Spot And Plug Weld Nugget Size: Honda/Acura

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 Honda/Acura has to say.

It is important to note that the Honda/Acura body repair manual (BRM) states in the section Repair Overview - High Strength Steel Sheet Welding Overview - Body Basic, “Spot welding is the recommended and preferred procedure for the welding for high-strength steel parts same as for a mild steel plate welding. In areas that cannot be accessed by a spot welder, perform the MAG welding or MIG brazing as specified in the Replacement procedures.” This section also provides a chart that shows what welding type is allowed on specific tensile strengths (MPa).

Honda/Acura has numerous sections in the (BRM) that address the various types of welding, as well as welding precautions. The following are the sections where you can find specific information on:

  • Spot Welding - Spot Welding Conditions for Ultra High-Strength Steel Parts (1180 & 1500 MPa)- Body Basic: “For spot welds involving 1500MPa steel parts, manual spot welder settings provided in the BRM (or a Honda-specific program) are recommended. Honda does not recommend using the spot welder’s AUTO mode for this steel grade because these settings may not achieve adequate weld strength.”
  • MAG Welding - Plug Welding - Body Basic: This section provides a chart on what size hole will need to be drilled depending on the metal thickness. "To determine the thickness of the parts being welded, refer to the “Body Construction” pages in the “General Information” section of the model specific body repair manual.”

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