Friction Welding Thermal Modeling of 15 CdV6 Alloy Steel

Friction welding has gained significant attention in recent years due to its efficiency and reliability, particularly in the context of solid-state metal joining techniques. This project focuses on the thermal modeling of rotary friction welding for 15CdV6 steel, a low-carbon alloy known for its high yield strength, toughness, and excellent weld ability. The primary objective is to simulate the temperature distribution within the weld zone under varying input parameters using ANSYS APDL software. Simulations were conducted for four different frictions and upsetting pressures: 30, 50, 70, and 90 MPa. The results provided insights into the maximum temperature attained during the welding process. Experimental validation was carried out and the results of peak temperature increase with higher friction pressures and it is consistent with the simulation results. The error between the simulated and experimental results was within 5%, highlighting the accuracy of the thermal model developed. This study contributes to the limited literature on friction welding of 15CdV6 steel and offers a reliable approach for predicting weld temperatures using numerical simulations.
