Abstract |
|
Tungsten inert gas welding process is mainly used in industries mainly for high quality and good appearance. Low depth of penetration (DOP) is achieved during single pass. To achieve required high DOP, speed of welding should be reduced thus productivity reduces significantly. To overcome this disadvantage, Activated Tungsten Inert Gas (A-TIG) Welding is found. In this method flux is coated over the surface of the joint before welding which increases the depth of penetration and reducing weld bead width by two mechanisms marangoni convection and arc constriction. This paper represents a review on ATIG welding process and its mechanism. |
