ABSTRACT Friction welding is a method of joining materials caused by friction between two materials which utilizes the heat of friction between the two materials, the same or different. This study aims to determine the effect of rotational speed on dissimilar materials on the weld area and hardness values. There are various methods to overcome problems in the process of joining the material, i…
