1. General information
- For repair cases the following method will implemented:
- Gas brazing
- The MIG soldering procedure is not used in repairs for strength reasons. MIG soldered/brazed seams used in series production are replaced in repairs by MAG weld seams .
- Brazed areas from vehicle production are bonded with the same method.
2. Work materials
- Tube pack and torch (gas torch)
- Brazing solder
- Gas bottles (oxygen and acetylene)
- Welding goggles
3. Preparation
- Remove the paint and zinc coating 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 joints:
- 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-car regulations prohibit the use of tin containing lead in motor vehicles introduced after 01.07.2003!
Even out unevenness smaller than 2 mm with filler according to painting handbook
If an exceptional unevenness is larger than 2 mm, use METAL FILLER .
Only perform in visible areas of the outer skin and on the carrier support.
All areas which have covers on the vehicle are not to be processed.
