<P>PROBLEM TO BE SOLVED: To provide a passage built-in mount with a constitution where the generation of cracks in a welding line surrounding a groove and the corrosion of the welding line are prevented, and the sealing function of the welding line can be maintained, and to provide its production method. <P>SOLUTION: A plate 22 and a plate 23 are welded in such a manner that a groove 24 is surrounded by friction stir welding to form a welding line 28, and, in the space between the groove 24 and the welding line 28, a brazing filler metal 30 provided between the plate 22 and the plate 23 is melted with friction heat at the time when the welding line 28 is formed by the friction stir welding, thus the plate 22 and the plate 23 are brazed. Alternatively, a thermosetting adhesive is used instead of the brazing filler metal, and the thermosetting adhesive is set by the friction heat. Alternatively, a plurality of grooves 24 are surrounded by the welding line 28, and the plate 22 and the plate 23 are spot-welded at the central part within the welding line. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
