Abstract

Resently, weight reduction of car bodies to reduce the environmental load substance and workability improvement to enhance the international competitiveness have made progress in the field of automotive materials. Under such circumstances, steel materials are required to have super high tensile strength and to be able to deal with complex structures of parts with high performance. In the field of thick plates and steel pipes, trend of mega-structural construction and high efficiency transportation leads to the strict demand of thick and high tensile strength steel products. To fully utilize such advanced steel products, the innovation of welding technologies are necessary and various welding technologies have been developed and applied with the progress of steel materials. This paper introduces the developments and the actual applications of state-of-the-art welding technologies in JFE Group.
