Soldadura T.I.G de acero inoxidable. Modelo numérico para el cálculo de temperaturas en la Z.A.T. | [T.I.G. welding of stainless steel. Numerical modelliñgfor temperatures calculation, in the HAZ]

Abstract

In this work, a numerical method for calculating the temperature field into the heat affected zone for butt welded joints is presented. The method has been developed for sheet welding and takes into account a bidimensional heat flow. It has built a computer program by MS-Excel books and Visual Basic for Applications (VBA). The model has been applied to the TIG process of AISI 304 stainless steel 2mm thickness sheet. The welding process has been considered without input material. The numerical method may be used to help the designers to predict the temperature distribution in welded joints.
