Direct Drive Friction Welding: A Comprehensive Mathematical Model

Abstract

This paper presents a theoretical study on direct drive rotary friction welding process and investigates the possibility of producing an analytical solution of the heat transfer equation, both during the first part of heating process and the second part of the process when the operative temperature of the material at the end of the rod is assumed to be constant and equal to plasticization temperature

Friction Welding Processes: A Review

“…The workpiece that is powered by the motor (figure 6) rotates at a set, steady speed. After forcing the work pieces that need to rotate for a predetermined time, a friction force is applied (Trancossi and Dumas, 2010). When the front surfaces of the materials known as weld interfaces rub against one another, heat is produced.…”

“…Fig. 6 Illustrative diagram of a direct drive friction welding (Senthil et al, 2020) After rotation stops, the friction force, also known as the forging force, is sustained or increased for a predefined duration (Trancossi et al, 2010). The usage of direct drive friction welding in production is growing due to its ability to create a strong bond between various materials and alloys, including heterogeneous components that are arduous to combine by means of conventional joining techniques (Titouche et al, 2019).…”
