Widerstandsschweißen - Schweißeignung - Teil 1: Allgemeine Anforderungen an die Bewertung der Schweißeignung von Widerstandspunkt-, Rollennaht- und Buckelschweißen von metallischen Werkstoffen (ISO 18278-1:2015); Deutsche Fassung EN ISO 18278-1:2015
Overview
This International Standard specifies the procedures for assessing the generic weldability for resistance welding of uncoated and coated metals. It is assumed for this and other linked standards that their application is entrusted to appropriately trained, skilled, and experienced personnel. For the quality of welded structures, the relevant part of ISO 14554 is applicable. The specification of procedures is to follow guidelines as in ISO 15609-5. The purpose of the tests are to: a) compare the metallurgical weldability of different metals and/or b) assess the weldability of differing component designs, for example dimensional configuration, stack-up, projection geometry, etcetera and/or c) investigate the effect of changes in welding parameters such as welding current, weld time, electrode force or complex welding schedules including pulse welding, current stepping etcetera on weldability and/or d) compare the performance of resistance welding equipment. Precise details of the test procedure to be used will depend on which aspect of items a) to d) will be evaluated relative to the welding result obtained.
