ISO 15614-13:2005 specifies the tests which should be used for qualification of welding procedure specifications.

It applies to resistance butt welding and flash welding of metallic materials, e.g. with solid, tubular, flat or circular cross-section. The basic principles of ISO 15614-13:2005 may be applied to other resistance welding processes when this is specified in the specification.

ISO 15614-13:2005 defines the conditions for carrying out tests and the limits of validity of a qualified welding procedure for all practical welding operations covered by ISO 15614-13:2005.

ISO 15614-13:2005 covers the following resistance welding processes as defined in ISO 4063:

24 flash welding using direct current or alternating current with various movement sequences, constant flashing and pulsed flashing;

25 resistance butt welding, using direct current or alternating current with various pressure sequences.
