The intense international competition in the automotive sector has always been strongly innovation-driven. It requires a continuous process of re-evaluating and improving its own products and supply chains. In addition to the innovation aspect, all OEMs and suppliers are subject to particular requirements in the area of quality assurance, reproducibility, and traceability.
The endless possibilities of vacuum brazing, vacuum heat treatment, and diffusion bonding as batch processes have yet to gain widespread acceptance compared to continuous processes, but offer enormous potential, above all with regard to geometric freedom of joint accessibility, the high strength and corrosion-resistance of the manufactured parts, and the ability to manufacture hybrid joints. What’s more, rework expenditure is virtually eliminated, not least to the benefit of high levels of manufacturing efficiency.
Especially in the promising market of electromobility, the technologies of vacuum brazing and diffusion bonding offer solutions for challenging joining problems and the realisation of complex geometries.
One potential is the optimal connection of copper components, a core element of the power supply in electric vehicles. Two-dimensional joints can be realised both by vacuum brazing and diffusion bonding. But also for other materials, such as steel or aluminium, which are required in the context of electromobility, the technologies of vacuum brazing and diffusion bonding provide reliable solutions for otherwise problematic joining tasks.
- High strength
- Low-defect joints for excellent electrical and thermal conduction properties
- Excellent corrosion resistance
