| Abstract: | Electron beam brazing parameters of stainless steel quadrate tube were decided.The microstructure of the brazed joint was investigated by means of a scanning electron microscope and an energy spectrum analyzer.The results showed that the good joint was obtained by using proper parameters.The microstructure of brazing filler metal is mostly solid solution phase.Other than austenite,copper element dissolution was found in material. |
