金属罐的焊接,特别是立缝和横缝,多年来都是手工焊,设备多,速度慢,劳动强度大,远远跟不上油田建设发展的需要。为了加速建罐速度,改变焊接落后面貌,我们进行了立缝和横缝自动焊接的试验。立缝的自动焊接,难度较大,没有专用焊机,是很难实现的。鉴于气体保护焊对自动焊接立缝具有一定的有利条件,故在原有二氧化碳气体保护焊管机的基础上,进一步改装成二氧化碳气体保护双枪立焊机,并在油田新开发 The welding of metal cans, especially vertical stitches and horizontal stitches, has been made by hand over the years with many equipments, slow speed and labor intensity, far behind the needs of the construction and development of oil fields. In order to speed up the construction of cans and to change the backwardness of the welding, we conducted the tests of vertical and horizontal joint automatic welding. Stand seam automatic welding, more difficult, there is no special welder, is difficult to achieve. Since gas shielded welding has some favorable conditions for automatic welding standing seam, it is further modified into a carbon dioxide gas protection double gun welding machine on the basis of the original carbon dioxide gas shielded welding pipe machine and is newly developed in the oilfield
