以前我厂是采用手工堆焊的方法来修复蒸汽机车阀体和阀座的,在大搞技术革新的运动中,工人刘景林、刘玉明在技术员李济涛和苏兆波同志的帮助下,制成了一套机械化转胎,利用焊剂层下自动焊的方法使阀体和阀座等零件实现了自动化焊修,解决了效率低,质量差和劳动强度大的这一难题。现介绍如下。 In the past, our factory repaired the valve body and valve seat of steam locomotive by means of manual surfacing. In the campaign to promote technological innovation, Liu Jinglin and Liu Yuming, workers, with the help of technicians Li Jitao and Su Zhaobo, made a mechanized Tire, the use of solder layer automatically welded under the valve body and valve seat and other parts to achieve automatic welding repair, to solve the low efficiency, poor quality and labor-intensive this problem. Now introduced as follows.
