EN ISO 15609-5:2004 (E) 4 Introduction All new welding procedures issued and the procedure for their creation and qualification are to be in accordance with this standard for the date of its issue. This standard does not, however, invalidate welding procedures and their qualification complyin
22、g with then existing national or international standards or regulations, provided the intent of the technical requirement is satisfied and the specified application remains unchanged. EN ISO 15609-5:2004 (E) 5 1 Scope This standard specifies requirements for the content of welding procedure specific
23、ations for resistance spot, seam, butt and projection welding processes. The acceptability of applying the principles of the standard to other resistance and related welding processes should be established before any qualification is undertaken. This standard is part of a series of standards. Detail
24、s of this series are given in EN ISO 15607:2003, annex A. Variables listed in this standard are those influencing either weld dimensions (quality), weld nugget dimension, weld pattern positioning, mechanical properties or geometry of the welded joint. 2 Normative references The following referenced
