有关 CO_2熔化极气体保护焊的文献已有很多报导。关于这个方法的原理以及这种方法大量地用来代替其它焊接工艺的原因也无须再加以累述。事实上,CO_2熔化极气体保护焊多年来已经成功地应用到金属制作工艺中,其范围涉及到管路焊接、汽车制作、不锈钢及镀层钢的焊接、点焊及大型运土设备的熔焊等等。无论是采用短路过渡、射流过渡还是点焊,CO_2焊接均广泛地代替了氧乙炔及手
There have been many reports on the literature about CO2 gas shielded welding. The principle of this method and the reason that this method is used in large quantities to replace other welding processes need not be recoded. In fact, CO 2 GIG welding has been successfully applied to metal fabrication processes over the years, ranging from pipe welding, automotive fabrication, to the welding of stainless steel and coated steel, to spot welding, and to the welding of large earth-moving equipment Wait. Whether it is the use of short-circuit transition, jet transition or spot welding, CO_2 welding are widely replaced by oxyacetylene and hand
