Welding Procedure Specification
Welding Procedure Specification
(OP)
I am a bit confused, in the summer edition of IT magazine the author said a common mistake is to list the positions as 1G,2G, 3G and 4G instead of F,V,H and OH. on WPS and PQR. Under Figure 4.3(see 4.3.4) Positions of Test Plates for groove welds it lists 1G Flat, 2G Horizontal, 3G Vertical and 4G overhead. 4.3.4 Positions of Welds. All welds shall be classified as flat(F), horizontal(H), vertical(V), and overhead(OH), in conformance with the definitions shown in Figures 4.1 and 4.2. Is there a difference? Is it a mistake?

The position that 1F, 2F, 3F, 4F, and 1G, 2G, 3G, and 4G are test positions.
