Abstract

The invention discloses an electromagnetic vibrating, stirring and friction-welding stirring-head and a corresponding welding method thereof. An electromagnetic vibrating device is adopted to assist electromagnetic vibration during the process of stirring, and friction-welding to lead the stirring-head to vibrate at high frequency simultaneously when the stirring-head rotates at a high speed to transfer energy to the metals in a stirring and friction area so as to lead the metals to achieve plastic state more quickly; the thermoplastic metals receive the composite effects of a friction force and the high-frequency vibrating energy during the rotating process of a stirring needle, thus being capable of effectively improving the velocity of the thermoplastic metal flow, improving the forming efficiency and quality of welding seams and being more effectively used for the welding and processing of high-melting point materials and thick boards.

Description

technical field [0001] The invention relates to the field of metal welding, in particular to an electromagnetic vibration friction stir welding stirring head device and a corresponding method. Background technique [0002] Friction stir welding (hereinafter referred to as FSW) is a patented solid-phase joining technology invented by the British Welding Institute in 1991. It is called "the most revolutionary welding technology" by the industry and has broad application prospects. The welding process of friction stir welding is that a cylindrical welding pin (welding pin) extends into the joint of the workpiece, and through the high-speed rotation of the welding pin, it rubs against the material of the welding workpiece, thereby increasing the temperature of the material at the joint Soften and at the same time perform friction stir on the material to complete the weld. At present, FSW has been successfully applied in the connection of non-ferrous metals, and some progress ha...
