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

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
