2Scope / Description
This document defines the tests applicable for qualifying welding procedure specifications for spot, seam, and projection welding processes. NOTE: Procedures for relief projection welding are documented; these may also be adapted for solid-phase projection processes, such as nut welding, pin welding, and cross-wire welding. This document specifies the conditions for conducting tests and the validity scope of qualified welding procedures for all practical welding operations covered herein. It addresses the following contact welding processes, as defined in ISO 4063: — 21: spot welding; — 211: indirect spot welding; — 212: direct spot welding; — 22: seam welding; — 221: lap seam welding; — 222: mash seam welding; — 223: prep-lap seam welding; — 224: wire seam welding; — 225: foil butt-seam welding; — 226: seam welding with strip; — 23: projection welding; — 231: indirect projection welding; — 232: direct projection welding.
