2023 Alfa Romeo Stelvio Weld Through Primer TSB

Understanding Weld Through Primers

Weld through primers are specialized coatings applied to metal surfaces before welding. Their primary purpose is to prevent corrosion in areas that become inaccessible after welding, while still allowing for a strong, clean weld. Proper application and approval of these primers are crucial for maintaining the structural integrity and corrosion resistance of a vehicle's body.

FCA US LLC Position on Welding Procedures

FCA US LLC has issued a Technical Service Bulletin (TSB) with NHTSA ID 10225287 to clarify its official stance on the use of weld through primers. This bulletin specifically addresses how these primers should be utilized when performing repairs involving steel body panels and structural components. The guidance provided ensures that repair facilities adhere to manufacturer standards, which is particularly important for vehicles like the Alfa Romeo Stelvio weld through primer applications.

Affected Welding Processes

The TSB details the approved use of weld through primer in conjunction with two specific welding methods:

• Squeeze Type Resistance Spot Welding (STRSW): This process uses heat generated by resistance to an electrical current to fuse metal sheets together at specific points.
• Gas Metal Arc Welding (GMAW): Also known as MIG welding, this process uses a continuous solid wire electrode fed through a welding gun, with a shielding gas protecting the weld from contamination.

Adherence to the specified procedures for both STRSW and GMAW is essential for ensuring the longevity and safety of repairs involving steel body panels and structural components.

Why This Information Matters

This manufacturer communication is vital for repair technicians and body shops working on FCA US LLC vehicles. It provides clear guidelines to ensure that repairs involving welding maintain the original factory specifications for corrosion protection and structural strength. For owners of vehicles such as the Alfa Romeo Stelvio weld through primer repairs, this means that any body repairs performed according to this TSB will meet the manufacturer's stringent quality and safety standards. Understanding the proper use of weld through primers helps prevent future corrosion issues and ensures the structural integrity of the vehicle.

What Owners Should Know

While this TSB is primarily for repair professionals, it assures owners that their vehicle's structural repairs are being conducted using approved materials and methods. If your vehicle requires body work involving welding, especially on steel body panels or structural components, you can inquire with the repair facility about their adherence to manufacturer communications like TSB NHTSA ID 10225287. This helps ensure your vehicle's long-term durability and safety.
