NOTES:
1/ Test positions for qualification welding are as shown in figure 7-1. The following are the weld positions qualified and they are as defined in AWS A3.0M/A3.0. F = Flat H = Horizontal V = Vertical O = Overhead 2/ Pipe 2-7/8 inch OD and over. Plate fillet welds qualify fillet welds in structural pipe but not socket welds. 3/ Weld test positions for groove welds (e.g., 4G, 5G) shall also apply for surfacing. 4/ Including seal welds as allowed by 5-3.5.2. 5/ In special cases when production welding is to be done in a particular orientation intermediate to those shown in figure 7-1, the welder qualification may, if the organization desires, be made in an intermediate position with the limitation that the qualification shall be valid for the actual position tested with an angle tolerance of +15 degrees in incline to 0 degrees on the flat or horizontal axis. 6/ Tube-to-tubesheet welds shall be qualified in each position to be welded. 7/ Internal tube-to-header welds in boiler components shall be qualified in each position to be welded. 8/ The plasma arc process, using the keyhole technique, must be qualified for each position of welding to be used in production. 9/ When qualifying for welding in the vertical plane in either plate or horizontal fixed-pipe, welding shall be in the up direction. Welding vertical-down shall require separate qualification, except for root passes completely removed, and that for robotic, automatic, and mechanized welding, the 5G position pipe qualification employing 360-degree uninterrupted progression qualifies such progression for the passes involved.
