Latest Patents

One of his latest patents is the "Process for production of a low hydrogen type covered arc-electrode." This invention focuses on minimizing the sources of diffusible hydrogen in the electrodes by carefully selecting the ingredients used in their production or by baking these ingredients. The process involves baking the covered arc-electrode at high temperatures to significantly reduce the amount of diffusible hydrogen in the weld metal while preventing the decomposition of limestone, a key covering component, through a novel baking atmosphere containing CO₂. Additionally, the weight ratio of Na₂O/K₂O in the covering is adjusted to be 1 or more to control the amount of fumes produced.

Another significant patent is the "Non-fused flux composition for submerged-arc welding." This composition is particularly suitable for horizontal submerged-arc welding in the production of welded structures such as storage tanks and pressure vessels. It comprises a specific blend of materials, including 13 to 30% TiO₂, 5 to 50% CaF₂, 20 to 40% MgO, 12 to 30% Al₂O₃, and others, which provide excellent low-temperature fracture toughness of the weld metal.
