A Study on Vacuum Brazing Procedure of Plate Heat Exchanger

Article Preview

Abstract:

The effects of work-piece heating temperature, holding time, and vacuity upon the quality of soldered fittings, when welding stainless heat exchanger (0cr17Ni12Mo2 plate) by vacuum brazing, are discussed in this paper. It also presents an optimized brazing procedure of welding heat exchanger. The processing property of soldered corrosion-resistant plate handled by the brazing procedure are discussed and optimized. Based on the analysis of samples taken from different sections of the welding seams, the paper studies the joint structure of brazing stainless steel.
