Electron beam welding of dissimilar materials and image acquisition

Abstract

Use of electron beam welding method for welding dissimilar materials of nitrogen steel and armor steel is proposed in this article. Used high energy electron beam as heat source, by means of welding experiment, the welding performance, joint microstructure, hardness which all had been tested, experimental results show that main organization of the weld zone is dendrite, main components between dendrite is low melting phase and impurities, hardness of the weld zone is higher than two kinds of steels, heat affected zone of armor steel is highest. Experiments had also established a visual collection system, image of electron beam welding of two dissimilar steel had been collected and processed, which can provide a reference for future research in this area.
