BS EN ISO 17653:2012

This standard BS EN ISO 17653:2012 Resistance welding. Destructive tests on welds in metallic materials. Torsion test of resistance spot welds is classified in these ICS categories:

• 25.160.40 Welded joints and welds

This International Standard specifies specimen dimensions, testing equipment and the procedure for torsion testing of resistance spot welds with single sheet thicknesses ranging from 0,5 mm to 6,0 mm in steels. It can be used for non-ferrous materials in certain circumstances.

The aim of this International Standard is to determine the weld diameter and the failure type of fractured specimens, and to evaluate the influence of different steel types, welding parameters and other factors on the deformation characteristics of a resistance spot weld.
