501-25-69 Body Repairs - General Information 501-25-69 DESCRIPTION AND OPERATION ‡ They are air and watertight. ‡ High corrosion protection ‡ Different materials can be connected. ‡ Bonding can be combined with resistance spot welding. NOTE: The quality of the bonded connection is largely dependent on the care taken during preparatory work. When gluing bodywork parts, follow the work instructions from the adhesive manufacturer. Bonding and welding On some vehicle models, (such as the Ford Ka), bonding is combined with resistance spot welding. This connection technique has the following advantages: ‡ Tight, anti-corrosion connection seam. ‡ High strength due to additional resistance weld spots. Please note the following points during the repair work: ‡ Only use adhesive suitable for welding (conductive). ‡ Carry out resistance spot welding on the connection flanges before the adhesive hardening process. ‡ Carry out test welding with the adhesive applied. ‡ If MIG welding is carried out during a sectional repair on a connecting flange with sealant or adhesive material, the material must be applied at a distance of approx. 10 mm from the weld spot. ‡ These areas must be sealed very carefully after the work has been completed. Bonding and riveting As with welding, bonding can also be combined with riveting. This connection technique has additional advantages. These are: ‡ Metallic and non-metallic materials can be joined together. ‡ Different thicknesses of materials can be used. ‡ The material does not have to be heated, and therefore does not warp. ‡ The rivet connection stabilizes the connected components during the adhesive hardening phase.
