It comprises a series of sheets, by materials or by material families, which: indicate t

11、he 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 f

12、or 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. To define preheating conditions, it recommends ISO TR 17671-2 recomm

13、endations. These conditions depend on the calculation of carbon equivalent, welding energy per unit length, thickness, arc welding process and hydrogen rate in filler metal. It is applicable without restriction for the manufacturing of new parts or for repair. 2 Normative references The following re
