FCA/Stellantis: Who Requires Or Recommends MIG Brazing?

In Europe, MIG brazing has been required or recommended on a widespread basis for several years. In the U.S., MIG brazing is not as common but is becoming more prevalent. As the RTS team is researching MIG brazing information, we are putting together a series of articles that identify OEM-specific MIG brazing recommendations and requirements for vehicles in the U.S. Let’s see what FCA/Stellantis has to say.

MIG brazing information is typically located in the Welding and Weld bonding and Sectioning Locations and Component areas of vehicle-specific body repair manuals (BRMs). The information in these documents may differ slightly depending on the specific vehicle.

When searching the BRM, you may notice a general statement for very high-strength steel that says, "May be attached using STRSW, weld bonding and Metal Active Gas (MAG) brazing to minimize heat affected zone." MIG brazing locations are specified within repair procedures of vehicle-specific body repair manuals and should be followed.

Some of the MIG brazing information you will find in these documents includes:

• MIG brazing wire specification
• Material thickness range
• Shielding gas requirement
• Wire speed

FCA/Stellantis sates the following about MIG brazing:

• "Welding using brazing applies only if it is necessary to replace sheet metal that was previously welded with this type of welding and should only be carried out at the points recommended by the manufacturer.
• This type of welding does not guarantee mechanical properties that are comparable with the other systems described previously and therefore does not apply to the joining of structural components.
• It has a reduced heat affected zone as compared to GMAW.
• The lower heat involved will not affect the strength properties of the metal being welded
• MIG braze welding process requires use of Pulse Arc or STT welding machine."

It is important to note that MIG brazing should only be used where indicated in a vehicle-specific repair manual or where specified by the OEM to help ensure a complete, safe, and quality repair.
