41 00... Soldering steel components

IMPORTANT: Conform with SAFETY INFORMATION
Handling electrical system, electronics, airbags and restraint systems. See HANDLING AIRBAGS AND RESTRAINT SYSTEMS or HANDLING ELECTRICAL SYSTEM AND ELECTRONICS .

General information:
- For repair cases the following procedure will implemented:
  - Autogenous 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.
Work materials:
- Tube pack and torch (autogenous torch)
- Brazing solder
- Gas bottles (oxygen and acetylene)
- Welding goggles
Preparation:
- Remove the paint and zinc layer in an area of approx. 30 mm around the seam to be soldered.
Implementation:
- Execute brazed seam without overheating the solder and with low heat dissipation. If necessary, use heat protecting paste.
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.
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.

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.
