We tested the quality of electroslag welds in which the 600mm dia hull steel casting was joined with hull steel forging. Electrode and flux used in the test were Kobe Steel US-40 electrode (3.2mm dia) and G-90 flux. Welds were very sound. No defects were found on weld metals, fusion line, and heat-affected zone. The static strength on the welds was never inferior to that of base metal. The rotary bending fatigue strength of fusion line was 19.9kg/(mm)^2 on the side of forged steel and 18.3kg/(mm)^2 on the side of cast steel, tensile strength ratio being 39.8% on forged steel side and 36.2% on cast steel side.
