Abstract

The invention provides a stirring head for friction stir welding of a fillet joint, relates to the technical field of friction stir welding, and solves technical problems in the prior art that a toolfor friction stir welding of a fillet joint is complicated in operation and small in application range. The stirring head comprises a connecting head, a shaft shoulder (13) and a stirring pin (14), wherein the shaft shoulder (13) and the stirring pin (14) are sequentially arranged below the connecting head; the shaft shoulder (13) is arranged in the way that the diameter of the shaft shoulder is gradually reduced from a connecting face with the connecting head to a direction of the stirring pin (14); and a spiral groove (131) is formed in a side surface of the shaft shoulder (13) from the connecting face with the connecting head to the direction of the stirring pin (14). The stirring head is of a simple integrated structure, and solves the problem of much assembly demand caused by use of astatic shaft shoulder stirring head; and by use of the stirring head provided by the invention, a plate to be welded does not need to be specially machined and is directly spliced into the fillet joint for welding.

Description

technical field [0001] The invention relates to the technical field of friction stir welding, in particular to a stirring head for friction stir welding of fillet joints. Background technique [0002] Since friction stir welding came out in the early 1990s, because it is particularly suitable for welding non-ferrous metals such as aluminum alloys, friction stir welding technology has continued to develop. Friction stir welding is a solid-phase welding method, which has the advantages of high joint quality, high welding efficiency, environmental protection, and low cost. It is known as another welding technology revolution after laser welding. However, any technology is not omnipotent and has its adaptability. Friction stir welding requires rigid support and firm clamping during the welding process. It is not suitable for fillet joints and space welding, and is not suitable for high melting point metals. It requires assembly accuracy. High disadvantage. [0003] The applica...
