Simulation on temperature fields and phase transformation of 316L stainless steel tubes during Orbital – TIG auto welding process

Abstract

Orbital - TIG (OT) auto welding process was applied for the weld connection of the fixed pipe lines. The heat distribution of the OT welding has influenced phase transformation and quality of the weld. In this paper, the temperature fields and phase transformation of 316L stainless steel pipes have been simulated during OT auto welding process. The numerical simulation has been used and supported by the JMATPRO 7.0 and SYSWELD softwares.
