Description of 20/30374017 DC 2020

This document gives guidance on levels of imperfections in electron and laser beam welded joints in aluminium and its 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 of the product manufactured.

This document applies to electron and laser beam welding of:

  • aluminium and its alloys;

  • magnesium and its alloys;

  • pure copper (e.g. Cu-ETP1 CW003A, Cu-ETP CW004A, Cu-FRHC CW005A, Cu-FRTP CW006A, Cu-OF1 CW007A, Cu-OF CW008A, Cu-OFE CW009A, Cu-PHC CW020A, Cu-HCP CW021A, Cu-PHCE CW022A, Cu-DLP CW023A, Cu-DHP CW024A);

  • all types of welds welded with or without additional filler wire;

  • materials equal to or above 0,5 mm thickness for electron and laser beam welding.

When significant deviations from the joint geometries and dimensions stated in this standard are present in the welded product, it is necessary to evaluate to what extent the provisions of this standard can apply.

NOTE 1

For circular welds, a lower quality level e.g., may be specified for the fade‑out zone.

Metallurgical aspects, e.g. grain size, hardness, hydrogen embrittlement (pure copper) are not covered by this standard.
