The Latest Progress and Future Prospects of Welding Technologies Developed by Nippon Steel Corporation

New steel products, corresponding welding materials and welding process developed by Nippon Steel Corporation in recent years are introduced. For special properties of these materials used in the fields of shipbuilding, building construction, bridge construction, automobiles, home appliances, construction and industrial machinery, tanks and pressure vessels, pipelines and power equipment, Nippon Steel Corporation has also developed corresponding welding materials and welding technologies so that these steel products abovementioned can match well with newly developed welding materials and welding technologies and meet special requirements for all kinds of applications. And finally this paper points out that continuous developments on top quality steel products, new welding materials and welding technologies are increasingly important with the serious requirements for these properties of steel materials such as strength, toughness,fatigue property,corrosion resistance and heat resistance.
