The friction welding process belongs to the group of pressure welding processes. The friction welding process is divided according to the type of relative movement and the type of energy used. Typical processes are friction stir welding, orbital friction welding, rotary friction welding. During the welding process, the components to be welded move relative to each other. The parts to be joined are brought together at the contact surfaces and heated by translational and rotational movements. Once the process temperature has been reached, the parts are plastically deformed under great force. The rotation stops, and the force applied is increased and maintained so that the parts to be joined form a material bond.
The special feature of this process is the flexibility to combine a wide variety of materials. The technology of friction welding is known for a secure and economical connection of different materials.
Friction welding system and annealing system at Zipp Industries
Zipp Industries GmbH & Co. KG uses the process of rotary friction welding with continuous drive. We weld our manufactured threaded connectors with the base bodies of our rotary augers or rotary drilling pipes. With our friction welding machine, we can weld different lengths, diameters, wall thicknesses and materials together. The cooling after the friction welding process takes place very quickly, causing stresses in the weld metal and the heat-affected zone. In order to eliminate these stresses, our welded products are stress-relieved in an annealing process.
We heat the pipe specifically at the weld seam and ensure that the stresses that have arisen are reduced. The diffusion processes are completed in the holding process. After the diffusion processes are completed, the product is specifically cooled. After completion of the annealing process, the welded joint is stress relieved.
In addition, we offer you friction welding for your individual welded joints in contract work. Our own friction welding system allows us a high degree of flexibility when confirming delivery dates.
