Widerstandsschweißen - Zerstörende Prüfung von Schweißverbindungen an metallischen Werkstoffen - Torsionsversuch an Widerstandspunktschweißverbindungen (ISO 17653:2012); Deutsche Fassung EN ISO 17653:2012
Overview
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 the test 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 with values of the maximum torque and the associated torsion angle. The document (EN ISO 17653:2010) has been prepared by Technical Committee ISO/TC 44 "Welding and allied processes", SC 6 "Resistance welding and allied mechanical joining" (secretariat: DIN), in collaboration with CEN/TC 121 "Welding", the secretariat of which is held by DIN. Joint Working Committee NA 092-00-12-07 AK "Prüfen von Widerstandsschweißverbindungen (DVS AG V 3.9)" ("Testing of resistance-welded joints (DVS AG V 3.9)") of the Welding Standards Committee (NAS) at DIN is responsible for this standard.
