Friction stir welding

Friction stir weldingNew technology that proves itself

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.

ADVANTAGES OF THE NEW TECHNOLOGY

  • Durable, particularly tight weld seam
  • No pores or hot cracks due to low heat application
  • Durable, low-warpage connection design
  • Low-energy and emission-free joining process
  • Seam preparation and postprocessing not applicable

  • Savings on welding wire, shielding gas, adhesive and screws

  • Autonomous manufacturing possible

  • In line with Industry 4.0

  • No auxiliary materials such as shielding gas or welding wire required

  • No exposure to radiation, gases and smoke

  • Technology with a future – components for e-mobility

Friction stir welding enjoys great popularity, especially in the marine industry, the railroad industry and the aerospace industry. Even at the US Aeronautics and Space Administration NASA, the technology is used with great success for rockets, spacecraft or external tanks.

Another large area of application is the automotive industry, more specifically the field of e-mobility. 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.
