To apply force on to the weld spot area to form a strong joint the heat for joining the parts in resistance spot welding is an effect of the heat generated because of electrical resistance of welding circuits according to joule-lenz law (see fig1): where: international journal of latest trends in engineering and technology. In recent years, in order to minimize labor costs in high production manufacturing, industrial welding has become increasingly more automated, most notably with the use of robots in resistance spot welding (especially in the automotive industry ) and in arc welding in robot welding. The demand for new welding technology is also being driven, in large part, by the introduction of new materials to the industry — materials being used at times to reduce the overall weight of finished products, and lower product and production costs this trend is affecting a variety of sectors for example. Developments applicable to the offshore industry in the areas of advanced arc welding, friction stir welding and laser processes are described in each area, selected advances are reviewed and potential applications and benefits in offshore engineering are presented. Potential benefits and to classify them according to recent iiw metal transfer scheme the process control potential of other developments such as tandem and hybrid laser gmaw with also be described the trends in welding automation are reviewed and in understand some of the underlying technology and objectively. After analyzing recent trends in welding and manufacturing it becomes evident that the following must be considered with regard to the future of welding: with increased emphasis on welding as a basic manufacturing technology the growth rate in the future will approximate 8% per year and welding equipment shipments.
