Document Type and Number:

Japanese Patent JP7273705

Kind Code:

B2

Abstract:

To provide a distance measuring device, friction stir joining apparatus and friction stir joining method which can perform the high quality joining to a workpiece having the large variation in the surface height.SOLUTION: A distance measuring device includes: a measuring mechanism which has a contact part contacting a shoulder surface of a joining tool for friction stir joining, a tip part movable in the first direction connecting the surface of a workpiece and the shoulder surface in the state of contacting the surface of the workpiece, a detector detecting the position in the first direction of the tip part and an output unit outputting data of the position in the first direction of the tip part detected by the detector; and a control unit which calculates the position of the tip part with respect to the contact part from the data of the position output from the output unit and calculates a distance between the shoulder surface of the joining tool and the surface of the workpiece.SELECTED DRAWING: Figure 1
