• HSA800
• material characteristics
• welding properties
• homogeneity

In this research, 7 species of material characteristics test and 9 species of welding properties test for FCAW and SAW were proceeded to confirm the various material characteristics and welding properties of HSA800 developed recently. As a result of material test, HSA800 steel satisfied the KS and the criteria of homogeneity for the strength of the steel, confirmed as sound steel having excellent directivity and toughness. Test results of the FCAW and SAW partially satisfied the KS and the criteria of homogeneity for the strength of the steel, and confirmed as having a good weld zones. However, the result of SAW weld zone chemical composition test showed that the P composition is not satisfying the KS. According to the result of weld zone rod and plate tensile test results, the FCAW 1G appeared more better than the FCAW 3G, and the SAW PH2 appeared more better than the SAW PH1.
