Ideal aluminum welding

Aluminum alloys, whether from cast or wrought material, welded media-tight and with minimal distortion – even mixed compositions can be produced reliably with the Grenzebach Friction Stir Welding technology (FSW). 

From battery tray to heat exchanger

In addition to excellent mechanical properties, the joints are also characterized by their high dimensional accuracy. The DynaSTIR technology developed by Grenzebach allows for producing outstanding surface qualities. Grenzebach offers a broad portfolio of FSW machines that can be tailored to customer and project specific production solutions.

During Friction Stir Welding, a rotating tool generates the required process heat via friction and pressure at the process zone. The heated material turns malleable and is stirred along the seam by the rotation of the tool. As a result, media-tight and durable welding joints are being produced that show very little structural deformations or residual stresses, ideal for welding of e-mobility battery trays, heat exchangers or structural components. Turnkey FSW production plants from Grenzebach convince due to a high degree of automation and a dynamic process control leading to extraordinary robustness of the welding process.

The international trade show in Nuremberg focuses on optimized processing of high-pressure die-cast parts with the Friction Stir Welding technology.

Friction Stir Welding

During the solid-phase joining process, the temperature stays below the melting point of the material.

  • Joining of aluminum alloys that are known not to be fusion-weldable or hard to do so

  • Particularly suitable for joining mixed compositions with different alloys and metals as well as different product forms, such as wrought alloys with aluminum die cast

  • No hot cracking or formation of hydrogen pores

  • Highly reproducible seam strength and quality

  • No auxiliaries, such as inert gas, powder, welding wire etc. required

  • No workplace pollution through dust, gases, smoke or radiation

Application industries:

  • Automotive
  • Energy transmission / Power electronics
  • Battery production
  • Rail vehicle manufacturing
  • Aerospace technology
  • Consumer electronics
