Abstract
A TIG welding flux for dissimilar steels is used to solve the problem that the conventional friction stir welding procedure for butt-joint welding a stainless steel workpiece and a carbon steel workpiece cannot be used on site, as well as the problem that the increased operating time and manufacturing cost due to forming bevel faces on both the stainless steel workpiece and the carbon steel workpiece. The TIG welding flux for dissimilar steels includes 25-35 wt % of silicon dioxide (SiO), 20-30 wt % of cobalt (II, III) oxide (CoO), 15-20 wt % of manganese (II, III) oxide (MnO), 10-15 wt % of nickel (III) oxide (NiO), 7-12 wt % of molybdenum trioxide (MoO), 6-11 wt % of manganese (II) carbonate (MnCO), 5-10 wt % of nickel (II) carbonate (NiCO), and 2-4 wt % of aluminum fluoride (AlF).
