  • the Mo content is less than 0.01% by mass, the tensile strength of the weld metal at the time of large heat input construction cannot be obtained sufficiently.
  • the Mo content exceeds 0.50% by mass, the weld metal becomes excessive in strength. Therefore, the Mo content is 0.01% by mass or more and 0.50% by mass or less per total mass of the wire.
  • it is 0.10 mass% or more and 0.30 mass% or less.
  • the total amount of Si and Si oxide in terms of Si is preferably 0.30% by mass or more from the viewpoint of obtaining a better bead shape and bead appearance. Moreover, the total of Si conversion amount of Si and Si oxide is preferably 1.40% by mass or less from the viewpoint of suppressing deterioration of the toughness of the weld metal.
  • Si 0.10% by mass to 1.00% by mass
  • Si improves welding workability by improving the viscosity of the weld metal and making the weld metal difficult to sag.
  • the Si content is less than 0.10% by mass, the viscosity of the weld metal is lowered, and the bead shape may be deteriorated.
  • the Si content exceeds 1.00% by mass, the austenite grains become coarse, which may cause deterioration of the toughness of the weld metal. Therefore, when prescribing the Si content, it is preferably 0.10% by mass or more and 1.00% by mass or less per the total mass of the wire.
  • Si 0.20 mass% or more is more preferable from a viewpoint made into a more favorable bead shape and bead appearance. Further, the Si content is more preferably 0.80% by mass or less from the viewpoint of suppressing deterioration of the toughness of the weld metal.
  • SiO 2 plays a role of supporting the weld metal as a slag forming agent.
  • SiO 2 content is less than 0.20% by mass, the amount of slag becomes insufficient and the bead may be drooped.
  • the content of SiO 2 exceeds 1.50% by mass, the deoxidizing power of the flux is lowered, and the toughness of the weld metal may be deteriorated. Therefore, when the content of SiO 2 is specified, the content is preferably 0.20% by mass or more and 1.50% by mass or less per total mass of the wire.
  • the content of SiO 2 from the viewpoint of a better bead shape and bead appearance, and more preferably at least 0.40 mass%. Further, the content of SiO 2 is more preferably 1.30% by mass or less from the viewpoint of suppressing deterioration of the mechanical properties of the weld metal.
  • ZrO 2 plays the role of supporting the weld metal as a slag forming agent, like SiO 2 .
  • the slag melting point becomes low, the bead has a drooping shape, and a good bead appearance cannot be secured.
  • the content of ZrO 2 exceeds 1.0% by mass, the slag melting point becomes too high and a bead shape such as a convex shape is obtained, and a good bead appearance cannot be secured.

  • the total amount of B and B-converted B exceeds 0.0300% by mass, the strength of the weld metal is remarkably increased and the toughness is lowered. Therefore, the total of B and B oxide in terms of B is 0.0003 mass% or more and 0.0300 mass% or less per total mass of the wire. In addition, it is possible to contain only B oxide.
  • Mg and MgO are components that may be contained as impurities from natural raw materials such as titanium oxide.
  • the Mg content is 0.10% by mass or more, the amount of spatter generated increases, and the moisture absorption resistance of the wire deteriorates by forming a compound with Na. Further, if the content of MgO is 0.10% by mass or more, the bead becomes convex and the appearance of the bead is deteriorated due to an increase in the slag viscosity. Hygroscopicity deteriorates. Accordingly, the Mg content is less than 0.10% by mass and may be 0% by mass with respect to the total mass of the wire. Further, the content of MgO is less than 0.10% by mass and may be 0% by mass with respect to the total mass of the wire.
  • Total of Na conversion amount of Na compound other than NaF and K conversion amount of K compound 0.20 mass% or less
  • Na and K have an effect of stabilizing the droplet transfer of the arc during welding, but this effect is borne by NaF.
  • excessive addition of Na and K deteriorates the moisture absorption resistance of the wire.
  • the total amount of Na compound other than NaF and Na compound of K compound exceeds 0.20% by mass, the moisture absorption resistance of the wire deteriorates and the diffusible hydrogen of the weld metal The amount increases. Therefore, the total of the Na equivalent amount of Na compounds other than NaF and the K equivalent amount of K compound is 0.20 mass% or less per the total mass of the wire.
  • Na conversion amount in Na compounds other than NaF, and K conversion amount in K compound either 0 mass% may be sufficient and both may be 0 mass%.
  • F conversion amount of F compound other than NaF 0.10% by mass or less
  • F exists as a fluorine compound in the flux and has the effect of reducing the hydrogen partial pressure in the welding atmosphere and reducing the amount of diffusible hydrogen in the weld metal. This effect is borne by NaF.
  • excessive addition of F increases the amount of fumes generated during welding. Specifically, when the F equivalent amount of the F compound other than NaF exceeds 0.10% by mass, not only the fume generation amount increases, but also the spatter generation amount increases and the arc stability deteriorates. Accordingly, the F equivalent amount of the F compound other than NaF is 0.10% by mass or less per wire total mass, and may be 0% by mass.

  • Bead appearance With regard to the bead appearance, welding was performed in two postures of horizontal fillet and vertical improvement under the three types of welding conditions [1] to [3] shown in Table 4, that is, a total of six types of welding. After carrying out the welding test, each formed weld was observed and visually evaluated. Specifically, “ ⁇ ” indicates that the weld appearance of all the welds obtained in the six types of welding tests was not wavy and good for each welded part obtained in the six types of welding tests. Any one of the beads with a bead appearance having a wave-like appearance was evaluated as “x”.
