ISO 10042:2005 specifies quality levels for imperfections in arc-welded joints in aluminium and its alloys. It applies to material thicknesses above 0,5 mm. It covers full-penetration butt welds and all fillet welds. The principles of the standard may also be applied to partial-penetration butt welds.
Three quality levels are given in order to permit application to a wide range of welded constructions. The quality levels refer to production quality and not to the fitness for purpose of the product manufactured.
The 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 the standard.
