本発明は、隙間（クリアランス）のない嵌め合い継手部
をろう付接合するようにしたろう付方法に関する。DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a brazing method for brazing fitting fitting joints having no clearance.

継手部では、充分なろう付品質が得られない問題があっ
た。In the conventional brazing method, as shown in Figure 5, there is a gap (clearance) 9 in the brazed joint, and when molten solder flows into the gap, capillary development occurs and the gap 9 is filled with wax. Brazed joints were performed by solidifying the molten solder in this state. However, there has been a problem that sufficient brazing quality cannot be obtained in a fitting joint portion without a gap.

しい治具を使用する方法では、量産に適さない。In the conventional method, there is a gap (clearance) at the joint,
The joint will become eccentric or fall by the amount of the gap, so if the joint has strict dimensional quality requirements, cut the joint with great care and then fix it using a fixing jig. Although the dimensional requirements were met, the brazing metal processing temperature (approximately 1100℃) was high and the jig was subject to thermal expansion and thermal deformation.
It appears that the dimensional requirements of the joint are not satisfied. Furthermore, the method of using a new jig each time is not suitable for mass production.
本発明は、上記問題点を解消し、容易に高品質のろう付

時に満足させることができる。For brazing without any clearance, before fitting, as shown in Figure 4, mark scratches 5 across the machined surface line (machine groove) 10 and in the direction of the playback so that it leads to the outside. establish. Due to these two factors (fitting without gaps, scribing scratches), dimensional quality and brazing quality can be satisfied at the same time.

ぶ。FIG. 1 is an explanatory diagram showing an example of the brazing method according to the present invention. In the figure, the female side part 1, the male side part 2, the assembly before brazing 3, and the brazed joint 4 are shown, and the male side fitting dimension 8 is larger than the female side fitting dimension 7. . Also, several scratches 5 are provided on the joint portion of the male part 2. Next, they are fitted together by a cold fitting method, a shrink fitting method, or a press fitting method so as to become an assembled product 3 before brazing. Thereafter, the brazing material 6 is placed on one end of the joint, heated to an appropriate temperature, and brazed phase welded, thereby producing the brazed joint 4. In this case, the solder recovery part covers the entire area of the fitting part, and in addition to the marking scratches 5, it also extends to the machine groove 10.
