Several kinds of low-alloyed-steel electrodes were manufactured for trial. Good welds, with sufficient strength and ductility, joining two plates consisted of 60 kg/mm2-high-tensile steel were made by CO2-O2-arc welding with those electrodes. For example, strength of all weld metal ranges from 61 to 68 kg/mm2 elongation almost from 22 to 28% and impact value at -40°C from 3.6 to 5.4kg-m/cm2. All joint-tensile-test specimens were broken at base metal. And the results of side bend test for welded joint were recognized to be satisfactory.
