Specification and qualification of welding procedures for metallic materials - Welding procedure test - Part 12: Spot, seam and projection welding (ISO 15614-12:2004)

Status: Withdrawn · Replaced by: SS-EN ISO 15614-12:2014

This standard specifies the tests which may be used for qualification of welding procedure specifications for spot, seam and projection welding processes. This standard is part of a series of standards. Details of this series are given in EN ISO 15607:2003, annex A. This standard defines the conditions for carrying out tests and the limits of validity of a qualified welding procedure for all practical welding operations covered by this standard. The tests required to qualify the procedure for a particular component/assembly depend on the performance and quality requirements of the component/assembly and shall be established before any qualification is undertaken. 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. The acceptability of applying the principles of the standard to other resistance welding processes should be established before any qualification is undertaken. NOTE Specific service, material or manufacturing conditions may require more comprehensive testing than is specified by this standard. Such tests may include: - method for fatigue testing for spot welded joints; - specimen dimensions and procedure for impact, shear and cross tension testing resistance spot and projection welds; - bend test; - surface crack detection; - ultrasonic tests, x-ray test; - chemical analysis; corrosion tests; - micro examination, including assessment of hot cracking behaviour; - tests of components or complete welded assemblies. This standard covers the following resistance welding processes, as defined in EN ISO 4063: 21 - spot welding; 211 - indirect spot welding; 212 - direct spot welding; 22 - seam welding; 221 - lap seam welding; 222 - mash seam welding; 225 - fail butt-seam welding; 226 - seam welding with strip; 23 - projection welding; 231 indirect projection welding; 232 direct projection welding.
