Welding in Heavy Industries-An Indian Perspective

Heavy equipment manufacturers are continuously facing challenges to meet three most important project requirements - Quality, Cost&Delivery. Welding being one of the major operations in heavy engineering industries, welding technologists have to come up with new developments to cope up with these challenges. In order to counter these challenges, significant improvements are taking place in the field of welding and allied areas all over the world. Developments in materials are leading to complementary developments in welding consumable and process technology to weld these materials. Higher productivity processes are being implemented; existing processes are being fine-tuned to make them more efficient. Improvements in quality are being achieved by increased use of automation. Reliability of construction is ensured by the use of advanced NDT techniques. Similar developments are taking place in welding equipments and accessories to improve their efficiency. This paper presents an Indian perspective of developments that have taken place in welding and allied areas in heavy industries.
