Abstract
PURPOSE: To develop an electrode of superior welding workability and joint performance by constituting the coating material of a low hydrogen type coated electrode for fillet welding with specific composition components and setting the bulk density of the coating material after baking in a specific range.
CONSTITUTION: A coating material having the following composition is coated on the outside circumference of a core made of mild steel and is baked as a low hydrogen type coated electrode for fillet welding. The composition of the coating material is 10W20% SiO2, 5W20% TiO2, 15W45% iron powder, 5W30% carbonate (where the total of carbonate such as CaCO3, BaCO3, etc. other than MgCO3 is kept ≤10%), 3W15% metal fluoride, 3W15% deoxidizing metal such as Si, Mn, etc. or further <15% MgO or <5% Al2O3 and <5% powder of Cu, Mo, Ni, Cr alone or their iron alloy are contained. The bulk density of the coating material after baking is controlled to 2.3W3.3g/cm3.
