Weld-Through Primer Guidelines: Tesla - UPDATE

Weld-Through Primer Guidelines: Tesla - UPDATE

Weld-through primers are generally a zinc-based product that is 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 MIG 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 Tesla recommends and where this information can be found.

Weld-though primer recommendations can be found in vehicle-specific body repair manuals under: Collision Repair Procedures ➤ Approved Parts, Tools, and Supplies ➤ Approved Welders.

Within this area, there is a caution statement that identifies when to use weld-through primer. This caution statement is located at the bottom of Approved Welders. Tesla doesn’t call out a specific product but states to use a suitable zinc weld-though 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.
