With the friction stir welding technology from BOCK you rely on high quality, durable and innovative components.

BOCK - Your competent partner for friction stir welding

Joining without melting the joining partners - this is now possible thanks to the new technology of friction stir welding (FSW). In this process, the materials are stirred instead of melted, resulting in a pressure-tight and extremely durable weld seam.

At BOCK, we provide you with competent support throughout the entire process - from your inquiry to the finished series product. We convince with many years of experience in the production of industrial components for the automotive industry and an all-round service at all times. As a family-run company, development, conception and implementation take place from a single source, which enables us to implement every inquiry promptly and to always comprehensively control the quality of our industrial components.

What is friction stir welding?

Friction stir welding is a low-heat joining process in which the materials are stirred and - in contrast to conventional arc and laser beam welding - not melted. The required heat input is generated by friction between the friction stir welding tool and the materials to be joined. The material heats up and becomes plastically deformable. Friction stir welding is thus particularly suitable for joining non-ferrous metals and alloys with low melting temperatures, as well as mixed metallic joints.

The automotive industry, or more precisely the area of e-mobility, represents a large area of application. We at BOCK manufacture DC/DC converters for this industry using friction stir welding and thus support our customers on their way to more sustainable mobility. With our friction stir welding technology, we can weld components for the future that are lightweight yet robust and of the highest quality.

Quality that convinces

  • Durable, particularly tight weld Low-warpage joints
  • No pores or hot cracks in the material due to comparatively low heat input
  • Long-lasting joint structure

High cost-effectiveness: resource-saving

  • Low-energy joining process
  • No need for weld preparation and postprocessing
  • Savings on filler materials such as welding wire, shielding gas, adhesives and screws
  • Autonomous production possible
  • In line with Industry 4.0
