- Friction Stir Welding Technology
Whether casting or wrought alloys or even mixed combounds, with Grenzebachs’s Friction Stir Welding (FSW) technology weld seams with excellent properties can be produced.
In addition to excellent mechanical properties, the joints are also characterized by their high dimensional accuracy.
The DynaSTIR technology developed by Grenzebach also allows outstanding surface qualities to be realized. Suitable for this, Grenzebach offers a broad portfolio of FSW machines that can be customized to customer-specific 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 heatened material becomes malleable and is stirred along the seam by the rotation of the tool. In this way, media-tight and durable welding joints are created, which are accompanied by low structural deformations or residual stresses. Ideal for welding of battery trays, heat exchangers or structural components for the e-mobility. Turnkey FSW production plants from Grenzebach convince by a high degree of automation and a dynamic process control, which lead to an extraordinary robustness of the welding process.
Nuremburg, Linz, Nashville: Grenzebach present the new Friction Stir Welding systems of the D-DSM series at three exhibitions.
A plus in aluminum processing. During the Aluminum fair at Düsseldorf Grenzebach will show how the DynaSTIR technology, a further development in the friction stir welding (FSW) sector, allows the users to increase their value added chain.
Aichi Sangyo introduces the FSW technology from Grenzebach in Japan
The process temperature in the solid phase joining technology is below the melting point of the materials.
Joining of aluminium alloys that are not or hardly fusion-weldable
Particularly suitable for the joining of mixed compounds with different alloys and metals as well as different product forms (e.g. wrought alloys with aluminium die cast)
No formation of hydrogen pores or hot cracking
Highly reproducible seam strength and seam quality
No auxiliaries, such as inert gas, powder, welding wire etc. required
No significant impact on the work environment due to dust, gases, smoke, radiation etc.
