Steel Spot And Plug Weld Nugget Size: Honda/Acura - UPDATE
I-CAR · December 4, 2019 · Honda, Acura
Summary
This document outlines Honda/Acura welding guidelines, establishing squeeze-type resistance spot welding (STRSW) as the preferred repair method to maintain factory strength. It highlights that while Honda does not specify a exact nugget size, technicians must manually set spot welders for 1500 MPa steel instead of using AUTO mode, and must size plug weld holes according to the metal thickness chart in the Body Repair Basic manual.
What to do on the job
Do not use the spot welder's AUTO mode when welding 1,500 MPa ultra-high-strength steel; instead, use manual settings or a Honda-specific program, and size plug weld holes according to the metal thickness chart in the Body Repair Basic manual.
How to use it
Use this document to justify the time and equipment setup required for manual spot welder programming when working on 1500 MPa steel, and to defend the necessity of researching metal thicknesses in the 'Body Construction' section to determine correct plug weld hole sizes.
