Effect of Laser Heat Treatment on the Mechanical Performance and Microstructural Evolution of AISI 1045 Steel-2017-T4 Aluminum Alloy Joints during Rotary Friction Welding

Abstract:

This paper evaluates the influence of laser power on the rotary friction welding (RFW) process to improve the mechanical performance and microstructural evolution of AISI 1045 steel and 2017-T4 aluminum alloy joints. As part of this evaluation, the absolute chemical determination of these materials was precisely measured using a GDOES bulk analysis. The application of laser power during friction welding is known as laser-assisted friction welding. To evaluate the effect of the energy from the laser on the rotary joining process of steel-aluminum, a laser-assisted rotary friction welding process was set up, and a design of experiments (DOE) applied. First, a DOE consisting of two factors at two levels was used to evaluate the effect of friction pressure and rotational speed on the hardness and tensile strength of the weldment. Then, a mixed DOE of three factors at two and three levels was implemented to …
