Though the studies about the consumptions of coated electrodes in welding arc have been made by many researchers, their results are still not enough to analyze the phenomena of consumptions. It is author's aim to investigate the influences of coating materials upon the melting-characteristics of electrodes in arc. Some experiments have been performed about the following kinds of coating materials ; a ) H_3BO_3, Al_2O_3, BaCO_3, CaCO_3, and other uni-component coating materials, b) Illmenite, cellulose, Titanium, low hydrogen, high hematite type, and all of that which include Fe-Mn. c ) Model electrodes. The results are summarized as follows; a ) The melting-characteristics of cathode are much influenced by the kinds of coating materials, while those of anode are not. b ) The introduction of Fe-Mn into coatings acts to increase the melting-rate of cathode, c ) Generally speaking, a oxydizing agent invites the decrease of melting-rate of cathode and a reducing agent does the increase of it.
