Abstract

PURPOSE:To braze securely members having different coeffts. of thermal expansion to each other in the stage of brazing metallic members to each other or ceramics and a metal at joint surfaces by interposing a brazing filler metal on the joint surfaces of both members and conducting directly electricity to the brazing filler metal to melt said material. CONSTITUTION:Foil, wire or the like of a conductive brazing filler metal 3 or the powder thereof together with said foil and wire are inserted between metallic members 1 and 2 and are pressed from above then electricity is directly conducted to the material 3 to melt said material and to braze the members 1, 2 in the stage of joining the members 1, 2 by brazing. If one 1 of the members to be brazed is a ceramic material and have no wettability with the molten brazing filler metal, a metallized layer 3 is preliminarily formed on the joint surface thereof then an insert layer 4 sandwiching conductive metallic foil 6 of copper, etc. by a brazing filler metal 5 is placed between the same and the other metallic member 2 to be joined and electricity is conducted to the foil 6. The material 1 and the member 2 are then easily brazed by the metal 5 even if the metal 5 has poor conductivity.

Description

【発明の詳細な説明】 本発明は、二部月のロー付方法に関するものである。[Detailed description of the invention] The present invention relates to a method for brazing a two-part moon.

違いがあると、冷却途上で。
The common method for making ``roi'' is to sandwich the roi material between the joints,
The soldering material is heated in a furnace to its melting temperature and joined. Therefore, with this method, if there is a large difference in the coefficient of linear expansion of the bonded members, it will cause a difference in the coefficient of linear expansion during cooling.

剥離や亀裂が発生する。このために、線膨張係数の近似

Peeling or cracking occurs. For this reason, selecting a mating material with a similar coefficient of linear expansion is an essential condition.

Furthermore, even if this condition is satisfied -C, if other thermal properties (for example, specific heat -) are significantly different, thermal stress is likely to occur during cooling.1. This one is also a big problem.

欠点がある。
Also, in the method of brazing by directly applying electricity to the joining parts themselves, the joining parts themselves are directly heated, so it is difficult to prevent thermal distortion. Furthermore, there is a drawback that the bonding material is limited to conductive metals.

The present invention has been made in view of one or more of the drawbacks of the prior art, and is a novel method that can minimize the problem of thermal stress during brazing, and can also be applied to nonconductors such as ceramics. 15g of the same method is used.

The present invention first uses a conductive metal brazing material as a brazing material, and inserts this in the form of foil, wire, or powder into the joint, or together with the brazing material, conductive metal foil, etc.
Alternatively, insert the wires together, clamp and fix them with a joining member, and directly apply a current to the insert layer to selectively and rapidly heat the insert portion to melt the brazing material. The feature is that the joining members are joined by brazing.

Although the insert layer and the bonding material are electrically connected to each other, there is contact resistance between the insert material and the bonding portion, and current is difficult to branch. Furthermore, if a highly conductive material is used for the insert layer, this tendency becomes even more pronounced.

(b) Since the bonding material is not directly energized, it can be applied even if the bonding material is a non-conductive material such as ceramic. In this case, if necessary (if the o-material is ceramic/: Ar Ji), the bonding surface can be coated with metal, so that the bonding can be performed under substantially the same conditions as metal-to-metal bonding. can.
