Health Appraisal of Gas Shielded Metal Arc Welding

Abstract

Gas shielded metal Arc welding had established its persence in • fabricating Industries over many other processes due to its advantages of higher productivities, less cost of welding and ultimately zero defect welding with less dependent on the welders skill. An increasing trend is being observed through out the world in switching over to GMA welding wherever possible from conventional welding. Added to this, the free availabilities of different kinds of Gas mixtures, mainly Argon based mixed Gases and various types of Flux cored wire had increased the process capabilities to suit almost every application that we can think off. Indian Welding Industry has also started adopting GMAW process more and more in order to take the advantages of availabilities related to Inverter based power packages, various Gas mixtures and solid/Flux cored wires of various composition etc.
