31、IntroductionIt is intended that all new welding procedure qualifications be carried out in accordance with this part of ISO 15614 from the date of its issue.However, this part of ISO 15614 does not invalidate previous welding procedure qualifications made to other standards or specifications, provid
32、ed the intent of its technical requirements is satisfied and the previous welding procedure qualifications are relevant to the application and production work on which they are to be employed.Also, where additional tests have to be carried out to make the qualification technically equivalent, it is
33、necessary only to perform the additional tests on a test piece made in accordance with this part of ISO 15614.The various parts of ISO 15614 comprise, in their turn, a series of International Standards on welding, details of which are given in ISO 15607, Annex A.vi ISO 2014 All rights reservedBS EN

35、rocedure specifications for spot, seam, and projection welding processes.This International Standard is part of the ISO 15614 series. Details of this series are given in ISO 15607, Annex A.This part of ISO 15614 defines the conditions for carrying out tests and the limits of validity of a qualified
36、welding procedure for all practical welding operations covered by this part of ISO 15614.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 u
37、ndertaken.Tests shall be carried out in accordance with this part of ISO 15614 unless more severe tests are specified by the relevant application standard or contract when these shall apply.The acceptability of applying the principles of this part of ISO 15614 to other resistance welding processes s
38、hould be established before any qualification is undertaken.NOTE Specific service, material, or manufacturing conditions might require more comprehensive testing than is specified by this part of ISO 15614.Such tests can include: method for fatigue testing for spot welded joints; specimen dimensions
39、 and procedure for impact, shear and cross-tension testing resistance spot and projection welds; bend test; surface crack detection; ultrasonic tests and X-ray test; chemical analysis and corrosion tests; micro examination, including assessment of hot cracking behaviour; tests of components or compl
40、ete welded assemblies.This part of ISO 15614 covers the following resistance welding processes, as defined in ISO 4063: 21 resistance spot welding; 211 indirect spot welding; ISO 2014 All rights reserved 1BS EN ISO 15614-12:2014ISO 15614-12:2014(E) 212 direct spot welding; 22 resistance seam welding
