COMPARISON OF RESIDUAL STRESSES BETWEEN TIG AND MIG WELDING TECHNIQUE IN PIPES

摘要：

This paper presents a three dimensional thermoelasto-plastic analysis,using finite element techniques,to analyze the thermo mechanical behavior and evaluate the residual stresses in pipe-pipe joints of AIS1 stainless steel type.Single-pass TIG and MIG welding 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 residual stresses in this pipe geometry.
