Green Welding – The Saviour

Abstract

Though the welding technology has undergone a phenomenal change over the last five decades, the atmosphere or our environment is still under severe risk through the welding activities, including global warming. The main hazard due to welding activities are fumes and gases. In most of the welding operations, welding smoke is generated in large volume, which is a complex mixture of very fine particles (fumes) and airborne gases. To overcome the situation, green welding is the only way forward. Use of friction stir welding (FSW) is one of the ways towards green welding as well as to protect the environment somehow. Other less pollutant welding processes are also to be adopted as far as possible. Another way to protect our environment and to adopt green welding is to train the welders through virtual reality driven welding simulator.
