Abstract
PURPOSE: To increase the bubbling effect of the covered electrode and elevate the blow-hole resistance, by especially limiting the combination amount of carbon source, Mo and Ni (alloy) in the coating agent composition of the electrode.
CONSTITUTION: The coating agent which contains Mg and CO3 of 8W27% in weight, one or both of TiO2 and ZrO2 of 14W35%, SiO2 of 5W30%, talc, mica, kaolin, china clay, sericite, etc. of 0.4W3.0% in all, carbon steel of alloy iron, etc. containing graphite, activated carbon or carbon of 0.14W0.85% in its total carbon amount, Mo, Ni or its alloy of 0.7W3.0% in Mo equivalent expressed by Mo+ 1/4.5Ni, is applied to the steel-cored wire by use of water glass. Resulting from the foregoing, Mn content in all the welding metals is made 0.10W0.35%. By use of the afore-mentioned coated electrode, the insufficient bubbling effect in case the diffusion hydrogen amount has been made less than 10ml can be compensated by utilizing reaction generated gas CO consisting of carbon and oxygen which are dissolving in the molten metal.
