Weld-Through Primer Guidelines: Kia

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 Kia recommends and where this information can be found.

Information can be found in the vehicle-specific body repair manual. Kia:

  • calls for applying zinc corrosion inhibitor for welding in most part replacement procedures.
  • does not specify a particular type of weld-through primer.

Use the vehicle-specific body repair manuals 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.
