Soldering steel components
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2019 MINI Cooper, 2018 MINI Cooper, 2017 MINI Cooper, 2016 MINI Cooper, and 2015 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
Comply with all applicable SAFETY INFORMATION .
Observe notes on handling ELECTRICAL SYSTEM/ELECTRONICS and AIRBAGS/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.
- For repair cases the following procedure will implemented:
- Work materials
- Cable hose assembly and flashlight (oxyacetylene blowtorch)
- 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 areas.
- 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 cars 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.
