Innovative developments in welding technologies and processes are required to achieve both greater productivity and enhanced quality of components manufactured by the welding industry. In India, through sustained efforts by researchers, academicians and technologists, significant progress has been made in understanding various arc welding processes, weldability testing, repair welding of power plant components, non-destructive evaluation of welds, consumable development, understanding microstructural evolution and correlating the microstructures with properties and performance of the welds. Developments in the science and technology of welding, across the globe, have reached a stage where welding processes based on scientific principles are being designed to tailor the composition, microstructure and properties for the requisite performance of the weld. India is in a unique position to accelerate focus on her research programmes to become leaders in developing newer welding processes and technologies. Major thrust is being given in research and development in the priority areas such as flux assisted GTAW, laser welding, friction stir welding, hybrid welding processes, intelligent welding and automation, development of NDE sensors, development of weld process models, development of techniques for measurement and analysis of residual stresses and control of distortion etc. The mantra for success in developments is through interdisciplinary collaboration among scientists and technologists working in the industry, academia, research centres and national laboratories. The focus and purpose are essential ingredients to be competitive and excellent in achieving results. The Indian experiences towards building robust technology based on sound scientific approach are discussed.
