<p>This document specifies procedures for assessing the generic weldability for resistance spot, seam and projection welding of uncoated and coated metals.</p>
<p>The purpose of the tests described in this document are to</p>
<p>a) compare the metallurgical weldability of different metals,</p>
<p>b) assess the weldability of differing component designs, e.g. dimensional configuration, stack-up, projection geometry, etc.,</p>
<p>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</p>
<p>d) compare the performance of resistance welding equipment.</p>
<p>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.</p>
