Anotace textu normy ČSN EN ISO 15614-12   (050313)

This document specifies the tests which can be used for qualification of welding procedure specifications for spot, seam, and projection welding processes.

NOTE - The procedures are written for embossed projection welding. They can be adapted for solid projections as well, e.g. nut welding, stud welding. cross wire welding.

This document 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 document.

It covers the following resistance welding processes, as defined in ISO 4063:

- 21 - resistance spot welding,

- 211 - indirect spot welding,

- 212 - direct spot welding,

- 22 - resistance 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.
