AWS D1.1 Welding Qualification

By Victorio Date 09-24-2008 09:07

Reference: AWS D1.1 Table 4.1 - PQR done in 3G (plate) could only qualify Vertical position in production welding.
Case: Supporting PQR is done in 3G position. The contractor would like to support this for WPS which the contractor intend to qualify it(WPS) for ALL position. The contractor proposed to accept the WPS (all position) with PQR in 3G only with a suggestion that the qualification of welder will be done in 2G, 3G and 4G position.

Can this proposal be acceptable?

The welding procedure must be tested in the other two positions as indicated by table 4.1. Since the welder needs to qualify in all positions, let him weld the PQR for the 2G and 4G.

I agree. I wouldn't accept it.
