Welding and allied processes - Welding positions (ISO 6947:2019); German version EN ISO 6947:2019
The direction of welding is an essential parameter for determining the welding 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 in all types and all directions are covered. The main positions have been given symbols which can easily be used for designation purposes; these symbols were chosen independently of possible meaningful abbreviations, i.e. they are not derived from any particular language. This standard provides positions for standard discreet test piece orientation PA, PB, H-L045, etc. that have been contained by this standard since its inception. In this revision, positions are defined for production welding. These positions are flat, horizontal, vertical and overhead and unlike test positions, these positions are contiguous. The relationship between test positions and production welding positions is specified in other standards such as ISO 9606 or ISO 15614.
