Continuing from Report 1, this report deals with the effect of metallurgical structure of single and multiple pass deposited metal in submerged and CO2 gas arc welding on the notch-tough ness of deposited metal in automatic arc welding. It was found that when deoxidization of deposited metal was satisfactory, the effect of grained refining of metallurgical structure was exhibited and was extremely effective for improvement of notch-toughness of deposited metal.
