NF EN ISO 17653
Destructive tests on welds in metallic materials - Torsion test of resistance spot welds
ISO 17653:2003 is applicable to spot welded test specimens with single sheet thicknesses ranging from 0,5 mm to 3,0 mm in steels. It may be used for non-ferrous materials in certain circumstances. The aim of this test is to determine the influence of different steel types, welding parameters and other factors on the deformation characteristics of a spot weld. Using this test, it is possible to determine the weld diameter and the fracture type from fractured specimens. Additionally, the maximum torsion moment (torque) and the corresponding torsion angle can be determined.

<p>1 Scope</p> <p>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.</p> <p>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.</p>
