Automobile suppliers today rely on forming and joining in the production of steering columns. Compared with cast parts, which have long been installed in steering columns, the combination of the two methods offers clear advantages. Forming and joining, in particular by laser welding, help to meet the high standards and standards of the automotive industry in terms of safety and profitability.
Forming processes allow a resource-efficient and cost-effective stage sequence. Steel or stainless steel sheets are (partly) automatically punched and assembled into laser-welded sheet metal assemblies. The entire value-added chain from sheet metal to the finished steering column thus remains within the company.
When choosing the joining process, production managers are increasingly choosing laser welding systems. Compared to MIG welding and MAG welding, laser welding offers the following advantages for the steering column:
- Butt welds of high quality
- 3 to 5 times higher production speed
- Simple, fast and cheap production
- Material and cost savings
- Less spatter
Joining methods such as gluing and soldering are not an option for steering columns as they fail in the high temperature range. At high temperatures, for example in the exhaust system, the compounds dissolve.
