摘要： PURPOSE:To make repairing again easily and firmly even when the first joining is failed by making the repairing by attaching annular solder to the tip of a sleeve and reheating and soldering. CONSTITUTION:Annular solder 5 having incorporated flux is mounted to the upper part of the sleeve 1. A part of the circumference of the solder 5 is cut obliquely, and the solder can be inserted into the tube easily making the diameter of the solder small within the limit of elasticity. By heating, the flux 8 flows along inside face of the tube 2, and cleans the soldered part. By plating the outer surface of an end of the sleeve 1 with the solder, the sleeve 1 and the tube 2 are soldered by the length of plating even when the sleeve 1 is in close contact with the tube 2.

The metallic sleeve 2 which has installed a brazing material 3 to the groove (a) is installed to a position covering a rejected part (c) of a heat transmission pipe 1 of a heat exchange pipe. Subsequently, a pipe is expanded by applying a pressure 4 to the thermal spraying part (b), and the inside surface of the pipe 1 and the outside surface of the metallic sleeve 2 are adhered tightly and held. Next, the brazing material 3 is heated so as to become higher by about 30-50 deg.C than a melting temperature by a heating device 5.
