ISO 14273:2016 specifies specimen dimensions and a testing procedure for tensile shear testing of spot and embossed projection welds, in overlapping sheets, in any metallic material of thickness 0,5 mm to 10 mm, where the welds have a maximum diameter of 7√t (where t is the sheet thickness in mm). The object of tensile shear testing is to determine the tensile shear force that the test specimen can sustain.

Abstract

Overview

ISO 14273:2016 - Resistance welding - Destructive testing of welds specifies specimen dimensions and a standardized testing procedure for tensile shear testing of resistance spot and embossed projection welds in overlapping metallic sheets. The standard applies to sheet thicknesses from 0.5 mm to 10 mm and covers welds with a maximum diameter of 7√t (t = sheet thickness in mm). The primary objective is to determine the maximum tensile shear force (TSS) that a welded specimen can sustain.

Key topics and technical requirements

Scope and purpose
- Destructive tensile shear testing of spot and projection welds in overlapping sheets to quantify tensile shear strength.
Specimen dimensions and configuration
- Test specimen dimensions are defined by sheet thickness ranges; selected widths in parentheses give approximately a 10% reduction in measured strength and may be used only by mutual agreement.
- The standard includes guidance for producing specimens either from multi-spot test pieces or from individually welded specimens.
- For spot and projection welding, the minimum number of test specimens is eleven.
Weld size limits and saturation
- Applies where weld diameter ≤ 7√t; note that TSS may be underestimated for diameters between 5√t and 7√t using recommended specimen sizes.
- Defines the concept of saturated test specimen size-specimens large enough to measure the maximum (saturated) weld strength.
Test equipment and procedure
- Testing must be performed on a tensile machine that meets ISO 7500-1 (verification/calibration of force-measuring systems).
- Tests are carried out at room temperature.
- Shim plates are required for sheets
