Weld metal and welded structure having weld joints using the same

A weld metal, comprising Fe, and, by weight %:

• C:
• 0.04 to 0.15%;
• Si:
• 0.50% or less, not including 0%;
• Mn:
• 1.0 to 1.8%;
• Ni:
• 1.0 to 4.0%;
• Cr:
• 0.10 to 1.0%;
• Mo:
• 0.20 to 1.2%;
• Ti:
• 0.010 to 0.060%;
• Al:
• 0.030% or less, not including 0%;
• O:
• 0.015 to 0.060%;
• and
• N:
• 0.005 to 0.010%;
• wherein,
• a mass ratio of [compound Ti]/[compound Si] is more than 1.5, wherein the ratio reflects the amount of Ti oxides present to the amount of Si oxides present obtained by electrolytic extraction,
• a number A is 0.50 or more, and satisfies:
• A=[Ti]/([O]−1.1×[Al]+0.05×[Si]),
• wherein [Ti], [O], [Al], and [Si] are a content of each element by weight %, and
• an average size of carbide particles with a circle equivalent diameter of 200 nm or more in the weld metal is 350 nm or less.
