Steel Spot And Plug Weld Nugget Size: Hyundai - UPDATE
I-CAR · April 8, 2021 · Hyundai
Summary
This article outlines Hyundai's specific welding requirements, noting that while Hyundai does not specify a exact spot or plug weld nugget size, they provide strict guidelines on weld placement, panel thickness limits, and hole diameters. It highlights the requirement to increase the number of spot welds by 30% compared to the factory count and to perform test welds on identical scrap material before repairing the vehicle.
What to do on the job
Perform a test weld on scrap material of the same type and thickness prior to welding, and increase the number of spot welds by 30% (1.3 times the original count) when spot welding.
How to use it
Use this document to justify the additional labor time required for performing mandatory pre-repair test welds (destructive weld testing) and for adding 30% more spot welds than the original factory count as explicitly mandated by Hyundai's body repair manuals.
