501-25-63 Body Repairs - General Information 501-25-63 DESCRIPTION AND OPERATION in whilst maintaining a required welding gap (welding gap same as panel thickness). NOTE: The butt joint requires a high degree of accuracy and care when trimming and cutting. For correct execution of the welding, an exact, even welding gap must be maintained. Preparation of the joint areas includes: ‡ Sanding the connection areas bare on both sides. ‡ Removal of the zinc layer in the welding area. ‡ Carrying out welding tests on an equivalent sample panel before the actual welding, if necessary. ‡ Tack welding in the join area: From the edges to the centre, then check the shape. ‡ Joining new and old parts with a full seam weld. Joggled joint 1 2 3 E54129 Des Description FULSW ion 1 Body part 2 Joggled area 3 New panel The joggled joint variant is restricted to body areas with a good surface condition without beads/swage lines or profiles. A sectional replacement with a joggled joint is welded using a continuous seam. This procedure is used, for example, at the transition from the side panel to the rocker panel (3-door vehicles). When cutting the new part, slight measuring tolerances are permitted, as these are covered by the joggled area. Preparation of the joint areas includes: ‡ Sanding the connection areas bare on both sides. ‡ Removal of the zinc layer in the welding area. ‡ Preparation of a joggled strip. ‡ Carrying out welding tests on an equivalent sample panel before the actual welding, if necessary. ‡ Joining the new and old panel with continuous seam welding. ‡ Lead loading the weld seam.
