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.
