PROBLEM TO BE SOLVED: To shorten working time by joining the upside and the underside at the same time in the case members are joined by friction welding. SOLUTION: A first panel 56 and a second panel 57 are butted and the respective panels have a first plate and a second plate and a third plate which are connected to both ends of the first plate. The second plate and the third plate are substantially parallel and the first plate is substantially crossed with the second plate and the third plate at right angles and the first plates are butted each other. Rotary tools 50, 50a are respectively arranged on the sides of the second plate and the third plate of the butt part and also the rotary tool 50a on the other side is arranged in the vertical direction of the rotary tool 50 on one side. The friction welding is performed by moving two rotary tools substantially at the same speed. COPYRIGHT: (C)2006,JPO&NCIPI |
