In this paper, the mechanical properties such as the toughness and the strength of the submerged arc weld (SAW) metal are investigated. Main target is the fillet weld metal by one pass SAW used for the built-up H-shaped beam. For comparison, the JIS deposited metal is also prepared. Charpy absorbed energy vE0 of the JIS deposited metal was higher than the specified value of JIS. On the other hand, vE0 of the fillet weld metal was lower than the JIS deposited metal, and some of the fillet weld metal was lower than the specified value of JIS.
