    Abstract: The gas-metal arc welding of metal-core wile electrodes in the pure Ar shielding gas for carbon steel, low alloy steel, and ferritic stainless steel is described. Such shielding gas provides several benefits not realized ??the gas-metal arc welding process with solid wires. When compared to standard argon/oxygen containing gas mixtures normally used for metal cored wires, these benefits include reduced silicate islands on the weld surface for improved weld appearance, reduced welding fume, and lower weld spatter, all of which provide easier clean-up after the welding operation. Benefits also include reduced arc penetration desirable for welding on thinner materials or handling poor joint fit-up. Lower voltage requirement further makes it possible to weld on thinner materials. Lower oxygen content in the weld deposits provide better toughness and easier welding in all-positions.

    Abstract translation: 描述了用于碳钢,低合金钢和铁素体不锈钢的纯Ar保护气体中的金属芯焊丝的气体 - 金属电弧焊接。 这种保护气体提供了几条不实现的优点,气体 - 金属电弧焊接工艺采用实心线材。 当与通常用于金属芯线的标准氩/氧气混合物相比时,这些优点包括在焊接表面上减少的硅酸盐岛,以改善焊接外观,减少焊接烟雾和降低焊接飞溅,所有这些都提供更容易的清理 焊接操作。 优点还包括在更薄的材料上焊接或处理较差的接头装配时所需的减少的电弧穿透。 较低的电压要求进一步使得可以在更薄的材料上焊接。 焊接沉积物中较低的氧含量可提供更好的韧性,更易于焊接在所有位置。
