501-25-65 Body Repairs - General Information 501-25-65 DESCRIPTION AND OPERATION ‡ No corrosion of the brazed seam. ‡ Low erosion of the zinc coating in the joining area. ‡ Low level of heating and thus little warping. ‡ Easy finishing of the brazed seam. ‡ Good for bridging gaps. Technicians performing MIG brazing must use a Ford-certified MIG brazing device and must have been given appropriatetraining on the brazing techniques which are used. Only use the Ford-approved brazing solder SG-CuSi3 (SG-CuSi3Mn1). Unless specified otherwise, a minimum gap of 30 mm must be maintained between the MIG brazed seam and any adhesive bonds. 1 E135738 Des Description FULSW ion 1 Preparation of the MIG brazing: Flatten the old brazed seam with a grinder. CAUTION: MIG welds must not be carried out on or near existing MIG brazed seams as even the smallest amount of brazing solder can result in a reduction in the strength of the weld seam. If MIG brazing cannot be used then the factory-installed MIG brazed joints should be replaced with MIG welds in a different place during service repairs. These MIG welds must not be carried out on or in the immediate vicinity of existing MIG brazed seams as even the smallest amount of brazing solder can result in a reduction in the strength of the weld seam. Consequently, the corresponding graphics offer two alternative repair techniques (1: MIG brazing; 2: MIG welding). 2 Des Description FULSW ion 2 Preparation of the MIG welding: Grind the old brazed sean and the surrounding area until they are clean, and remove any residue of the brazed seam.
