The joining phenomena during the friction process of pure titanium (Ti) and pure copper (OFC) friction welding was investigated. When the joint was made at a friction pressure of 60MPa or lower, the OFC side was deformed from both weld faying surfaces contacting. Then, the joint generated the sparkle from the Ti side with increasing friction time. The peripheral portion of the Ti side was heavily deformed and intensely upset when it had the sparkle. On the other hand, the joint did not have the sparkle of the Ti side when it was made at a friction pressure of 75MPa or higher. The deformation of the OFC side was large and intensely upset. The fact that the joining phenomena had dissimilarity was due to the difference of the yield strength at the temperature in the friction process.
