Automotive: Production of sheet metal assemblies for the automotive industry

 

 

 

 

 

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.

Requirements of the automotive industry on steering columns

 

  • Low weight
  • Dynamic rigidity
  • Simple, fast and cheap production
  • High product quality
  • Low material costs

Production of steering columns by forming and joining: the advantages

In order to illustrate the advantages of forming and joining in the production of steering columns, the comparison with castings is worthwhile.

Weight Loss

Steering columns made of sheet metal assemblies are comparatively light and thus contribute to the goal of the automotive industry to reduce the weight of components and the car. Castings, on the other hand, have a high dead weight.

Editing and effort

The modular solutions from weil technology reduce the workload. Casting is more time-consuming and usually requires mechanical post-processing (eg trimming, burrs, etc.). In addition, the manufacturing process for employees is intense and uncomfortable.

Dynamic rigidity

The components of the steering column should deform on impact to absorb energy. Sheet metal assemblies made by forming and joining have this capability. This is not true for castings.

Procurement and logistics

The main supplier for casting is China. The material lays down a long and therefore expensive journey until processing, which is associated with a higher risk of failure. A threat to the delicate balance of the supply chain.

Process optimization

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.

Components quality

As a joining process, welding - and especially laser welding - is much cleaner than casting parts. The higher precession thus ensures a better quality of the components of the steering column.

Add components of the steering column by laser welding

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.
