利用真空电子束进行焊接,是焊接领域巾新型技术之一。由于它具有一系列的优点,在国内外都给予足够的重视,目前电子束焊已迈出航空、原子能、电子等尖端工业部门,在其他一般工业部门也开始应用。我厂在成都电焊机研究所帮助下,采用真空电子束焊接法对我厂修理件——垂直活动铰接销(以下简称铰接销)进行焊接修理。目前已焊了两批共22件,其中10件经检验合格已用于生产。领先使用的4件,使用时间已超过100小时,经检查情况良好,可继续使用。
Welding using vacuum electron beam is one of the new technologies in the field of welding. Because it has a series of advantages, both at home and abroad have given sufficient attention, the current electron beam welding has taken aviation, atomic energy, electronics and other cutting-edge industrial sector, in other general industrial sectors have begun to apply. I plant in Chengdu, with the help of welding machine research, the use of vacuum electron beam welding method I plant repair parts - vertical hinge pin (hereinafter referred to as hinge pin) for welding repair. At present, two batches have been welded in total of 22 pieces, of which 10 pieces have passed the inspection and have been used for production. Leading use of 4, the use of time has more than 100 hours, after checking the good condition, can continue to use.
