Title: Friction stir welding method and reforming method thereby
Inventor: FUJITANI YASUYUKI
IPC: B23K103/04
Filed: 2004-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To make welding and surface layer reforming possible by friction stir for a workpiece composed of a high melting point material, in a friction stir welding method in which a workpiece is welded through plastic flow by frictional heat produced between a rotary tool and the workpiece by inserting the rotary tool into the workpiece and rotatably moving it.  <P>SOLUTION: Welding or reforming by friction stir is performed with a weld zone s heated by irradiating it with a laser beam, or with an insert 3 placed between welding faces, or with the above two means combinedly used. Irradiation of the laser beam fluidizes even a high melting point material. Also, placing the insert between the welding faces causes adiabatic effect to be imparted between the insert and the workpiece, preventing the frictional heat from diffusing.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
