DIN EN 4632-003:2010-09

This standard defines degrees of weldability and brazeability for unalloyed and low alloy steels used in the aerospace industry. It comprises a series of sheets, by materials or by material families, 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. This document is applicable without restriction for the manufacturing of new parts or for repair. The standard EN 4632-003:2010 has been prepared by ASD-STAN, Technical Section Metallic Materials. The responsible German standardization committee is Working Committee NA 092-00-17 AA "Schweißen im Luft- und Raumfahrzeugbau (DVS AG A 9)" ("Welding in aerospace (DVS AG A 9)") of the Welding Standards Committee (NAS).
