ISO 18595:2007

ISO 18595:2007 specifies 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. ISO 18595:2007 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 ISO 18595:2007: pedestal welding machines; gun welders; automatic welding equipment where the components are fed by robots or automatic feeding equipment; multi-welders; robotic welders. The welding of coated material, e. g. zinc coated or anodised material, is not within the scope of ISO 18595:2007.
