You are correct, according to welding procedure qualifications the
tensile test should met the minimum specified tensile strength in the
applicable material specification, in this case BS EN 10225, and not
the actual value mentioned on material certificate. For PQR Cross Weld
tensile specimens are tested and they also can break in the weld metal
but the minimum value which they should reach is in this case 500 MPa.
So yes the PQR should be accepted with the value of 550 MPa.
