AS NZS 3545:2020(E) Welding and allied processes一 Welding positions. This document defines welding positions for testing and production, for butt and fillet welds, in all product forms. Annex A gives examples of the limits of the slope of a weld axis and the rotation of the weld face about the weld axis for welding positions in production welds. Annex B gives a comparison of this document and US designation systems for welding positions. 2 Normative references There are no normative references in this document. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: — ISO Online browsing platform: available at https://www.iso.org/obp — IEC Electropedia: available at http://www.electropedia.org/ welding position position of a weld defined relative to the slope of the axis and rotation of the face of the weld relative to the horizontal plane 3.2 main welding position welding position (11) designated PA, PB, PC, PD, PE, PF, PG. PH, PJ or PK Note 1 to entry: See Figure 1 and Figure 2 for welding position designations. 3.3 special test position any welding position (11) that is not covered by one of the main welding positions (3.2) (see 43) 3.4 slope S angle of the axis of the weld relative to the main welding position (3.2) 3.5 rotation angle of the face of the weld relative to the main welding position (32) 3.6 inclined angle angle of the axis of the pipe 4.2 Welding positions and allowable deviations for testing Welding positions used during welding of a test piece shall not exceed ±50 in slope and ±100 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 TabIeI for butt welds and in Table2 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 150 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...
