If carbon dioxide gas shielded welding stainless certainly use stainless steel wire, gas also with the mixed gas, the content of the reactive gas does not exceed 5%, can also be used does not exceed 2% of the oxygen flux cored wire, or in conjunction with a common gas mixture also the same can be stainless steel welding If the carbon dioxide gas shielded welding stainless steel and carbon steel, stainless steel wire, stainless steel wire, we have to take special protective gas ibid; Also, if a good welder, such as gas welding of non-NBC, basically can be welded stainless steel, of course, to adopt or dual pulse would be more perfect. If carbon dioxide protection of welded steel, of course, can also be stainless steel wire, welding, shielding gas Ibid; benefits of doing so is the weld line input less energy, reduce the heat affected zone of the weld, lower weldment deformation, the drawback is the price of stainless steel wire carbon steel wire several times, another case of welding alloy steel or high-strength steel, the strength of the weld and base metal quite different
