Friction welding is a method of joining two materials in solid-state that have a good bonding connection. The materials are eventually joined by continuous acts of forging pressure combined with rotational drives by varying parameters such as friction pressure, forging pressure, friction time, rotation speed and upset time. Low input heat and high contact bonding were the characteristics of this process. In this present work, micro hardness and structural analyses of friction welded joints were investigated experimentally, effect of process parameters on properties and temperature distribution were evaluated using ANOVA and were compared with Finite element analysis using ANSYS R16.2. The results were in good agreement with each other. The friction time was 5 s, the rotation speed was 2100 rpm, the friction pressure was 80 MPa, and the forging pressure was 84.5 MPa, all of which were optimal process parameters, resulted in sound joints.
