Application of Clad Brazing Materials

Abstract

Fabrication of high-density heat exchangers, which have a large heat transfer area and a compact size, is best accomplished by brazing where the brazing filler metal is clad to the materials to be brazed. This article focuses on the brazing procedures involved in the fabrication of high-density heat exchangers. The brazing procedures include base metal and brazing filler metal selection; fabrication of clad brazing materials; and stamping, cleaning, and assembling of cladded parts. The article concludes with an examination of brazing parameters.
