ISO 15614-12:2004

Specification and qualification of welding procedures for metallic materials — Welding procedure test — Part 12: Spot, seam and projection welding

ISO 15614-12:2004 specifies the tests which may be used for qualification of welding procedure specifications for spot, seam and projection welding processes.

ISO 15614-12:2004 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 International Standard.

Tests shall be carried out in accordance with this International Standard 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 International Standard to other resistance welding processes should be established before any qualification is undertaken.

ISO 15614-12:2004 covers the following resistance welding processes:

- spot welding;

- indirect spot welding;

- direct spot welding;

- seam welding;

- lap seam welding;

- mash seam welding;

- fail butt-seam welding;

- seam welding with strip;

- projection welding;

- indirect projection welding;

- direct projection welding.
