摘要： PURPOSE:To improve welding efficiency and bead shape by controlling the contents of C in the entire wire, and the iron powder, Mn+Si, Al, etc., in a flux respectively to specific wt%, and setting a flux filling rate to prescribed %. CONSTITUTION:The content of C in the entire wire is specified to 0.01-0.06% by wt%, and the content of the iron powder in the flux is limited to 65-85%, Mn+Si to 13-23% and Mn/Si to 1.5-3.3. The content of Al in the flux is limited to 1-3% and Na+K to 0.05-0.2%. The content of a slag forming agent is controlled to 0.5-6.5% and the flux filling rate to a 13-25% rang. The C, alkali component and flux filling rate are controlled by the above- mentioend method, by which the generation of spatters is decreased. The contents, ratios, etc., of the Mn, Si and Al components contribute to the improvement in the based shape. The welding efficiency is, therefore, improved and the based shape is improved.

摘要： PURPOSE:To obtain stable droplet transfer form in a wire containing metal powder flux, by providing an electrically insulated layer at the boundary between covering metal and flux and thereby making welding current flow only in the covering metal. CONSTITUTION:An insulating layer 2 is formed on the surface (the side that becomes inner face of the hole when curved) of covering metal 1, and the hole is filled with flux F while bending the covering metal 1, and a wire containing flux F is obtained. When welding is made by using this wire, droplet transfer becomes smooth and spatter becomes hard to occur.

摘要： 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 1-1.9, preferably 1.5-1.8. 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 20-50%. 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.
