ISO 18278-1:2022

<p>ISO 18278-1:2015 specifies procedures for assessing the generic weldability for resistance welding of uncoated and coated metals.</p> <p>It is assumed for this and other linked standards that their application is entrusted to appropriately trained, skilled, and experienced personnel.</p> <p>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.</p> <p>The purpose of the tests 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 will depend on which aspect of items a) to d) will be evaluated relative to the welding result obtained.</p>
