Arc-welded joints in aluminium and its weldable alloys - Guidance on quality levels for imperfections (ISO 10042:1992)

Publication date:   Jun 19, 2000

Scope

This International Standard provides guidance on levels of imperfections in arc-welded joints in aluminium and its weldable alloys. Three levels are given in such a way as to permit application for a wide range of welded fabrications. The levels refer to production quality and not to the fitness-for-purpose (see 3.1) of the product manufactured. This International Standard applies to: - aluminium and weldable aluminium alloys; - the following welding processes in accordance with ISO 4063: 131 gas-shielded metal-arc welding (MIG); 141 gas-shielded welding with non-consumable electrode (TIG); 15 plasma arc welding. - manual, mechanized and automatic processes; - all welding positions; - butt welds, fillet welds and branch connections; - materials in the thickness range 3 mm to 63 mm. When significant deviations from the joint geometries and dimensions described in this International Standard are present in the welded product, it is necessary to evaluate to what extent the provisions of this standard can apply. Metallurgical aspects, e.g. grain size, hardness, are not covered by this International Standard.
