PURPOSE:To obtain the fine joining strength by fitting a second member with a different melting point from a first member in a close state in a fitting hole of the first member and filling powder metal in a reservoir part formed on one member at least of both members to join these members by using a laser beam. CONSTITUTION:The first member 1 and the second member 2 with the different melting points are fitted in the close state via the fitting hole. A slurry body 5 which is formed by dispersing the powder metal in liquid paraffin is applied to the reservoir part which is obtained by forming a notched part on both the members 1 and 2. The laser beam is projected on this part to which the slurry body is applied in a spot-shape to join these members together. By this method, the fine joining strength can be obtained. |
