[MW:8853] Welding between A106 Gr.B and API 5L Gr.B

Dear All,

One of my contractor submitted and wps/pqr for approval for welding
between A106 Gr.B and API 5L Gr.B pipes.

The Wps is prepared newly for this project and PQR is from old
projects.

I reviewed and i found that the PQR is done for API 5L PSL1-Gr.B to
API 5L PSL1-Gr.B.

Is it possible to prepare the wps for A106 Gr.B and API 5L Gr.B pipes
based on the above PQR.

Please reply.

Thanks.
