Weld-Through Primer Guidelines: Hyundai
I-CAR · June 22, 2021 · Hyundai
Summary
Hyundai recommends applying a zinc-based weld-through primer (zinc corrosion inhibitor) to mating surfaces prior to welding in areas where epoxy adhesive cannot be applied. Technicians must refer to the vehicle-specific Body Repair Manual (BRM) to identify exact replacement and sectioning procedures where this is required.
What to do on the job
Apply a zinc-based weld-through primer to mating surfaces prior to welding where epoxy adhesive cannot be applied, ensuring the primer is removed from the direct weld zone before GMA welding.
How to use it
Use this document to justify the labor and material costs for applying zinc-based weld-through primer during structural panel replacement or sectioning. Refer to the specific Hyundai Body Repair Manual (BRM) under 'Body Panel Repair Procedure' to prove to insurers that the OEM explicitly requires zinc corrosion inhibitor for welding when epoxy adhesive is not utilized.
