Abstract

In a friction stir joining apparatus la members 20, 30 subjected to friction stir joining are fixed on a table 5. A joining head 200 which moves in direction A has a rotary tool 10 which performs the friction stir joining to form a joining bead 50. A sensor 210 irradiates a light beam 212 and detects edge portions of the members, to control the joining head 200 position. A cutting means 12 on the rotary tool 10 cuts off a burr, and forms chips. An air jet injected from an air nozzle 240 prevents entry of the chips 60 to the sensor 210.

Description

technical field [0001] The present invention relates to a manufacturing method of a structure and a manufacturing device of a structure, in particular to a friction stir joining method of a structure and a friction stir joining device of a structure. Background technique [0002] Two members to be subjected to friction stir bonding have a raised portion at one end thereof, the two members are approached and a rotary tool is inserted from one side of the raised portion, and then a friction stir joining is performed. In the friction stir joining, when there is a gap between the two members to be friction stir joined, a reduced thickness of the two members to be friction stir joined is compensated for. [0003] After the friction stir joining, when the raised portion of the two elements to be friction stir joined is unnecessary, the raised portion is cut or canceled and the cut or canceled raised portion is removed, and formed flat An outer surface of a component to be frictio...
