Numerical Simulation of Temperature Field of Linear Friction Welding of 45# Carbon Steel

Abstract:

A 3D finite-elements model of 45# carbon steel of linear friction welding is built with the dynamic explicit code ABAQUS/explicit. The temperature field of workpiece, and the temperature change of center point of welding interface are showed in results. The center temperature of welding interface soars to 800°C, but the temperature of both ends of the welding interface are only 400°C or so at 0.75s. Then, the interface temperature rises slowly to about 920°C and maintains until welding ends.
