Estudio del proceso de soldadura GTAW para ceros inoxidables y aluminio.

Abstract

The objective of the present work is to establish an appropriate guide of the electrical and functional parameters for the application of electric arc welding with a tungsten electrode and gas protection, which is carried out through the development of a descriptive methodology, the same that facilitates the adequate obtaining of these parameters, which influence the mechanical properties of the materials, as well as the quality of the welding bead.The present research work shows the study of the GTAW process applied in carbon steels, stainless steels and its ferrous alloys, this information is carried out through the compilation of relevant information, where it is structured in an orderly and precise manner, describing each of the welding parameters (GTAW).At the same time, the correct use and parameters are described. operations, all this depending on factors such as torch handling, joint design, choice of electrode where s e is involved the power supplied through the welding machine, welding speed, as well as the shape of the tip of this when applied to the study materials. Due to the different microstructure that the materials to study have, the operating parameters are specified individually, which have operating information according to the material, amperage, arc voltage, flow rate, etc., main parameters to carry out in welding manual and automatic in the GTAW welding process. All the information is gathered and structured in an orderly manner in tables, in which the different operating parameters of the materials already described can be distinguished, this being the main objective of this study, in such a way that clean joints are obtained. and with excellent mechanical properties.
