BS EN ISO 18595:2007

BS EN ISO 18595:2007 Resistance welding. Spot welding of aluminium and aluminium alloys. Weldability, welding and testing BS EN ISO 18595 is the international standard that specifies the requirements for resistance spot welding in the fabrication of assemblies of aluminium sheet, extrusions (both work- and age-hardening alloys) and/or cast material comprising two or three thicknesses of metal, where the maximum single (sheet) thickness of components to be welded is within the range 0,6 mm to 6 mm. BS EN is applicable to the welding of sheets or plates of dissimilar thickness where the thickness ratio is less than or equal to 3:1. It applies to the welding of three thicknesses where the total thickness is less than or equal to 9 mm. Welding with the following types of machines is within the scope of this BSENISO18595:
