Latest Advances in Welding Technology to Lower Cost in Automobile Sector

Automobile makers all over the world are continuously looking for new ways and technique to reduce manufacturing costs without scarifying built quality and automotive safety. To improve the performance of the car many companies are trying to reduce the weight of the car so that they can reduce the pollution which will reduce the environmental load substance and workability improvement to enhance the international competitiveness among the competitors. 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. To fully utilize such advanced steel products, the innovations of welding technologies are necessary and various welding technologies have been developed and applied with the progress of steel materials. This paper briefs about the developments and the actual applications of state-of-the-art in welding technologies.
