Resistance welding — Testing of welds — Peel and chisel testing of resistance spot and projection welds

This document specifies the procedures and recommended tooling to be used for peel and chisel testing of resistance spot and embossed projection welds. This document applies to welds made in two or more sheets in the thickness range of 0,5 mm to 3,0 mm.

The aim of these tests is to determine:

—    weld size and failure mode when welds are destructively tested;

—    verification of welds by non-destructive chisel tests.

NOTE      The preferred method of peel testing seam welds (mechanized peel testing) is covered in ISO 14270.
