Yes, you can, provided all essential/supplementary essential variables are identical to original  PQR.

Subject: [MW:0] Supporting PQR for Impact requirements

 

Dear All, 

 

I have Qualified PQR for welding P1 Gr 1 To P1 Gr 1 with Impact test at (-) 51°C 

thickness range 2.77 to 11.08 mm.

But now we have to weld P1 Gr 1 to P1 Gr 2. Can I do one more supporting PQR with with P1 Gr 1 to P1 Gr 2 With only impact testing.

Please clarify whether Tensile test and bend test are mandatory for supporting  PQR.

 

 

Thanking you.
