<p>To provide weld metal that has a high strength and toughness in the as-welded condition or in the annealed condition, the weld metal of the present invention contains by weight %, C:0.4-0.15%, Si:0.50% or less, Mn:1.0-1.9%, Ni:1.0-4.0%, Cr:0.10-1.0%, Mo:0.20-1.2%, Ti:0.010-0.060%, Al:0.030% or less, O:0.15-0.060%, N:0.010 or less, Fe and inevitable impurities as the remaining contents. The weld metal is further characterized by the fact that the ratio of Ti content (%) to Si content (%) i.e.,[compound type Ti]/[compound type Si] is more than 1.5 and the number A defined by the following formula is 0.50 or more, wherein A=[Ti]/([O]-1.1×[Al]+0.05×[Si]).</p> |
