The authors prepared low-carbon steel filler wires of various manganese and silicon contents on trial, and performed experiments on oxy-acetylene gas welding using them. In this case, mild steel plates of different thickness were butt-welded by weaving and backhand techniques. Next, mechanical properties of deposited steels were measured and bend tests of welded joint were also performed. Then the authors investigated effects of chemical composition and surface-condition of welding rod on mechanical properties of deposited steels. The steel rods containing proper amounts of manganese and silicon were excellent as gas welding rods for steel. The low carbon steel rods containing 1.3-1.5% Mn an 0.1-0.3% Si are suitable for gas welding of mild steel. And the suitable contents of manganese and silicon appear to be 1.6-1.8% Mn and 0.1-0.3% Si respectively for the gas welding rods of high tensile steels.
