Welding - Arc-welded joints in aluminium and its alloys - Quality levels for imperfections (ISO 10042:2005); English version of DIN EN ISO 10042:2006-02
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 of the product manufactured.
This International Standard applies to:
-- all types of weld, e.g. butt welds, fillet welds and branch connections;
-- the following welding processes and their sub-processes as defined in 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, mechanized and automatic welding;
-- all welding positions.
Metallurgical aspects, e.g. grain size, hardness, are not covered by this International Standard.
