Specification and qualification of welding procedures for metallic materials — Welding procedure test — Part 13: Upset (resistance butt) and flash welding

Апстракт

This document 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 document defines the conditions for carrying out tests and the limits of validity of a qualified welding procedure for all the practical welding operations that it covers.
It 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 upset welding, using direct current or alternating current with various pressure sequences.
