14、O 2004 All rights reserved iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interes
15、ted in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical C
16、ommission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the tech
17、nical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO
18、shall not be held responsible for identifying any or all such patent rights.

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of an identical text or by endorsement, at the latest by February 2005, and conflicting national standards shall be withdrawn at the lates

This standard does not invalidate previous welding procedure qu
32、alifications made to former national standards or specifications provided the intent of the technical requirements is satisfied and the previous procedure qualifications are relevant to the application and production work on which they are to be employed. Also, where additional tests have to be carr
33、ied out to make the qualification technically equivalent, it is only necessary to do the additional tests on a test piece which should be made in accordance with this standard.

34、.ISO 15614-12:2004(E) ISO 2004 All rights reserved 11 Scope 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 E
35、N 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
36、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 app
37、ly. 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.
38、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 te
39、sts; - 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 - s
40、eam welding; 221 - lap seam welding; 222 - mash seam welding; 225 - fail butt-seam welding; 226 - seam welding with strip; SANS 15614-12:2008This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .ISO 15614-12:2004(E) 2 ISO 2004 All rights reserved23
