Spot And Plug Weld Nugget Size: FCA/Stellantis

Spot And Plug Weld Nugget Size: FCA/Stellantis

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 FCA/Stellantis has to say.

FCA/Stellantis provides a Minimum Weld Nugget Requirement Chart within vehicle-specific body repair manuals. This chart provides the governing metal thickness (GMT) and the minimum weld nugget diameter to help ensure a solid weld. Beneath the chart is a detailed description of GMT and how it is to be determined when welding more than three panels together.

Per the FCA/Stellantis Collision Bulletin, Welded Sheet Metal Repairs and Replacements:
“The replacement STRSW welds should duplicate the original welds in size, quantity, and location.” If spot-welder arms are unable to reach, vehicle-specific body repair manuals state, “Welding of structural panels through 3 or more tiers of panel stack ups will require 9.5 mm plug welds. Exterior panels should be installed using 8 mm plug welds.”

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