Rooting for Environment Friendly Arc Welding Process in India

Abstract

India needs large energy along with large increase in demand for its present arc welding load. Energy coupling between resource and joint in arc welding is loose. One reason is that fuel to joint preparation involves dual conversion. Each energy conversion phase incurs large losses. Poor conversion at load end is critical for cascading process as loss makes large impact on passive grid. Loosely coupled energy network depletes resources and pollute environment faster. Its optimization in arc welding is complex as it has multiple and diverse loss centers at load end. Concrete understanding of loss centers always looks for efficient method and energy delivery mechanism to achieve simultaneously energy efficiency, process efficiency, productivity with weld quality, and maintain local and global environment - for our working and living. High frequency power electronics equipments, as if, re-discover ‘the subject of arc welding process’ to generate total solution. Performance, energy efficiency, reliability, compactness, better economics and reduction of life cycle cost etc are inherent features modern equipments offer. Evolution in arc welding equipments has successfully met the characteristics of optimum weld gap dynamics to reduce process diversity and simplified process learning. The concept ‘Green’ makes such process perfectly optimized to create a balance between energy use and environment we live in. This article details the procedure for finding efficient equipment controlling arc welding process using compatible and efficient method to achieve quality, energy and process efficiency and also minimize its impact on environment.
