Weld-Through Primer Guidelines: Volkswagen
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 Volkswagen recommends and where this information can be found.
This information, along with other part preparation guidelines, can be found in the vehicle-specific General Information Body Repair, Body Collision Repair Manual. Volkswagen states:
- “welding primer must always be applied to both sides of welded flanges.
- always apply welding primer between joint flanges.
- to use part number D 007 500 04 for weld-through primer.
- DO NOT use zinc spray when in areas where adhesives are being used.”
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.
For additional Volkswagen information, check out the Volkswagen OEM Information page.
