| titleOfInvention | Friction stir welding method and device for structural steel |
| abstract | The present invention is to provide a friction stir welding method in which, in particular, strictly control the preheating process conditions, and realize the same, in order to eliminate poor plastic flow due to insufficient heating of the material to be processed and to achieve sufficient strength and improvement in joining workability. The device is the subject. During friction stir welding of steel plates ( 3 , 3 ) as workpieces, a pair of rotating tools ( 1 , 15 ) facing each other are inserted into the steel plates ( 3 , 3 ) from both the one surface side and the other surface side. The unjoined portion is moved in the joining direction while being rotated, and the steel plate (3, 3) is heated by a heating mechanism (5) provided in front of the rotary tool (1, 15) to perform a preheating treatment process, which is strictly The composition of the opposing pair of rotating tools (1, 15) and the surface temperature, area and position of the heating zone in the preheating process are controlled independently. |
