Steel Spot And Plug Weld Nugget Size: Kia - UPDATE
I-CAR · March 18, 2020 · Kia
Summary
This article outlines Kia's specific guidelines for spot and plug welding during collision repairs, noting that while Kia does not specify a precise weld nugget size, they provide detailed requirements for panel thickness, hole diameters, and weld counts. Kia emphasizes using spot welding as the primary method, increasing the spot weld count by 30% compared to factory welds, and performing destructive test welds on identical scrap material before repairing the vehicle.
What to do on the job
When performing structural repairs on Kia vehicles, increase the number of spot welds by 30% compared to the original factory count, and always perform a test weld on identical scrap material of the same type and thickness prior to welding the vehicle.
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. It can also be used to defend the choice of spot welding over plug welding as Kia's preferred, most reliable method.
