Destructive tests on welds in metallic materials - Torsion test of resistance spot welds (ISO 17653:2003) EN ISO 17653:2003

Publication date:   Aug 10, 2006

Scope

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.
