Problems solved by technology

Therefore, it is difficult to maintain the brazing space uniformly in brazing, and since the brazing space is not uniform, the infiltration of the filler metal cannot be performed accurately, and therefore, there is a problem of lowered joint strength due to variations in the brazing area

Abstract

A brazed tube assembly and a joining method thereof using brazing, are disclosed. The tube assembly using brazing includes a pre brazed joint assembly method to form a fully pre assembled and locked component prior to brazing. This involves a metal tube with a binding bent portion which is disposed at a lower portion of the basic metal tube bound using brazing to be bent toward an outer periphery,a connecting part to form a binding installation portion with an installation bent portion which is disposed at an upper portion of the connection tube to be bent toward an outer periphery to installthe binding basic metal part of the basic metal part, and to form a combining projection upward at an outer end portion of the binding installation portion, and a binding part to form a wetting spaceat an upper end portion of the binding bent portion of the basic metal part which is in surface contact with the combining projection, wherein filler metal is heated for wetting in a gap between theconnecting part and the basic metal part in an installation state to form a filler metal layer which binds the basic metal part and the connecting part.

Description

technical field [0001] The invention relates to a brazing pipe assembly and a method for assembling the brazing pipe assembly using brazing. Background technique [0002] In general, brazing is a joining method that allows the brazing of parent metals of the same type or of different types without damage by adding a filler metal at a temperature lower than the melting point of the two parent metals to be brazed. The base metal, the parent metal will be brazed at a temperature of 450°C or higher. Brazing is a widely used method in industrial fields involving vehicles, aircraft, nuclear industry, air conditioning equipment, refrigerators, carbide tools, defense industry parts, water pipe fittings, electrical and electronic equipment, agricultural implements, household appliances, etc. Joining method. [0003] The advancement of brazing technology is one of the reasons for the rapid development of the industry. In particular, brazing technology is widely used in aerospace in...
