| Abstract |
This paper describes a fundamental investigation of the friction welding condition for the pure copper/ pure titanium joining and the effect of friction time, upset pressure on the mechanical and metallurgical properties of the joint. Taguchi method has been adopted for investigating the contribution of welding variables. Under a constant upset pressure, the tensile strength have a little difference with an increase in friction time. At a constant friction time, the tensile strength increased with an increase in the upset pressure. The tensile fracture of Cu to Ti joint occurred at the Cu base material near the interface. |
