摘要	PURPOSE:To execute gas welding which causes no strength drop of ductile cast iron by adding a mixture of powder of Mg, Ce, Si or a rare metal, and a slag making agent to a weld zone, and executing welding by use of a ductile cast iron rod. CONSTITUTION:When executing gas welding of ductile cast iron, the welding is executed by use of a ductile cast iron rod while adding a mixture of powder of a simple substance or an alloy of Mg, Ce, Si or rare metals, and a slag making agent to a weld zone. Or the welding is executed white adhering this mixture to the tip of the ductile cast iron rod. An atmosphere adjusting agent is added to this mixture as necessary. By this method, it is possible to execute gas welding of ductile cast iron which does not lose a nodular graphite structure, and accordingly, does not drop its strength.
