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.

Grenzebach is a leading automatization solution provider for the global glass, building material and intralogistics market. In addition, the company develops new application areas, such as friction stir welding, the automatization of industrial additive manufacturing and digital networking. The digitalization platform SERICY allows customers to develop their own future-proof digital know-how. Grenzebach ranks among the international technology leaders in its markets. The global manufacturing footprint with production sites in Germany, Romania, the US and China, as well as additional worldwide locations ensure customer support on-site. More than 3,000 systems installed in more than 55 countries stand for quality and reliability. Since the company opened its doors 60 years ago, it has been owned by the founding family. With an export ratio of more than 90 percent, Grenzebach is a global player.

Friction stir welding (FSW) is the innovative welding process for joining materials durably and robustly. The metals are stirred, not melted. FSW can be optimally integrated into industrial series production. Grenzebach is your automation partner from the very beginning. Different equipment concepts are available – from gantry machines with customer-specific working ranges to robots, which weld 3D geometries. Developing processes and providing friction tools are part of Grenzebach’s holistic approach.

Grenzebach manufactures high-quality castings for industrial use. Grenzebach designs and builds molds and models exactly according to customer requirements and thus provides the individual foundation for an optimized series production. In the machining center at the Chinese site in Jiashan, the castings are processed in accordance with European and international quality requirements. Grenzebach takes care of the entire supply chain: from consulting, design, and prototype development to casting and machining as well as quality control and logistics.
