电机结构中有用鋼板卷成圆筒作主体的,这类圆筒外径一般为200～800公厘,厚度10～24公厘以及不同的长度。焊接这种直缝,我们采用了简易焊剂垫上自动电焊(见图1)。卽利用了圆筒本身的重量作为焊剂对工件的压力,这样便不需要复杂的压缩空气装备了,所以准备工作很简单,适于大量生产。焊前把焊剂撒装在焊剂垫槽内,焊剂必须高出槽堆成尖端小山。把工件用专线电葫蘆或吊车吊上焊剂垫上,使焊缝中心和焊剂垫尖端时正(平行),放下工件,这样
Useful structure of the motor coil into the cylinder as the main body, the outer diameter of such cylinders are generally 200 to 800 mm, thickness 10 to 24 mm and different lengths. Welding this straight seam, we use a simple flux pad automatic welding (see Figure 1).卽 The weight of the cylinder itself is used as the pressure of the workpiece on the flux. This eliminates the need for complicated compressed air equipment, so preparation is simple and suitable for mass production. Solder flux before welding solder pad installed in the tank, the flux must be higher than the tank pile tip hill. The work piece with a special hoist or crane hanging on the flux pad, the weld center and the flux pad tip is (parallel), put down the workpiece, so
