Abstract

PURPOSE: To enhance the securing power of covering and improve dislodging resistance by specifying the ratio of SiO2 and alkali component in water glass at the time of securing the covering for welding materials such as coated electrodes by the water glass containing Na2O and K2O as alkali components.
CONSTITUTION: At the time of securing the covering for welding materials such as Ilmenite base coated electrodes by the water glass containing Na2O and K2O as alkali components, the SiO2: alkali components (molar ratio) in the water glass are made 1W1.9, preferably 1.5W1.8. Also, the solute concentration of the water glass (concentration of the water glass solid components in the final mixed state of welding materials) is 20% or more, preferably 20W50%. This method supresses the dislodging of the covering in the production and carrying processes of various kinds of coated electrodes and improves the yield at the production while enhancing their quality.
