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 these shall apply. This standard applies to the arc welding of steels. 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; - all weld metal bend test; - Charpy V-notch impact test; - yield strength or 0,2 % proof stress; - elongation; - chemical analysis; - micro examination; - delta ferrite determination in austenitic stainless steels. Arc welding is covered by the following processes in accordance with EN 24063: 111 - metal-arc welding with covered electrode; 114 - flux-cored wire metal-arc welding without gas shield; 121 - submerged arc welding with wire electrode;1) 122 - submerged arc welding with strip electrode;1) 131 - metal-arc inert gas welding (MIG welding); 135 - metal-arc active gas welding (MAG welding); 136 - flux-cored wire metal-arc welding with active gas shield; 141 - tungsten inert gas arc welding (TIG welding); 15 - plasma arc welding; other fusion welding processes by agreement e.g. metal cored wire arc welding. 1.
