在毛主席革命路线指引下,我们从一九七二年开始应用等离子弧焊接技术,先后改装了焊接设备,改进了转具及各种控制系统,比较稳定地掌握了直缝和4～6毫米环缝的焊接规范。为了适应科研产品的急需,我们在吸取兄弟单位有关经验的基础上,又以较快的速度突破了8毫米环缝焊这一技术关键,初步摸索到一些经验。现小结如下,仅供参考。一、存在的主要问题大家知道,环缝焊区别于直缝焊的主要特点是必须首尾相接,收弧处与起弧处要搭接重
Under the guidance of Chairman Mao’s revolutionary line, we started to apply plasma arc welding technology in 1972. We have successively modified the welding equipment, improved the transfer tools and various control systems, and have mastered straight stitches and 4 to 6 mm Girth welding specifications. In order to meet the urgent need of scientific research products, we draw on the experience of brothers units, but also a faster rate of breakthrough 8 mm girth weld the key to this technology, some preliminary exploration to some experience. Now summarized as follows, for reference only. First, there are the main problems As you know, ring seam welding is different from the main features of straight seam welding must be connected end to end, arc at the arc with the starting point to lap weight
