Abstract
The Gas Tungsten Arc Welding (GTAW) process has always offered high quality weld deposits suitable for higher alloys with the low deposition rate. It is essential to have an automated welding machine in pump industries to increase productivity and quality which can also make the work easier for a welder. GTAW with hot wire for circumferential seam welding of motor body is a major development for pump industries which is required for good quality welding and mass production of the pump motor body. So it has been planned and designed a Special Purpose Welding Machine for Circumferential Seam Welding of Motor Body with respect to Lean Strategy & Human Ergonomics which will be a major challenge for all pump industries with latest technologies at low cost with respect to the current market scenario and also the customer requirements by analyzing and implementing their needs.
