Friction stir welding: Double spindle FSW machine D-DSM

With the double-spindle FSW gantry systems in the D-DSM series, Grenzebach enables even faster and more efficient work. D-DSM stands for Double-Spindle Dynamic Stirring Machine. By adding an additional gantry bridge to the DSM, users have two independently operating welding heads at their disposal.

The second gantry bridge means that cycle times can be cut in half, resulting in economical production at high volumes. The two welding heads work independently of each other. This allows you to weld in parallel at different points on a workpiece during friction stir welding, so large components can be processed efficiently. Space and equipment requirements in production are reduced, while efficiency is increased.
The overall investment is significantly lower. In addition, space is freed up for other applications.

Friction stir welding  

The friction stir welding technology (FSW) by Grenzebach enables the joining of technically pure metals, alloys and mixed material compounds while providing a solid bond of exceptional quality. During the FSW process a rotating, wear-resistant welding tool generates frictional heat at the welding zone. The material becomes malleable and is stirred along the welding path by the welding tool without reaching the melting temperature of the joining materials. The stirred material is compacted by the tool shoulder and a solid, media and pressure-tight joint between the work pieces is formed. Compared to conventional fusion welding processes (e.g. arc welding), FSW does not require additional welding wire, inert gas or complex exhaust systems. Furthermore, FSW does not generate any discernible noise, emissions or optical radiation.
