Electric simulation inertia friction welding technology

In order to adapt to the current development of friction welding equipment and reduce the manufacturing cost, the electro-simulated inertia friction welding technology and equipment are developed, based on the analysis of the kinematics equation of inertia friction welding process and the electric simulation inertia technology. The result shows that the regularity of the change of parameters over time and the influence of inertia size on welding parameters are in accordance with the general law of inertia friction welding during the electric simulation. The rotational speed curve of inertial friction welding is consistent with that of mechanical inertia friction welding process under the same inertia. The inertia can be set to be larger than the basic inertia of the system, and can be set to equal or lower than the basic inertia of the system by electric simulation inertial friction welding technology. The effect of friction resistance of spindle on the parameters of welding process can be compensated by electro-simulated inertial friction welding technique.
