Welding and allied processes - Welding positions (ISO 6947:2011); German version EN ISO 6947:2011
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.*This International Standard specifies welding positions for testing and production, for butt and fillet welds, in all product forms. This edition also specifies positions for production welding. Unlike testing positions, these positions are contiguous. Welds of all types and in all directions are covered by this standard. Two annexes provide information about the limits of the slope of a weld axis and the rotation of the weld face about the weld axis for welding positions, and, on the basis of CEN/TR 14633, a comparison of International, European and US designations. The International Standard has been prepared by ISO/TC 44 "Welding and allied processes", in collaboration with CEN/TC 121 "Welding", the secretariat of which is held by DIN. The responsible German Committee is Working Committee NA 092-00-06 AA "Darstellung und Begriffe (DVS AG I 4)" ("Representation and terms (DVS AG I 4)") at NAS. DIN 33946 This standard specifies requirements for the sound pressure level and durability, as well as the appropriate method of measurement for bells, that are fixed to bicycles and to certain types of bicycles with auxiliary engine. This standard (DIN 33946:2009) has been prepared by German Working Committee NA 112-06-02 AA "Fahrrad-Zubehör" ("Accessories for bicycles") of the Sports Equipment Standards Committee (NASport) at DIN.
