CO_2气体保成护焊具有生,产率高本低,焊接质量好,变形小,焊缝成型美观,无渣壳,操作简单,能全位置焊接等优点,是一种先进的焊接工艺,已在国内造船,化工,石油,机械及国防工业等各行业中逐渐推广使用,并越来越显示出它的优越性了。近年来,我厂曾试验或在生产中使用了CO_2气体保护管状焊丝半自动焊,Ar气、CO_2气混台气体保护半自动焊,以及Ar气、CO_2气混合气体保护窄间隙粗丝自动焊等,在生产中发挥了一定的作用,深受工人群众的欢迎,初步尝到了甜头。一、CO_2气体保护焊在锅炉设备结构件上的应用实例我厂金结车间是制造锅炉设备中各种钢结构件的冷作车间,产品有锅炉的钢架、燃烧设备、烟风道和予热器等,这类
CO_2 gas holdup welding is a kind of advanced welding process with high yield and low cost, good welding quality, small deformation, beautiful weld appearance, no slag shell, simple operation and full position welding. In the domestic shipbuilding, chemical, petroleum, machinery and defense industries and other industries gradually promote the use, and more and more to show its superiority. In recent years, our factory has used semi-automatic welding of CO 2 gas-shielded tubular welding wire, semi-automatic welding of Ar gas and CO 2 gas mixed with gas, and narrow gap thick wire automatic welding of Ar gas and CO 2 gas mixed gas protection. In production played a certain role, welcomed by the workers, the initial taste of the sweetness. First, the CO_2 gas shielded welding equipment in the boiler structure of the application examples Our factory is the junction of the manufacturing plant in the boiler equipment, a variety of steel structure of the cold workshop, the product has the boiler steel frame, combustion equipment, smoke duct and to Heaters, etc., this type
