DIN EN ISO 6947:2011-08 EN ISO 6947:2011 (E) 3 Introduction This International Standard provides positions for standard discrete test piece orientation PA, PB, H-L045, etc. that have been specified in this International Standard si
21、nce the first edition (ISO 6947:1980). In this revision, positions are defined for production welding. These positions are flat, horizontal, vertical, and overhead. Unlike testing positions, these positions are contiguous. The direction of welding is an essential parameter for determining the weldin
22、g position, e.g. up or down. The welding position is not dependent on the geometrical arrangement of the joint, e.g. butt or fillet joint, or that of the semi-finished product. Welds of all types and in all directions are covered. The main positions have been given symbols which can easily be used f
23、or designation purposes; these symbols were chosen independently of possible meaningful abbreviations, i.e. they are not derived from any particular language. The relationship between testing positions and production welding positions is specified elsewhere, e.g. in ISO 96061or ISO 156142. DIN EN IS
24、O 6947:2011-08 EN ISO 6947:2011 (E) 4 1 Scope This International Standard 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
25、welding positions in production welds. Annex B provides a comparison of International, European and US designations. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 welding position position of a weld in space, which is defined relative to th
26、e slope of the axis and rotation of the face of the weld relative to the horizontal plane 2.2 main welding position welding position, designated PA, PB, PC, PD, PE, PF or PG NOTE For PA, PB, PC, PD and PE, see Figure 1. 2.3 slope S angle of the axis of the weld relative to the main welding position
27、2.4 rotation R angle of the face of the weld relative to the main welding position 2.5 inclined angle L angle of the axis of the pipe 3 Welding positions 3.1 Main welding positions The main welding positions are illustrated in Figure 1 with examples of their application for butt and fillet welds in

34、 ISO 156142, to define the orientation of welds in production welding after qualifying in one of the main welding positions PA, PB, H-L045, etc. Slope and rotation ranges for welding positions in production are given in Table 1 for butt welds and in Table 2 for fillet welds (see also examples in Ann
35、ex A). NOTE For asymmetric tolerances, plus means revolving the weld surface towards the main welding position PA and minus towards the main welding position PE.

The symbol for the main welding position may be supplemented by the values for slope and rotation, given in three digits (see Example 2).
