GB/T 39165-2020Test method of peel and chisel for resistance spot and projection welds (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the redrafting method to modify and adopts ISO 10447.2015 "Testing of resistance welding welds. Resistance spot welding and projection welding joints.

Peeling and chipping test."

Compared with ISO 10447.2015, this standard has many structural adjustments. Appendix A lists this standard and ISO 10447.2015.

3 Terms and definitions

The following terms and definitions defined in GB/T 3375 apply to this document.

3.1

Gouge test

Use a chisel to go between the plates of adjacent solder joints until fracture occurs or the base material near the solder joint yields or bends.

see picture 1.

a) Type 1 (embedded chiseling) b) Type 2 (single-sided chiseling) c) Type 3 (bilateral chiseling)

3.2

Peel test

Destructive test of resistance welding lap joints by applying peeling force in the thickness direction of the solder joints.
