Table QW-461.9 is for Performance Qualification. A welder who passes a qualification test in the 2G, 3G, and 4G is qualified to weld plate, and pipe over Ø24" in all positions. Pipe Ø2-7/8 OD and Ø24" and under is qualified for Flat and Horizontal only.
QW-203, Unless specifically required otherwise by the welding variables (QW-250), a qualification in any position quaifies the "procedure" for all position.........................A welder or welding operator making and passing the WPS qualification test is qualified for the position tested.
QW-405.2 is a supplementary essential variable for Procedure Qualification when notch toughness tests are required. If a procedure is qualified in the 3G, 5G, or 6G positions using a uphill progression, the procedure does not need to be requalified for other positions unless there is a change from Stiringers to Weaves.
If a procedure is qualified in the 1G, 2G, or 4G positions, another qualification would be required if a vertial up (3G) was needed, that had notch toughness test requirements.
