

 

WPS/PQR had been established by Subcontractor C only under the shadow of B.

SO can other subcontractors i.e D & E companies can use the same PQR.

 

please mention the clause no. as per ASME sec. IX, is it QW302 ?

 

Waiting for reply.
