This European Standard specifies the weldability and brazeability of materials or material families used in the aerospace industry. It comprises a series of sheets, by materials or 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 for the welded joint mechanical resistance coefficient for each welding process when extracted from relevant bibliographical references. Joint coefficient is the ratio of stress resistance transversally to welded joint over tensile strength of parent alloy. It recommends ISO/TR 17671-3 and EN 1011-3 for pre-heating conditions specially for the welding of martensitic steels. These conditions depend on the line energy of welding, thickness, arc welding process and of hydrogen rate in filler metal. It applies unreservedly to the manufacturing of new parts or for repair.
