Abstract
PURPOSE: To achieve more difficult hygroscopicity and lower hydrogenation while suppressing the production amount of welding hume by using te water glass whose solute concentration is specified at the time of securing the covering for welding materials such as coated electrodes with the water glass containing Na2O and K2O as alkali components.
CONSTITUTION: The water glass whose solute concentration (concentration of water glass solid components in the final mixed state of welding materials) is 10W 32%, preferably 15W30% is used 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 1W1.9, preferably 1.5W1.8. With this method, the improvement in welding workability and the maintenance of working environments are achieved. Further, the reduction in the residual water glass component amount which becomes hydroscopic source and the reduction in the residual silanol group amount which becomes hydrogen source are made possible.
