Comparison of Welding Distortions between TIG and MIG Welding Technique in Pipes

Abstract:

This paper presents a three dimensional thermo-mechanical analysis to investigate the effect of welding technique on welding deformations in pipe-pipe joints of SUS304 stainless steel type. Single-pass TIG and MIG welding with V-joint geometry in pipes having a diameter of 274 mm and a thickness of 6.2 mm is studied here. Two different welding techniques are analyzed. It has been shown that selecting a suitable welding technique can modify the amount of welding distortions in this pipe geometry.
