Some Recent Innovations in TIG Process

Abstract

The use of greater plate thicknesses in the new aerospace and hydrospace materials has increased the need for new, high speed, high quality welding processes. Conventional methods to weld these materials have serious economic limitations because of low speed. Recent developments, such as plasma arc and electron beam are being utilised to some extent, but conventional tungsten inert gas welding remains the most widely used process where weld quality is very important. Within the last decade, many refinements have been made to increase the speed of welding with TIG process, the most important one being its automation.
