The modern welding technology hue more then 100 years history, and during that period, the welding has been playing an important role in the development of the manufacturing processes/systems as a key technology. In the time we enter the 21st century, it is question how to develop the innovative and attractive welding technology, in particular by the younger generation. The present report discussed the future trend of welding engineering mainly in Japan after reviewing the previous growth of welding engineering.

The research trend in the corrosion behaviour of stainless steel weldment has been reviewed. The welding technology plays an important role in the fabrication of structure such as chemical plant, power plant, because welding can influence various factors in the performance of plant and equipment. This has led to an increasing attention towards the corrosion behaviour of weldment which has been one of the major issues for both welding and corrosion research engineers. The aim of this paper is to give a short survey of the recent technical trends of welding and corrosion including the electrochemical corrosion, stress corrosion cracking, and corrosion fatigue in connection with the welding materials, welding process, and welding fabrication. This study covers the corrosion behaviour of stainless steel weldment collected from the COMPENDEX DB analysis of published papers, research subject and research institutes.

Increase of combat capability through the lightweighting of vehicles has been internationally issued. One of the methods for lightening is applying high hardness armor(HHA) steel which is outstanding ballistic performance and protection performance compared to weight. Development of HHA steel is currently completed in America, United Kingdom, Australia and Germany. It is used for not only combat vehicle, but also various combat device. Korea is developing new material of HHA steel according to this trend. When such HHA steel is applied to structure, welding process is used for connection of the structure. Cracks from hydrogen embrittlement and cold cracking are easily generated in welds of HHA steel and it greatly affects the strength of all structure. Decrease of strength from welding defect is critical to combat capability. Therefore, welding process optimization is important for performing the role of structure. In this study, international welding technology is reviewed through scientific research paper and patent.

The trend of the fabrication technology of high strength, high toughness aluminum alloys by the severe plastic deformation(SPD) process and the welding technology of lightweight alloys in the automobile has been studied. The lightweight aluminum alloys can reduce vehicle weight, while stringently demanding the high quality and efficient welding techniques, to produce the best weldments. Among the production technologies, welding plays an important role in the fabrication of lightweight vehicle structure. This paper covers the scientometric analysis of the severe plastic deformations of lightweight alloys and the welding technology in the automobile which are based on the published research works in the 'HPT, ECAP and rolling', and 'welding technology of the automobile' obtained from Web of Science, and deals with the details of the background data of the HPT, ECAP, and rolling of lightweight alloys, and welding technology of the automobile technology.

In recent days, welding technology developed in various field of industry, a ship, a building, a structure, a high pressure vessel ect. A welding structure should be base on a safety Welding engineers and welding technicians have a problem in acquiring welding technology, because young people avoid state of the art, beginning their careers In this field. The optimum welding state depends upon the most welding condition, mechanical properties of the base metal, welding processes and arc stability. Base on these fact, the suitable parameters of welding condition can be found through various welding experiments. Therefore, it Is very Important for welding professional engineers to take an active role In advancing new welding technology
