4.2 Welding positions and allowable deviations for testing Welding positions used during welding of a test piece shall not exceed +5° in slope and +10° in rotation from the main welding position.
4.3 Welding positions and ranges in production The main welding positions are referenced in other standards, e.g. the ISO 9606 series for qualification of welders, and the ISO 15614 series for qualification of welding procedures. For production welding, the allowable deviations from the main positions used for qualification of welders and welding procedures are given in Table 1 for butt welds and in Table 2 for fillet welds (see also examples in Annex A]. Application standards may extend or restrict the ranges qualified, e.g. an application standard could limit PA to 15° of face rotation rather than 30°. NOTE For asymmetric tolerances,‘’plus” means revolving the weld surface towards the main welding position PA and“minus” means revolving the weld surface towards the main welding position PE. When a test piece is welded using a position outside of the limits (see 3.3) of the main welding positions, the slope and rotation shall be recorded in accordance with Clause 5. The allowable range in production shall be +15° in slope and in rotation.
5 Designation Main welding positions shall be designated by the appropriate symbol in accordance with Figure 1 and Figure 2 (see EXAMPLE 1). The symbol for the main welding position may be supplemented by the values for slope and rotation, given in three digits (see EXAMPLE 2). When a test piece is welded in a position outside of the limits of the main welding positions, the allowable range in production is +15° in slope and in rotation. These supplementary values are mandatory when the test piece used for qualification was outside of the slope and rotation limits specified in 4.2. For circumferential welds in pipes with inclined axes, the indication of slope and rotation shall be simplified in accordance with Figure 2 (see EXAMPLES 3 and 4). EXAMPLE1 The main welding position“horizontal vertical” (PB] is: PB This is a standard test position and the range qualified is in accordance with Table 2. EXAMPLE 2 The main welding position “horizontal vertical” (PB], with slope of 15° and rotation of 10°, is: PB 015-010 This is a special position for which the range qualified is from 0° to 30° of slope and -5° to 25° of face rotation unless specified otherwise in the application standard.
