PURPOSE: To set easily and uniformly only the required amt. of a brazing filler metal in the joint part between the projecting bottom surface of a base material and a plate-shaped member by disposing the wire-shaped brazing filler metal along the joint part, bending both ends of the brazing filler metal to the other side face side and setting the metal.
CONSTITUTION: The joint part S of a plate-shaped member 2 is tack-welded at an angle to the projecting bottom surface 1a in the lower part of a base material 1, then a wire-shaped brazing filler metal 3 is cut to a suitable length and is curved in contact with the one side face 2a of the member 2 and along the part S; further both end parts 3a, 3a thereof are bent to the other side face 2b side of the member 2 at both top ends of the part S. The material 1 and the member 2 set with the metal 3 in the above-mentioned way are put into a furnace and are heated, by which the metal 3 is melted and is penetrated uniformly into the part S. Brazing is surely accomplished at the top end of the joint part S by the metal 3 provided along both side faces 2a and 2b.
