在无产阶级文化大革命取得全面胜利的大好形势下,我厂广大革命职工意气风发,斗志昂扬,“抓革命,促生产,促工作,促战备。”的热潮一浪高过一浪,自动电弧气刨就是在这种朝气蓬勃的气纷中诞生的。过去我厂生产的石油、化工容器及其他产品,都是先由鉋床加工一道坡口,然后焊接底层焊缝,用风铲挖焊根后再焊至组装。这样生产效率远远不能满足生产发展的需要,而且铆工的劳动强度高,噪音剌耳。在返修的焊缝上用风铲返修挖掘,有些缺陷是 Under the great victory of the Great Proletarian Cultural Revolution, the vast majority of our revolutionary workers are in high spirits and high morale. The upsurge of “grasping the revolution, promoting production, promoting work, and preparing for war preparations” has come a long way. Automatic arc gouging Is born in this vibrant atmosphere. In the past I plant the production of oil, chemical containers and other products, are first machined by a bevel groove, and then welding the bottom of the weld, dig the root with a wind shovel and then welded to the assembly. This production efficiency is far from meeting the needs of the development of production. Moreover, the labor intensity of the riveting work is high and the noise is noisy. In the repair of the weld with a wind shovel rework excavation, some defects are
