Standardi ajalugu
This standard specifies the tests which may be used for qualification of welding procedure specifications. This standard is a part of a series of standards. Details of this series are given in prEN ISO 15607, Annex A. It defines the conditions for carrying out tests and the limits of validity of an qualified welding procedure for all practical welding operations covered by this standard. The tests required to qualify the procedure for a particular component/assembly depend on the performance and quality requirements of the component/assembly and should be defined in the specification. The tests should be carried out in accordance with this standard, unless more severe tests are specified by the relevant application standard or specification, when these should apply. This standard applies to resistance butt welding and flash welding of metallic materials, e. g. with solids, tubular, flat, round cross section. The basic principles of this standard may be applied to other resistance welding processes when this is specified in the specification. NOTE: Specific service, material, or manufacturing conditions may require more comprehensive testing than is specified by this standard. Such tests may include: - Microsections - Fatigue or endurance tests - Impact test - Radiographic test - Ultrasonic test - Corrosion test - Tests of components or complete welded assemblies. This standard covers the following resistance welding processes as defined in EN ISO 4063: 24 - Flash welding using direct current or alternate current with various movement sequences, constant flashing and pulsed flashing. 25 - Resistance butt welding, using direct current or alternate current with various pressure sequences. Other resistance welding processes should be used by agreement, e.g. inductive butt welding.
