Abstract

In the field of mechanical manufacturing and construction engineering, welding is a fundamental joining process that enables the fabrication of structures and components for a wide range of applications. Among the numerous welding techniques, the Tungsten Inert Gas (TIG) welding process stands out due to its ability to produce high-quality and precise welds, particularly when welding stainless steels. Stainless steel is widely used in industries such as automotive, aerospace, petrochemical, and food processing because of its excellent strength, corrosion resistance, and versatility. This study investigates welded specimens made of AISI 304 stainless steel produced using different welding processes: TIG (Tungsten Inert Gas), TAG (Tungsten Active Gas), and ATIG (Activated Tungsten Inert Gas). The aim of the study is to evaluate the influence of different welding processes and varying heat input levels on the dimensions and geometrical characteristics of the welded joint.
