Resistance Spot Welding
Resistance spot welding joins overlapping metal sheets by applying electrical current and electrode pressure at localized contact points. It is widely used in automotive manufacturing, sheet metal assemblies, electrical enclosures, and repeat production of thin metal components.

Manufacturing overview
Resistance spot welding generates heat through electrical resistance at the interface between overlapping workpieces.
The process uses electrodes to apply force and conduct current through the joint.
Common materials include low-carbon steel, galvanized steel, stainless steel, and selected aluminum alloys with suitable equipment.
Typical applications include automotive body structures, sheet metal enclosures, industrial cabinets, brackets, and fabricated assemblies.
The process is particularly suitable for repetitive sheet metal joints where access is available from both sides.
Critical requirements include sheet thickness, electrode accessibility, spot spacing, joint overlap, material coating, and required weld strength.
Buyers should provide assembly drawings, material specifications, spot weld locations, quantities, and applicable acceptance criteria.
Quality control may include visual inspection, destructive peel testing, chisel testing, nugget assessment, and process monitoring.
