Aerospace series - Welded and brazed assemblies for aerospace constructions - Weldability and brazeability of materials - Part 002: Homogeneous assemblies aluminium and aluminium alloys; German and English version EN 4632-002:2008
This standard defines degrees of weldability and brazeability for materials or families of materials used in the
aerospace industry.
It comprises a series of sheets, by materials or by material family which:
-- indicate the main titles, the typical chemical composition and the main characteristics,
-- contain recommendations for welding and brazing,
-- indicate a degree of weldability or brazeability for a given process under defined conditions.
-- indicate a value of the mechanical strength coefficient of the welded joint for each welding process, when
it could be extracted from bibliographic references referring to it. The joint coefficient is expressed as a
ratio of the tensile strength of the welded joint to the tensile strength of the base alloy.
It is applicable without restriction for the manufacturing of new parts or for repair.
