501-25-61 Body Repairs - General Information 501-25-61 DESCRIPTION AND OPERATION Special features to note when puddle welding: ‡ The panels to be joined must lie perfectly flat to one another. ‡ The panel flanges must be treated with corrosion protection. The position of the weld must be bare. ‡ Prepare the holes depending on the thickness and number of the panels. The hole size should be 6-10 mm, or match the original weld spot. ‡ Start the welding procedure on the panel at the bottom so that the hole is filled completely. Continuous bead welding A welded joint with a full seam is suitable for joining highly profiled body parts. Pillar and sill areas are typical application areas. E115419 Special features to note during bead welding: ‡ Both parts of the panel must be bare on both sides over a width of 5 mm. ‡ Align the parts precisely with clamps. ‡ To prevent the panel from warping, tack longer joints before welding them. Intermittent bead welding Intermittent bead welding is used when the connecting flanges are stepped. This form of seam is mainly used on the external panel area for sectional repairs.
