异种材料真空电子束焊接研究现状分析

Research status analysis of electron beam welding for joining of dissimilar materials

  • 摘要: 真空电子束焊接具有高能量密度、束斑直径和位置精确可控,焊接残余应力小,焊缝无污染等优点,因此,电子束焊接在异种材料连接领域的应用成为近年来研究的热点,并取得了大量的研究成果,部分已经在工业生产中得到了应用.由于电子束焊接属于熔化焊接,因此在异种金属连接中也存在冶金过程带来的困难.文中对异种材料的真空电子束焊接的研究现状进行了分析,对不同类型的异种材料接头真空电子束焊接中存在的问题和解决方法进行了总结,并提出了今后异种材料真空电子束焊接的研究重点.

     

    Abstract: Electron beam welding(EBW) in the field of joining dissimilar materials has been a subject of interest in recent years based on special features of EBW, e.g.high energy density, accurately controllable beam size and location, low residual stress and pollution-free weld.Numerous successful results have been achieved, and some of them have already been exploited in industrial production.Since EBW is a fusion welding method, difficulties associated with metallurgical phenomena still exist.This paper is aimed to have an analysis of the research status of electron beam welding for the joining of dissimilar materials.A summary of the existing problems and solutions during electron beam welding of different type of dissimilar material joint has been conducted and the key points of research in future are also proposed.
