| Synopsis: The trends of the welding technologies and research developments in recent 10 years are outlined by including changes in social conditions and requirements of the market. Welding materials and a process were developed for high efficiency and high quality welding, e.g., a low spattering solid wire for CO2 arc welding, a high efficiency one pass submerged arc welding process using super-high heat input for heavy section steel plates, and a flux cored wire with excellent pitting resistance for primer coated steel plates. In viewpoint of the weldability of steel materials, new welding technologies were established for surface coated steel sheets and high tensile strength steel plates. |
