JP-A-58-6795 and JP-A-58-132
Although it is shown in Publication No. 393, in both cases pure Ni is used in the outer skin.
There are no known ones that use Inconel alloy for the outer skin.

大きな手間を要する。MIG welding with solid wire produces a hard oxide film on the surface of the bead, and when welding in piles, the oxide film gets rolled up, causing blowholes, poor fusion, weld cracks, etc. For this purpose, it is necessary to remove the oxide film, which requires a great deal of effort.

る。Furthermore, since Inconel alloy has poor thermal conductivity compared to mild steel, it is used only for downward welding and is not suitable for vertical or horizontal welding. TIG welding and shielded arc welding, which are suitable for vertical and horizontal welding, are inefficient, and especially in the case of shielded arc welding, the quality of the weld varies widely depending on the skill level of the welder. The flux-cored wire disclosed in JP-A-58-6795 is for submerged arc welding, requires an additional 7 lux for submerged arc welding, and is designed for downward welding only. Also, JP-A-58
The 7-lux-cored wire of Publication No. 132393 is also for downward welding, and since the outer sheath is Ni, for example, the welding start part melts first from the outer sheath, so the alloying elements in the flux solidify before they are sufficiently melted. The object of the present invention is to provide a flux-cored wire for Inconel alloy welding that allows for efficient welding in both horizontal and vertical positions and provides a uniform and sound weld. shall be.

Moreover, if it exceeds 30 inches, there will be too much slag, causing problems such as covering the molten pool, and causing defects such as poor fusion and slag entrainment.

~7% is used, but these improve the fluidity of the slag and improve the compatibility between the weld metal and the base metal, resulting in a good bead shape. In addition, during welding within a groove, it prevents slag from covering the molten pool and makes the slag brittle so that it can be easily removed. Furthermore, the carbon tR gas decomposed by the welding heat blocks the atmosphere, prevents oxidation of the weld metal and the generation of blowholes, and also protects the weld metal as a slag forming agent. 0,
If it is less than 2%, no effect can be expected, and if it exceeds 7%, not only will spatter occur frequently, but also carbon in the weld metal will increase, deteriorating corrosion resistance and toughness. As the carbonate, for example, LizCOs + Bacon + CaC0m

These fluorides are used at a rate of 5 to 2%, but during welding, these fluorides decompose due to welding heat during the process of wire droplets transferring to the molten pool, generating fluorine-based gas, and shielding the area near the transferring droplets and molten pool. This prevents blowholes and cracks in the weld metal. If the ratio is less than 0.05, the effect cannot be expected;
If the temperature exceeds the limit, spatter and fluorine-based gas will increase, worsening welding workability. Examples of fluorides include CaF2+

Metal powders other than Ti and At are generally used to supplement oxidation consumption during welding or to add alloying elements from flux. If the total amount of metal powder is less than 1%, there will be insufficient replenishment for the oxidative consumption of alloying elements, and if it exceeds 7%, the balance with flux raw materials other than metal powder will be poor, resulting in poor welding workability.
