Spot And Plug Weld Nugget Size: GM

Spot And Plug Weld Nugget Size: GM

Did you know that many OEMs specify nugget size for spot and plug welds? This information is typically found within vehicle-specific repair procedures or can be found under general welding guidelines. Let’s see what General Motors (GM) has to say.

GM service manuals typically specify that: "Squeeze type resistance spot welds equivalent to the factory spot welds are recommended. If access to use squeeze type resistance spot welds is not possible, MIG/MAG 8 mm (5/16 in) plug welds may be used to replace those specific welds."

This information can be found in vehicle-specific repair procedures as well as the Resistance Spot Welded Full Panel Replacement document.

Follow OEM welding requirements, including what nugget size is required, to help ensure a complete, safe, and quality repair.
