Specification for resistance spot welding of uncoated and coated low carbon steel
This British Standard specifies procedures for resistance spot welding in the fabrication of assemblies of uncoated and coated low carbon steel comprising two or three thicknesses of metal, where the single sheet thickness of the components to be welded is within the following ranges:
Guidance on the choice of appropriate welding equipment and approximate spot welding conditions is given in annexes A and B respectively.
This procedure does not apply to the welding of sheets or plates of dissimilar thickness where the thickness ratio is greater than 3 to 1.
In addition to the definitive requirements, this standard also requires the items detailed in clause 4 to be documented. For compliance with this standard, both the definitive requirements and the documented items have to be satisfied.
