近年来,我国对真空电子束焊机的研制工作已有了一定的进展,先后研制成功了几种类型的电子束焊机。但是,几乎所有国产电子束焊机均采用二极电子枪。由于二极电子枪存在一些缺点。因此,我厂从一九七七年开始研制60千伏直热式三极电子枪。通过几年来的反复摸索与试验,已基本研制成功。经过一年多的产品工艺性试验与考核,证明三极枪性能良
In recent years, China’s vacuum electron beam welding machine has been developed to a certain extent, has successfully developed several types of electron beam welding machine. However, almost all domestic electron beam welding machines are used two-pole electron gun. Due to some disadvantages of the bipolar gun. Therefore, our factory started to develop the 60 kV direct thermal three-pole electron gun from 1977. Through several years of repeated exploration and testing, has been basically developed successfully. After more than a year of product technology test and assessment to prove that the three-pole gun performance is good
