Widerstandsschweißen - Zerstörende Prüfung von Schweißverbindungen - Probenmaße und Verfahren für die mechanisierte Schälprüfung an Widerstandspunkt-, Rollennaht- und Buckelschweißungen mit geprägten Buckeln (ISO 14270:2016); Deutsche Fassung EN ISO 14270:2016
Overview
This International Standard specifies specimen dimensions and a testing procedure for mechanized peel testing of single spot, seam and embossed projection welds, in overlapping sheets, in any metallic material of thickness 0,5 mm to 3 mm, where the welds have a maximum diameter of 7·root t (where t is the sheet thickness in mm). For welds of diameter between 5·root t and 7·root t, the peel strength values obtained may be lower than expected when using the recommended test specimen dimensions because the test specimen width is designed for welds of diameter of 5·root t or less. The object of mechanized peel testing is to determine the peel strength that the test specimen can sustain. The committee responsible for this standard is NA 092-00-12 AA "Widerstandsschweißen (DVS AG V 3)" ("Resistance welding (DVS AG V 3)") at DIN Standards Committee Welding and allied processes (NAS).
