Body Panel System - Full Frame and Body Mounting: Other Ford Econoline E350 Super Duty

Welding Precautions

1. If welding must be done on a frame, make sure the following requirements are met: If the frame is attached to the vehicle, the battery ground cable must be disconnected before using any electrical welding equipment. Refer to «BATTERY, MOUNTING AND CABLES»(ref-231356) for correct battery disconnect procedures. Do not use gas welding equipment. Arc welding is the only approved method. Use a temperature-indicating crayon to make sure that the temperature does not exceed 750°C (1400°F). Replace spot-welded components by spot welding where possible. If spot welding is not possible, use puddle welding.

Frame Straightening

1. When straightening the frame, make sure the following requirements are met: If heat is needed to straighten a frame member, keep the temperature below 650°C (1200°F) (a dull red glow). Heat must be kept to a minimum area so that the hardness of the metal will not be affected. Straightening must only be attempted on frames that fail to meet specifications of the diagonal checking method or where damage is apparent. Straightening must be limited to parts which are not severely bent.

Scheme 6

1. After a bent frame member has been straightened, inspect the frame member closely for cracks. If any cracks are located, the damage must be welded and, if necessary, reinforced.
2. The following procedure details the recommended frame crack repair procedure: Stop drill the crack(s) at the end. V-grind the crack(s) in preparation for welding. Weld the crack(s). Grind off the weld excess. Add a reinforcing plate if necessary. The reinforcing plate must be made from flat or angle stock of the same material and thickness as the frame member being reinforced, and must extend to either side of the crack. Ideally, the reinforcement will be cut from the corresponding area of a similar frame. Weld the reinforcing plate entirely, using the skip weld method to reduce potential heat buildup from concentrating in any one particular area during repair.
