一、前言在我国的中、低压锅炉和压力容器制造行业中,手工碳弧气刨由于在降低劳动强度、提高劳动生产率、减少噪音等方面的优点,得到了很多工厂的广泛采用,作为一种工艺手段取代了风铲进行挑除焊根的工作。但是,手工碳弧气刨存在着刨削质量不够稳定:刨削的沟槽轨迹易于偏离 I. Introduction In China’s medium and low pressure boilers and pressure vessel manufacturing industries, manual carbon arc gouging has been widely adopted by many factories due to its advantages in reducing labor intensity, improving labor productivity, reducing noise, etc. Technological means to replace the wind shovel to remove the root work. However, the manual carbon arc gouging planing quality is not stable enough: gouged trench trajectory easy to deviate
