Weld-Through Primer Guidelines: Mazda

Weld-Through Primer Guidelines: Mazda

Weld-through primers are generally a zinc-based product that is applied to the mating surfaces prior to welding. When the weld is performed, the zinc liquefies and flows into the weld-pool, protecting the weld from corrosion. 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 in the General Information tab. Mazda:

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

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.
