Radial Friction Welding

The bonds of T2 copper/50steel were studied by inertial radial friction welding techniques at different conditions. Ultrasonic C-scan testing was employed to evaluate the bonding situation. In order to verify the reliability of ultrasonic C-scan testing results, the optical microscope, SEM and shear test were used to analyse the microstructure and mechanical properties. It was found that ultrasonic C-scan testing was useful to evaluate the inertial radial friction welding joint situations by analyzing the ratio of good bonded area in the bond area of ultrasonic C-scan images. And the correctness of ultrasonic C-scan testing was testified by microstructure examination. Furthermore, it was concluded that enough metalline plastic deformation occurred, oxide film of joint was destroyed and constituent elements were mutually diffused sufficiently, when two stage pressure was employed and friction pressure 78 MPa, friction speed 3200r/min were used.

Radial Friction Welding

The joint property of aldary (T3 copper, B5 cupronickel and H96 brassiness) with 35CrMnSi by the use of inertial radial friction welding techniques is studied to meet the requirements of product operation . The microstructure of the welding joint, shear testing, vickers hardness and electron probe tests are carried out to verify the material weldability. The results show good performance of T3 copper, B5 cupronickel and H96 brassiness welded well with steel. The joints shear strength is more than 200Mpa, and no air hole flaw in weld seam that often occur in general fusion welding with dissimilar material. The welding properties can satisfy the requirements of the products. The results also indicate that under the same welding specification, the region of HAZ is related to thermal conductivity and melting point of copper-alloy, the microstructures of HAZ on B5＋35CrMnSi steel side is wider than others .
