Tube-to-tubesheet PQR/WPS Qualification (mock-up test)

[MBWeld]

Hi All,

I have a PQR (Charpy tested) and a WPS with a qualification range of 3mm to 12mm. My question is: I need to perform tube-to-tubesheet welding—can this PQR/WPS be used to cover the welding, referencing the code for the mock-up test? In that case, is a PWPS required for the mock-up test?

ps client’s spec doesn’t mentioning anything about tube to tubesheet welding apart referring to the code

Thanks
