After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received the approval of the National Associations and the
13、 Official Services of the member countries of ASD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2010, and conflicting national standards shall be wit

BS EN 4632-003:2010EN 4632-003:2010 (E) 4 1 Scope This standard defines degrees of weldability and brazeability for materials or families of materials used in the aerospace industr
17、y. It comprises a series of sheets, by materials or by material families, which: a) indicate the main titles, the typical chemical composition and the main characteristics; b) contain recommendations for welding and brazing; c) indicate a degree of weldability or brazeability for a given process und
18、er defined conditions; d) 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 t
19、ensile strength of the base alloy. To define preheating conditions, it recommends EN 1011-2 recommendations. 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 res
20、triction for the manufacturing of new parts or for repair. 2 Normative references The following referenced documents are indispensable for the application of this document.
