Specification and approval of welding procedures for metallic materials - Part 4: Welding procedure tests for the arc welding of aluminium and its alloys
This standard specifies how a welding procedure specification is approved by welding procedure tests. It defines the conditions for the execution of welding procedure approval tests and the limits of validity of an approved welding procedure for all practical welding operations within the range of variables listed in clause 8. Tests shall be carried out in accordance with this standard unless more severe tests are specified by the relevant application standard or contract, when they shall be applied. This standard applies to the arc welding of wrought aluminium and its weldable alloys according to EN 515 1) and EN 573-3 1). In this standard the term aluminium stands for aluminium and its alloys. The principles of this standard may be applied to other fusion welding processes subject to agreement between the contracting parties. Note: Specific service, material or manufacturing conditions may require more comprehensive testing than is specified by this standard in order to gain more information and to avoid repeating the welding procedure test at a later date just to obtain additional test data. Such tests may include: - longitudinal weld tensile test; - weld bend test or special bend test to measure elongation; - Charpy V-notch impact test; - 0,2 % proof stress; - elongation; - chemical analysis. Arc welding is covered by the following processes in accordance with EN 24063:1) 131 - metal-arc inert gas welding (MIG welding); 141 - tungsten inert gas arc wedling (TIG welding); 15 - plasma arc welding; other fusion welding processes by agreement. 1. The reference was modified by Amendment A1 :1997
Anforderung und Anerkennung von Schweißverfahren für metallische Werkstoffe - Teil 4: Schweißverfahrensprüfungen für das Lichtbogenschweißen von Aluminium und seinen Legierungen
Diese Norm legt fest, wie eine Schweissanweisung durch eine Schweissverfahrensprüfung anerkannt wird. Sie erklärt die Bedingungen für die Durchführung der Schweissverfahrensprüfung und die Grenzen der Gültigkeit eines anerkannten Schweissverfahrens für alle praktischen schweisstechnischen Tätigkeiten innerhalb des Bereiches der Einflussgrössen nach Abschnitt 8.
