This International Standard specifies requirements for resistance seam welding in the fabrication of
assemblies of uncoated and metallic coated low carbon steel comprising two sheets of metal, where the maximum single sheet thickness of components to be welded is within the range 0,4 mm to 3 mm for the following materials:
. uncoated steels;
. hot-dip zinc or iron-zinc alloy (galvannealed) coated steel;
. electrolytic zinc, zinc-iron, or zinc-nickel coated steel;
. aluminium coated steel;
. zinc-aluminium coated steel.
Organic-coated or primer-coated steels are not covered by this International Standard. Guidelines for the design of appropriate seam welding equipment and welding conditions are given in Annexes A and B. These are for guidance only and may need to be adapted to suit the specified service conditions of the fabrication, prevailing production conditions, type of welding equipment, mechanical and electrical characteristics of the welding machine, electrode configuration, and material. These requirements shall be taken from the relevant welding procedure specification for the application or procedure, where these exist.
