我厂以及同行业单位以往均采用手工电弧焊或气焊来焊接电力电容器箱盖。由于电焊和气焊的热影响区较大,会把箱盖上用锡焊好的瓷套熔下来,因此只好先焊盖后焊瓷套,这样就造成了工艺流程的倒转。一台电容器将近20公斤,每天平均二、三百台,往返搬运,劳动强度很大,人力和场地也占用很多,又不利于机械化和自动化,影响了生产的进一步发展。为了 I plant and the same industry units in the past are using manual arc welding or gas welding to weld the power capacitor box lid. Due to the large heat affected zone of welding and gas welding, the cover will be melted down with a good porcelain sleeve, so the welding sleeve must be soldered first, which will result in the reversal of the process flow. A capacitor of nearly 20 kilograms, an average of two or three hundred a day, from time to move, labor intensive, manpower and space also occupy a lot, but also not conducive to mechanization and automation, affecting the further development of production. in order to
