This article explains the use of the response surface method to produce the optimum tensile strength for the joining of dissimilar metals with the continuous drive friction welding method. The joining of dissimilar metals is one of the biggest challenges in providing industrial applications. Continuous drive friction welding has been extensively used as one of the important solid-state welding processes. In this study, the optimization of the friction welding process parameters is established to achieve the maximum tensile strength in AA6061 and AISI304 dissimilar joints via the response surface methodology. The effect of continuous drive friction welding parameters, which are friction pressure, friction time, upset pressure, and upset time, are investigated using response surface analysis. The design matrix factors are set as 27 experiments based on Box-Behnken. The 3D surface and the contour is plotted for this model to accomplish the tensile strength optimization. The optimization model of the tensile strength was verified by conducting experiments on the optimum values of the parameters based on the experimental data results. It can be denoted that the optimum process parameters settings were friction pressure = 25 MPa, friction time = 6 seconds, upset pressure = 140 MPa, and upset time = 8 seconds, which would result in a maximum tensile strength of 228.57 MPa.

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 .
