Review of Selection of Tungsten Inert Gas Welding Parameters for Stainless Steel

Optimizing Welding Parameters for Stainless Steel using Tungsten Inert Gas Welding

Abstract

Tungsten Inert Gas (TIG) is also called as gas tungsten arc welding (GTAW). It is most commonly used welding process in many industrial applications. It uses non consumable electrode made of tungsten and shielding gas to prevent weld pool contaminations from atmospheric gases especially when joining high strength reactive metals such as stainless steel, aluminium and magnesium alloys. Stainless steel are the corrosion resistance steels which contains minimum of 10.5% of chromium. Although the nickel and molybdenum is added to improve corrosion resistance chromium is always the deciding factor. They have wide applications in chemical processing equipments, food equipments.
