Abstract
A welding flux for precipitation hardening (PH) stainless steel comprises 20-25 wt % of silicon dioxide (SiO2), 20-25 wt % of molybdenum trioxide (MoO3), 20-25 wt % of chromium (III) oxide (Cr2O3), 15-20 wt % of nickel (III) oxide (Ni2O3), 4-8 wt % of aluminum oxide (Al2O3), 4-8 wt % of aluminum nitride (AlN), 4-8 wt % of nickel (II) oxide (NiO) and 4-6 wt % of copper (II) oxide (CuO). By the use of the welding flux for PH stainless steel, together with the tungsten inert gas welding (TIG welding) procedure, a weld bead with a weld D/W ratio greater than or equal to 0.8 can be formed between the two PH stainless steel workpieces. Therefore, the welding flux for PH stainless steel is suitable for single-pass, full penetration welding of the PH stainless steel workpiece with a thickness greater than or equal to 3 mm.
