I have one PQR qualified on 6 mm thickness plate(A516 Gr70) with impact test & by GTAW process.Another PQR qualfied on 12 mm plate (A516 Gr 70)with impact test by GTAW+SMAW process. weld metal deposit for 12 mm thick plate was 3 mm (GTAW) & 9 mm(SMAW).
Now I have a job of 10.97 mm thickness which requires impact testing.
Can I develope WPS using GTAW+SMAW process(having above to PQRs as a supporing PQR) for this job.Can 18 mm weld deposit qualification of 12 mm thickness PQR cupon be used here so that I can use the advantage of SMAW welding to maximize the productivity.By this way my thickness range in WPS will be 6 mm to 24 mm.
Is my interpretation per QW200.2(f)is correct??
