Saldim me rezistencë - Prova e fortësisë Vickers (forcë e ulët dhe mikrofortësi) e pikës me rezistencë, projeksionit, dhe tegelave të saldimit (ISO 14271:2017)

Resistance welding - Vickers hardness testing (low-force and microhardness) of resistance spot, projection, and seam welds (ISO 14271:2017)

Scope

ISO 14271:2017 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.
