This International Standard provides quality levels of imperfections in arc-welded joints in aluminium and its alloys. It applies to material thickness above 0,5 mm. Quality levels for beam welded joints are presented in ISO 13919-2. Three quality levels are given in order to permit application for a wide range of welded fabrication. They are designated by symbols B, C and D. Quality level B corresponds to the highest requirement on the finished weld. The quality levels refer to production quality and not to the fitness-for-purpose (see 3.2) of the product manufactured. This International Standard applies to: - all types of welds, e. g. butt welds, fillet welds and branch connections; - the following welding processes and their defined sub-processes in accordance with ISO 4063: - 131 metal inert gas welding (MIG welding); gas metal arc welding /USA/; - 141 tungsten inert gas welding (TIG welding); gas tungsten arc welding /USA/; - 15 plasma arc welding; - manual, mechanised and automatic welding; - all welding positions. Metallurgical aspects, e.g. grain size, hardness, are not covered by this International Standard. For the purposes of this International Standard the term aluminium covers aluminium and its alloys.
