This document specifies procedures for assessing the generic weldability for resistance spot, seam and projection welding of uncoated and coated metals. The purpose of the tests described in this document are to a) compare the metallurgical weldability of different metals, b) assess the weldability of differing component designs, e.g. dimensional configuration, stack-up, projection geometry, etc., 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 etc. on weldability, and/or d) compare the performance of resistance welding equipment. Precise details of the test procedure to be used depend on which aspect of items a) to d) will be evaluated relative to the welding result obtained.
