Grenzebach friction stir welding technology allows the creation of welding seams with outstanding external and internal properties. The joints also distinguish themselves with a superior surface quality compared to traditional welding methods, in addition to excellent mechanical, electrical and chemical characteristics.
Innovative, Reliable, Turnkey
During friction stir welding (FSW) a spinning tool creates the necessary process heat by friction and pressure on the weld joint. The material becomes malleable due to the induced heat and is mixed by the rotation of the tool along the weld joint. In this way, durable and impermeable welding connections are created, which go hand in hand with low component deformations or residual stresses.
Turnkey FSW production plants by Grenzebach provide a high degree of automation and dynamic process control, which provides a consistent welding process. Our patented friction tools combined with the integration of all operation and control processes in a central control station are instrumental for the success of our plants.
With the introduction of robotic friction stir welding, Grenzebach has opened up completely new application opportunities in the field of FSW technology and already supports several applications in industrial 24/7 batch operations.
The active power control, in conjunction with the robot kinematics, not only enables full 3D capabilities of friction stir welding, but also allows joining in exigencies, such as in overhead or transverse positions. Even complex welding lines and parameters can be managed with our specialized programming (CAM) software.
To ensure excellent process stability, Grenzebach places great emphasis on higher level process and plant controls, so that the relevant parameters can be continuously monitored, adjusted, and recorded.
As a system integrator and provider of customized solutions with extensive experience, Grenzebach provides the complete process solution from layout, welding tools, fixtures and safety concepts to project management, testing, and process optimization. Training, production support, remote maintenance, and customer service round off our program and ensure long-term plant and process stability.
