Title: Friction stirring type jointing method
Inventor: ESUMI MASAKUNI
IPC: B61D17/08
Filed: 2001-08-24
Abstract: PROBLEM TO BE SOLVED: To provide a method for enabling a desirable friction stirring type jointing when an angle of a joint line significantly changes. SOLUTION: When jointing a coaming 120 of a port opening 110 and a plate 11(21) by using friction stirring method, a rotating tool 200 is shifted along the coaming 120. This rotating tool 200 is sloped away from its moving direction. When the friction stirring type jointing begins with a right piece 120R up to a corner section P5 from the right piece 120R to a central piece 120C, the rotating tool 200 is pulled out of both the coaming 120 and the plate 11(21). Then the rotating tool is sloped towards its moving direction along the central piece 120C. Subsequently the rotating tool is sent down and inserted into the coaming to start the friction stirring type jointing. This prevents the rotating tool from turning over as it is inserted into the coaming 120, therefore a desirable friction stirring type jointing can be achieved without causing excessive frictional heat.
