Experimental Observations on Friction Weldability of Copper with Steel

摘要

In this work, friction welding was performed on Cu-Steel dissimilar metal combination. The process variables Frictionpressure, Upset pressure, Speed&Burnoff length were selected with nine samples. SEM Fractography and pittting corrosion test was also done. The material Fractrography reveals that higher tensile strength sample shows the ductile fracture with cup and cone fracture. Also power calculation was performed to find the power consumption of the machine.
