<p>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.</p>
<p>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.</p>
<p>This document is applicable all types of weld (e.g. butt welds, fillet welds and branch connections), to, manual, mechanized and automatic welding, and to all welding positions.</p>
<p>It is applicable to the following welding processes:</p>
<p>- metal inert gas welding (MIG welding); gas metal arc welding /USA;</p>
<p>- tungsten inert gas welding (TIG welding); gas tungsten arc welding /USA;</p>
<p>- plasma arc welding.</p>
<p>It is not applicable to metallurgical aspects (e.g. grain size, hardness).</p>
