Grenzebach Friction Stir Welding (FSW) with Gantry Systems DSM1400 & DSM2400

Seal welding for different industries and challenges: The compact 4-axis gantry machines of the DSM series (DSM = Dynamic Stirring Machine) was developed by Grenzebach especially for the requirements of the FSW process. The machine design is focused on a dynamic and precise process control as well as an intuitive control and operating concept.
Friction stir welding is low-emission and creates robust welding seams: A rotating tool generates the required process heat through friction and pressure at the welding seam. The heated material becomes malleable and is stirred by the rotation of the tool along the seam. The seam created is characterized by a special tightness. The result is a homogeneous structure with excellent properties. Because the sealing seam is also extremely resistant to mechanical stress, it can be used at structurally relevant points.
Compared to conventional fusion welding processes, such as arc welding, friction stir welding requires neither welding rod nor shielding gas or complex exhaust systems. Furthermore, the application is low-noise and does not generate any optical radiation.
