Abstract

PURPOSE: To provide an electrode giving weld metal of less segregation and high quality by making the grain size constitution of metallic powder and alloy powder as well as other raw materials for coating material in coated electrodes adequate.
CONSTITUTION: The essential components used for the coating material of coated electrodes containing low hydrogen are 25W55% in total carbonates of ≥1 kinds selected from the group consisting of CaCO3, MgCO3 and BaCO3, 2W30% CaF2 and ≤15% metallic powder and/or alloy powder as well as a binder. With this coating material, the grain sizes of the raw materials except the metallic powder and/or alloy powder are regulated at ≤296μ, further the ratio of grain size ≤74 is regulated to ≤25%, and the grain sizes of the metallic powder and/or alloy powder of ≥149μ grain sizes are regulated to ≤20%.
