2021-2022 Stellantis Weld Through Primer Procedures

FCA US LLC, the manufacturer for Stellantis brands, has released a technical bulletin (NHTSA ID 10225424) clarifying the approved procedures for using weld through primers. This bulletin is crucial for ensuring proper body repairs on various 2021-2022 Stellantis vehicles, including the Alfa Romeo Stelvio, Jeep Grand Wagoneer, Dodge Challenger, and RAM 1500, among others. The guidance specifically addresses the application of these primers during Squeeze Type Resistance Spot Welding (STRSW) and Gas Metal Arc Welding (GMAW) processes on steel body panels and structural components.

Understanding Weld Through Primers

Weld through primers are specialized coatings applied to metal surfaces before welding. Their primary purpose is to provide corrosion protection to areas that would otherwise be difficult to access and coat after the welding process is complete. These primers are designed to allow electrical current and heat to pass through them effectively, ensuring a strong and reliable weld without compromising the structural integrity or corrosion resistance of the repaired area.

Approved Welding Processes

The bulletin (NHTSA ID 10225424) focuses on two key welding techniques: Squeeze Type Resistance Spot Welding (STRSW) and Gas Metal Arc Welding (GMAW). STRSW is commonly used for joining sheet metal panels, replicating the factory spot welds. GMAW, also known as MIG welding, is versatile and used for various repairs, including those on structural components. The proper use of weld through primers with these methods is essential for maintaining the vehicle's original design specifications.

Importance for Body Repairs

For vehicles like the 2022 Alfa Romeo Stelvio, maintaining structural integrity after a collision or repair is paramount for occupant safety and vehicle longevity. This technical bulletin ensures that repair facilities adhere to manufacturer-specified guidelines when repairing steel body panels and structural components. Following these procedures helps prevent future corrosion in critical areas and ensures the vehicle's crashworthiness is not compromised.

What This Means for Owners

As an owner of a 2021-2022 Stellantis vehicle, it's important to be aware of these manufacturer guidelines, especially if your vehicle requires body work. When your vehicle undergoes repairs involving welding on steel body panels or structural components, ensure the repair facility employs certified technicians who follow the latest manufacturer communications, such as this TSB. This diligence helps guarantee that your vehicle, including the Alfa Romeo Stelvio, is repaired to the highest standards, preserving its safety features and corrosion protection.

For Repair Professionals

This bulletin serves as a vital reference for collision repair centers and technicians working on 2021-2022 Stellantis vehicles. It provides clear guidance on the FCA US LLC position regarding weld through primer application, ensuring that repairs meet the manufacturer's stringent quality and safety standards. Adhering to these procedures is crucial for delivering high-quality, durable repairs.
