Back-To-Basics: Using The Correct Spot Welding Tips
I-CAR · July 17, 2020
Summary
This article emphasizes the critical role of selecting the correct spot welding electrode tips (flat, dome, or OEM-specified) to ensure proper heat distribution and weld penetration. Using incorrect tips can lead to weak welds, excessive heat that damages high-strength steels, or incorrect weld sizes, ultimately compromising the structural integrity of the repair.
What to do on the job
Perform test welds using the OEM-specified electrode tips to verify proper penetration and weld size before performing production spot welds on the vehicle.
How to use it
Use this document to justify the time and materials required for performing mandatory test welds and to support the necessity of sourcing OEM-specified welding tips/electrodes as dictated by the vehicle-specific repair manual.
