11、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 weldi

12、ng 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 coe

13、fficient 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. 2 Normative references The following referenced documents are indispensable for the applicati

23、 structure, is given in Clause 6 in this standard. The degree of weldability or brazeability to be used is the value indicated by the material sheet considered for the process chosen. In the operating cycle, choose thermal states that give the lowest degree in preference. If two degrees are indicate

24、d, the responsible person must select the degree that is most appropriate for the definition of the assembly. 5 Updating this standard See EN 4632-001. 2) Published by: AWS, 550 N.W.
