Weld-Through Primer Guidelines: Mazda

Posted on 22 February 2017 | Share: | Print Print

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 Mazda recommends and where this information can be found.

This information, along with other part preparation guidelines, can be found in the vehicle-specific body repair manual under: Bodyshop Manual ➤ General Information ➤ Installation Preparations tab.

  • Mazda recommends the use of weld-through primer.
  • They say to remove any paint, grease, or other material from areas to be welded prior to applying weld-through primer.
  • Mazda does not recommend a specific weld-through primer product or part number.
