我厂生产的变压器的外壳——油箱,是用钢板、钢管焊接制成。钢板厚度主要有1.5、3、4、6mm等。在油箱直缝的对接焊接中,我们采用CO_2+O_2混合气体保护自动焊的新工艺进行了试验。一、试验设备: 试验用焊机为GD—200型。焊接小车结构仿自动切割机小车,控制线路为单相半控整流电路。焊枪采用手工半自动焊枪形拉丝式焊枪,导丝管为鹅颈形。焊枪与工件间的距离及水平仲缩距离用齿条调
I plant the shell of the transformer - the tank is made of steel, welded steel pipe. Thickness of the main plate 1.5,3,4,6 mm and so on. In the butt welding of the straight seam of the fuel tank, we tested the new technology of CO 2 + O 2 gas mixture protection automatic welding. First, the test equipment: test welder GD-200 type. Welding car structure imitation automatic cutting machine car, control circuit for the single-phase half-controlled rectifier circuit. Welding torch using manual semi-automatic welding wire drawing torch, wire guide tube for the gooseneck. Torch and the distance between the workpiece and the level of contracted with the rack tune
