Recently aluminum alloy was widely used for several transportations and constructions because of the recycling. Spot joining like resistance spot welding, rivetting were used in the automotive industries has problem such as costs and qualities. Friction Spot Joining robot system was developed by applying frictional heat to solve several problems.11th RSJ Technical Innovations Award in 2006. 第35回日本溶接協会技術賞本賞 in 2004. 第33回日本産業技術大賞審査委員会特別賞 in 2004.
