41 00... Soldering Steel Components

IMPORTANT: Comply with the following topics from "BODY, GENERAL ":
Safety regulations. See 41 00... SAFETY AT WORK , 41 00... HANDLING ELECTRICAL SYSTEM AND ELECTRONICS and 41 00... HANDLING AIRBAGS AND RESTRAINT SYSTEMS .

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. See 41 00... OVERVIEW OF CONSUMABLES (1.3 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.
