BS EN ISO 10042:2018 pdf free.Welding一Arc-welded joints in aluminium and its alloys一Quality levels for imperfections
This document specifies quality levels for imperfections in arc-welded joints in aluminium and its alloys. It applies to material thicknesses above 0,5 mm.
Three quality levels are given in order to permit application to a wide range of welded constructions.
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 document is applicable to all types of welds (e.g. butt welds, fillet welds and branch connections),to manual, mechanized and automated welding, and to all welding positions.
It is applicable to the following welding processes:
一metal inert gas welding (MIG welding); gas metal arc welding /USA;
一tungsten inert gas welding (TIG welding); gas tungsten arc welding /USA;
一plasma arc welding.
It is not applicable to metallurgical aspects (e.g grain size, hardness).
