In D1.1 table 4.9 for welder qualifications, the positions listed for groove welds are 1G, 2G, 3G, 4g, and 3G + 4G. So what exactly is 3G + 4G? Does D1.1 define a specific weld procedure on a single test coupon or do you need to run (2), (1) for 3G and (1) for 4G? We already ran the tests for the welder qualification as follows:
Position: 3G - (1) CJP Groove test per D1.1 with 3/8" thk. coupons to qualify 1/8" - 1/2" (E71T-11 electrode, per Table 3.1, -11 suffix shall be excluded for thicknesses greater than 1/2") in the F,H, V positions
4G - (1) CJP Groove test per D1.1 to qualify same thickness in F, OH positions
Since there were two tests, and I did not know the guidelines for the 3G + 4G qualification test, I wrote (2) WQRs, (1) for the 3G and (1) for the 4G to qualify all positions between the two. Should I have written (1) WQR for the 3G + 4G instead? There was some confusion when the on-site weld inspector looked at the WQRs because he looked at the 4G WQR and the welder was currently welding in the 3G (up) position. He halted the welder and stated that according to our WQRs the welder could not perform that weld. Instead of flipping one page back and seeing that the 3G position had been qualified he raised a big stink.
Should I have written the WQR differently to avoid this? Let me know your thoughts . . . thanks!
