PROBLEM TO BE SOLVED: To prevent cracks of ceramics caused by local heating.SOLUTION: Members to be joined, junction parts of which have the same shape, are arranged axisymmetrically, and a joining device 10 joins the members to be joined in a rotated state based on a construction condition by interposing a junction medium between the junction parts of the members. The joining device includes: an irradiating part 11 which irradiates a surface of the rotating junction medium with a laser light based on the construction condition and joins the members; a measuring part 13 which measures surface temperatures of at least two points of the members; a temperature distribution calculating part 21 which obtains temperature distribution of the members based on the surface temperatures of the members measured by the measuring part; a thermal stress distribution calculating part 22 which obtains thermal stress distribution based on the temperature distribution of the members obtained by the temperature distribution calculating part; and a determination part which determines the construction condition in response to the thermal stress distribution obtained by the thermal stress distribution calculating part. |
