Abstract
Brazed structures comprising hollow components having a closure component bonded thereto by a metallic brazing alloy for closing off an end of the hollow component are disassembled by locating a wire transport material in the hollow component and covering the open face of the hollow component with a wire fiber material. Heat is then applied to liquefy the brazing alloy which is drawn up into the metal wire fiber material by capillary affect created by the wire transport material.
Claims14
A process for disassembling a brazed structure comprising a hollow component having at least one hollow element and a closure component bonded thereto by a metallic brazing alloy for closing off an end of the at lest one hollow element so as to define therewith an open faced cell, comprising the steps of:
- (a) locating in the cell a wire transport material;
- (b) covering the open faced cell with a metal wire fiber material which penetrates the cell and contacts the wire transport material;
- (c) heating the hollow component to sufficient temperature wherein the metallic brazing alloy flows through the wire transport material and onto the metal wire fiber material;
- and
- (d) separating the hollow component from the closure component.
