  1. General information 
    • For repair cases the following procedure will implemented:
      • Brazing solder
    • The MIG soldering procedure is not used in repairs for strength reasons. MIG soldered/brazed seams used in standard production are replaced during repairs by MAG weld seams. 
    • Brazed areas from vehicle production are bonded following the same procedure.
  2. Work materials 
    • Tube pack and torch
    • Brazing solder
    • Gas bottles (oxygen and acetylene)
    • Welding goggles
  3. Preparation 
    • Remove the paint and zinc layer in an area of approx. 30 mm around the seam to be soldered.
  4. Implementation 
    • Execute brazed seam without overheating the solder and with low heat dissipation. If necessary, use heat protecting paste.
  5. Subsequent treatment of brazed connections: 
    • Remove burnt residual zinc completely. Align and grind visible connection faces.
    • Remove burnt paint with a stainless steel wire brush.
  6. Notes on melting/tinning: 

    Only applicable within the European Union!

    European used-vehicle regulations prohibit the use of tin containing lead in motor vehicles introduced after 01.07.2003!
