A Review on Welding Characteristics of Ferritic Stainless Steels and Effects of Various Weld Process Parameters

Today is the world of stiff and cut-throat competitiveness among the manufacturing industries. The objective of every industry is to produce better quality products at minimum cost and increase productivity. Welding is a process where the coalescence of two metals is achieved by the application of heat and/or pressure with or without filler metal. This is the only technique for developing the monolithic structure. Welding defects can cause practical problems if not solved. The TIG welding is also called Gas Tungsten Arc Welding (GTAW), which uses a non-consumable tungsten electrode to produce the weld. TIG welding is used to produce high-quality welds and is popular among welding processes. Its productivity depends upon many factors like arc voltage, shielding gas, weld speed, and heat generated during the welding process. This paper is an attempt to present a review about the welding of ferritic stainless steel between AISI 410S and AISI 430 by the TIG welding process.
