Abstract

The Orbital friction welding process utilizes high heat generated at the interface from friction to form a high strength weld. A full transient thermal 3D analysis combined with axial displacement was conducted using ANSYS to simulate this welding process. The goal was to model the process of orbital friction welding by incorporating industry-relevant parameters under realistic boundary conditions. The work illustrates the dependency of the temperature profile on various processing parameters at any point in time in the welding process. The mathematical results are compared and analyzed with measured experimental data. The numerical model is used to predict the temperature flow in orbital friction welding under typical process conditions.
