Thanks Cassgazz. You’ve shed light on something I think is subjective. I believe you are always better to conduct the full range of tests outlined in the applicable standards right from the start. If you need to convert an old procedure to include other welder qualifications not listed and haven’t complied with all the mechanicals and NDT in the PQR, then its time to write a new procedure and commit to the full range of testing outlined in all the applicable standards.
