Resistance welding. Vickers hardness testing (low-force and microhardness) of resistance spot, projection, and seam welds Ingestion-build-67170 but may be used for1 Scope This document specifies the procedures for the hardness testing of etched cross sections of resistance spot, projection, and seam welds. The aim of the hardness tests is to determine the Vickers hardness, in the low force or microhardness range, of the weld nugget, the heat affected zone, and parent material in ferrous or non ferrous metals for welds made in sheets of thickness 0,5 mm to 6 mm.
