Article Preview

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 .
