Specification and qualification of welding procedures for metallic materials. Welding procedure test - Upset (resistance butt) and flash welding Ingestion-build-81500 b) for flanged end1 Scope This part of ISO 15614 specifies tests for the qualification of welding procedure specifications applicable to upset (resistance butt) welding and flash welding of metallic materials, e. g. with solid, tubular, flat or circular cross section. Its basic principles can also be applied to other resistance welding processes when this is stated in the specification. This part of ISO 15614 defines the conditions for carrying out tests and the limits
