この発明は、ろう付は方法に関し、例えば熱交換器部品

法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a brazing method, for example in heat exchanger parts, and particularly to a brazing method for pasty solder goods.

である。Figure 1 is a diagram showing a conventional brazing method for heat exchanger parts, for example. In the first flash, (11 is the first member such as a cylinder, (21 is a second member such as a heat exchange pipe, which is inserted into a hole drilled in the cylinder). (3) is a wax M, 14+ are fins for heat exchange.

１ ／／′ｉろう付けされる。Here, when brazing the cylinder +11 and the heat exchange pipe (2), if the entire structure is configured as shown in Figure 1 and heated in a furnace, the brazing material (3) will melt and form the cylinder 11). The brazing material (3) enters the gap between the heat exchange pipe (2) and the heat exchange pipe (2). After this, when taken out from the furnace, the brazing filler metal (3) is cooled and solidified to form a cylinder Il+ and a heat exchange pipe +2.

穴がつ捷ることになる。However, in the conventional brazing method, the filler metal (3) is quantified in the inner cone, and furthermore, the brazing filler metal (3) is distributed evenly in the gap between the heat exchange pipe (2) and the cylinder +l+. A phenomenon that does not penetrate occurs. As a result, if there is too much brazing filler metal (3), it may flow to the bottom surface of the heat exchange pipe (21) during heating, get stuck in the surface tension, and break the hole in the heat exchange pipe (2). become.
また、ろう材（３）が少な過ぎるとろう付は接合部の気
密性が悪くなるという欠点があった。Furthermore, if the amount of brazing filler metal (3) is too small, brazing has the disadvantage that the airtightness of the joint becomes poor.

一に浸透せしめることを目的としてい′る。This invention was made to eliminate the drawbacks of the conventional products as described above, and the brazing method is such that the third member faces the second member at a predetermined distance. By embedding the brazing filler metal in the third member so as to face the third member, and then heating and melting the filler metal, the amount of brazing filler metal necessary for brazing can be embedded in the third member. The purpose is to melt and allow a certain amount of wax to penetrate efficiently and uniformly.

It is made of heat-resistant metal material.The manufacturing method is as shown in Figure 2, after fitting the hole of the ring (5) to the protrusion of the mold (6) made of Teflon, etc. Fill the solder metal (31) into the recess of the ring (6). Next, fill the wax

Even if the solder material is solidified from the beginning, the shape of the recess can be processed into various shapes depending on the required amount of brazing material and the shape and size of the brazing material. Penetrates into the location without scattering. moreover,
The member to be brazed does not have to be tubular; for example, when it is flat, it can be brazed by providing it in a recess of a constant volume to be filled with the solder 54, instead of the ring 15).
