Weld-Through Primer Guidelines: Fiat Chrysler Automobiles - UPDATE

Weld-Through Primer Guidelines: Fiat Chrysler Automobiles - UPDATE

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 Fiat Chrysler Automobiles (FCA) recommends and where this information can be found.

FCA has recently updated their weld-through primer recommendations. Previously written manuals by Fiat recommended the use of weld-through primer, while Chrysler written manuals advised against the use of weld-through primer. The newly updated editions of all FCA manuals forbid the use of weld-through primer. However, you may find that currently on the free site that some manuals have not yet been updated and still recommend using weld-through primer. Per our contact at FCA, the free site is still in the process of being updated and weld-through primer should not be 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.
