Weld-Through Primer Guidelines: Hyundai

Weld-through primers are generally a zinc-based product that are applied to the mating surfaces prior to welding. Corroding zinc forms zinc oxide which protects the steel. This is called sacrificial corrosion. For a quality weld to be made it’s required that the weld-through primer be removed from the direct weld zone before welding the joint when GMA welding. Many OEMs have a position on when and how to use weld-through primer or when it shouldn’t be utilized. Let’s see what Hyundai recommends and where this information can be found.

Information can be found within repair procedures in vehicle-specific body repair manuals (BRMs). Hyundai calls for "zinc corrosion inhibitor for welding" when replacing a body panel. Hyundai does not specify what brand of zinc weld-through primer to be used.

Use the vehicle-specific BRM to determine which type of welding is required for the repair you are performing. Failure to follow OEM procedures will sacrifice the safety and quality of the repair.
