Abstract

PURPOSE: The covered arc welding rod with which the amount of occurrence of the welding smoke is suppressed by using the coating meterial containing the limited amount of Fe, siO2, TiO2, Al2O3, iron oxide, MgO, CaO and/or BaO, organic matter, alkali metal oxide, Mn and moisture.
CONSTITUTION: The coating material containing, converted in terms of each element and substance, Fe: 30W60%, SiO2: 20W35%, TiO2: 5W15%, Al2O3: 1W8%, iron oxide: 1W6%, MgO: less than 8%, one or both of CaO and BaO: 1W10%, organic mattee: 0.2W2%, alkali metal oxide: 1W5%, Mn: 4W11%, etc. and containing hydrated mineral such as montmoril lonite, etc. of an amount corresonding to 0.3W1.5% as water content, is applied to the steel core rod. When this covered arc welding rod of high content of iron powder is used, the emission of smoke due to welding can be reduced sharply without giving adverse influences to the working efficiency of welding, the capacity or appearance of the joint
