Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brazing device for a multi-

The present invention relates to a brazing apparatus and a brazing method using the brazing apparatus. More particularly, the present invention relates to a brazing apparatus and a brazing method using the brazing apparatus. More particularly, And a brazing method using the brazing device.

Instead of melting and bonding the base material to bond the two separated base materials together, the brazing is completed by supplying and melting the brazing material (brazing filler metal) melted at a temperature lower than the melting point of the base material between the separated base materials Welding method.

Generally, this is a welding method which is applied when the productivity is enhanced by torch heating or by joining a plurality of parts at the same time in a vacuum heating furnace, or in the case of heterogeneous bonding or the nature of a product, it is difficult to apply another melting welding method such as arc welding.

In general, brazing is widely used as a method of joining two base materials to be bonded at a temperature of 450 ° C or higher by adding a flux at a melting point or lower.

That is, in brazing welding, an insertion metal such as silver solder is inserted between a base metal and a base metal to be welded, and then the inserted metal is heated and melted to bond the base metal and the base metal.

Such brazing welding is advantageous in that the bonding between the dissimilar metals and the dissimilar materials can be easily performed because the heat is little affected by the base material, since the base material is hardly melted and bonding is performed at a low temperature.

In addition, since brazing welding can precisely join very small parts or complicated parts, sealing and joining can be performed in an airtight state, and automation is easy, so that many applications as a joining technique are possible.

Brazing welding, which is widely applied as a welding technique, is a welding method in which one contact is welded to a base material by inserting a welding agent. When welding two contacts on one side and the other side of the base material, Welding one contact after inserting the welding agent, and then welding the contact by inserting a welding agent into the other side of the base material.

Therefore, when the two contact points are welded to the base material, the contact points must be welded to the base material through two times. Therefore, there is a problem in that a lot of work is required and the welding operation time is long.

Nevertheless, there is no welding device for simultaneously joining two contact points to the base material, and in fact, the efficiency and productivity of the welding work are not greatly improved.
