| Outline of Final Research Achievements |
Development of friction butt welding, which is a new butt welding process using a consumable tool, based on principle of friction surfacing, has been challenged in this study. Al alloy 5052 was welded using the friction butt welding process at various process parameters, and then effect of process parameters on separation and filling of the consumable tool, and microstructure and transverse tensile properties of the weld were systematically examined. The present study suggested that friction butt welding had the high potential as a new butt welding one although the further optimization of process parameters was required to produce the weld with the strength close to that of the base material.
