Regardless of the cause of vehicular damage, the repairers moral obligation is to repair the vehicle to the original design intent relative to
safety, NVH, comfort, durability, and corrosion protection by duplicating the original construction as closely as possible by
following all manufacturers guidelines. With the increasing use of advanced high strength steels in body construction, and their
susceptibility to degraded material properties from welding heat, the approved process for installation of replacement panels has
changed.
Chrysler has previously approved the use of "weld bonding", where squeeze type resistance spot welding (STRSW) is combined with an
approved structural adhesive, as one of the acceptable methods to install welded panels while maintaining the original appearance and
corrosion protection.
High quality and capable STRSW equipment, which was a rare shop tool in the collision repair industry, has now become the norm and
with this, it is now important to state that weld bonding of replacement panels is the recommended installation method to utilize when
repairing Chrysler, Dodge, Fiat, Jeep, or Ram vehicles.
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 68 mm ring fillet welds for exterior panels and 810 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.
ALL OF THE FOLLOWING GUIDELINES MUST BE ADHERED TO:
^ DO NOT use heat to straighten sheet metal unless the panel will be replaced.
^
If weldon pulling studs are used, their use must be minimal and the backside of the repaired panel must also be repaired to restore
the original corrosion protection.
CHARACTERISTIC OF ACCEPTABLE STRSW EQUIPMENT:
^
^
^
^
^
Must utilize 220 volt (or greater), threephase power supply.
Must utilize inverter technology
Must have the capability to provide a minimum of 10,000 amps of output.
Must have the capability to provide 600 pounds of tip force (267 daN) with the longest arms
Should utilize "smart" technology which helps eliminate errors in equipment setup.

ONLY Lord Fusor # 112B or 3M # 08116 have been approved by Chrysler for weld bonding. These materials provide corrosion
protection in the vulnerable weld zone. Joint sealers should be applied after welding is complete and appropriate primers have been
applied (if needed).
Only remove ecoat from the new panel at the weldbond mating location.
Minimize removal of galvanize/galvanneal coating.
Solvent wipe with suitable product before application of adhesive.
Initial application of adhesive should be spread from the bare metal onto the ecoat to provide a continuous corrosion barrier.

Never use "weldthru" primer.
Completing all welded panel replacements requires applying a coating of creeping rust inhibitive material in all areas where any welds
were made, even where weldbonded.
Replacement panels must be installed as provided, and utilizing the methods described in this bulletin, unless additional guidelines
are made in another Chrysler Collision Repair Bulletin, Chrysler Body Repair Manual, or other Chrysler approved publication.
Failure to follow these repair guidelines will result in a vehicle which may not duplicate the original design intent in terms of function,
safety, and durability.

SUBJECT:
Do Not Apply Corrosion Protection On SMC (Plastic) Panels
OVERVIEW:
This bulletin involves discussing SMC (plastic) panels and applying corrosion protection.
DISCUSSION:
The application of corrosion protection on SMC (plastic) panels is unnecessary and not recommended. It can adversely affect the paint or
any other coating applied to the substrate. In some instances it can cause a condition commonly referred to as solvent popping shown in
(Fig. 1). Although the condition appears to be repairable, it will reoccur because the SMC substrate is porous and has essentially
absorbed the corrosion inhibitor, which will cause the condition to reoccur. Panel replacement is required when solvent popping is evident
on SMC (plastic) panels when corrosion protection materials have been applied.2010 Jeep Truck Grand Cherokee 4WD V63.7L

DISCUSSION:
Models equipped with Chrome Clad wheels require specific piloting on balance equipment to properly center the wheel and prevent
damage to the chrome clad surface. The chrome cladding is not removable or replaceable and has cladding tabs that extend into the
wheel bore. Traditional hightaper cones will come into contact with the cladding tabs rather than properly seat on the hub bore chamfer.
Many modern aluminum wheel designs cannot be mounted with traditional cones. DirectFit Collets should be used to properly mount
clad wheels on balance equipment (Fig 1).

DISCUSSION:
Models equipped with Chrome Clad wheels require specific piloting on balance equipment to properly center the wheel and prevent
damage to the chrome clad surface. The chrome cladding is not removable or replaceable and has cladding tabs that extend into the
wheel bore. Traditional hightaper cones will come into contact with the cladding tabs rather than properly seat on the hub bore chamfer.
Many modern aluminum wheel designs cannot be mounted with traditional cones. DirectFit Collets should be used to properly mount
clad wheels on balance equipment (Fig 1).
