Weld Bonding Required on Chrysler Vehicles
So you've got a Chrysler sitting in your repair facility and a service part, but no installation procedure. What do you do? On any other steel vehicle, you would duplicate the original attachment method and plug welds are ok, but not a Chrysler. A couple of years ago (August 14, 2013 to be exact) Chrysler released the collision repair bulletin, Welded Sheet Metal Repairs and Replacements 31-007-12, that changed the way that their vehicles should be repaired. In this bulletin it states that: "weld bonding of replacement panels is the recommended installation method to utilize when repairing Chrysler, Dodge, Fiat, Jeep, or Ram vehicles."
In addition: "GAS METAL ARC WELDING (GMAW or MIG) SHOULD ONLY BE USED IN THE FOLLOWING SPECIAL CIRCUMSTANCES:
- Proper weld access cannot be attained utilizing STRSW equipment with any of the available accessory arms.
- Utilize 6-8 mm ring fillet welds for exterior panels and 8-10 mm for all others.
- Adhesives need to be kept 25 mm from a ring fillet weld due to their flammability.
- A Chrysler publication explicitly calls out fusion welding as the proper repair method.
- The original attachment was GMAW."
