Description
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:
— metal inert gas welding (MIG welding); gas metal arc welding /USA;
— tungsten inert gas welding (TIG welding); gas tungsten arc welding /USA;
— plasma arc welding.
It is not applicable to metallurgical aspects (e.g. grain size, hardness).

适用范围:
本文件规定了铝及铝合金弧焊接头的缺欠质量等级。本文件适用于材料厚度为0.5 mm及以上的铝及铝合金。
本文件设定了3个级别的质量等级以适用范围广泛的焊接结构,分别用符号B、C、D表示;质量等级B对应于焊缝的最高质量要求。质量等级与产品质量有关,与所制造产品的适用性无关。
本文件适用于所有接头类型(如对接焊缝、角焊缝和支管连接),手工、机械化和自动化焊接,以及所有焊接位置。
本文件适用于下列焊接方法:
——熔化极惰性气体保护焊(metal inert gas welding,MIG焊);
——钨极惰性气体保护焊(tungsten inert gas welding,TIG焊);
——等离子弧焊(plasma arc welding)。
本文件不适用于冶金缺陷(如晶粒尺寸、硬度)。
