Inventor: YAMAGUCHI TADAMASA
IPC: B23K35/40
Filed: 1989-12-22
Abstract: PURPOSE:To greatly reduce the welding defects by compounding and mixing flux raw materials for welding, then pressurizing and melting the mixture in a melting furnace pressurized to a specific pressure, tapping the melt to the atm., solidifying and cooling the melt, and then grinding and sizing the material. CONSTITUTION:Gases, such as hydrogen, nitrogen and oxygen, are dissolved in the molten flux for submerged arc welding. The flux is pressurized and melted in order to increase the dissolving amt. of the gases and the melt is cast in the atm. of the pressure lower than the pressure of the dissolving atmosphere, by which the dissolved gases are expanded and the flux is foamed. The flux is formed by compounding and mixing the flux raw materials for welding and pressurizing and melting the mixture in a melting furnace pressurized to 800 to 1,000Torr, then tapping the melt into the atm., solidifying and cooling the melt, then grinding and sizing the material. The fused type foamed flux for submerged arc welding which is small in bulk density and can greatly reduce the welding defects is produced in this way.
