Simulación de juntas soldadas a tope por gtaw en placas planas de acero inoxidable AISI 430 mediante software ANSYS.

Abstract

In chapter 1 for the characterization of butt-welded joints by GTAW in flat plates of 3mm thickness of AISI 430 stainless steel, bibliographic information about butt-welded joints, information about ferritic stainless steels and their characteristics are compiled and reviewed. general studies, especially the steel AISI 430, also explains the weldability of ferritic stainless steels and the GTAW welding process, likewise information is acquired regarding the standardized mechanical tests that are carried out on steel specimens, the main tests made to the specimens are: tensile test, face bending test and root bending test, to finish chapter 1 it concludes with the information about how a macrography should be carried out because it is an important part of the process. of specimen characterization. In instruction to get the characteristics of the butt-welded joints of AISI 430 steel, the specimens of the welded material are subjected to a series of standardized destructive tests, in chapter 2 the process of preparing the specimens is explained, in this work They make up four AISI 430 stainless steel plates with dimensions of 300x125x3mm. These plates are welded using the GTAW welding process, thus obtaining two pairs of welded plates with dimensions of 300x250x3mm to subsequently obtain from them the standardized specimens that will be subjected to mechanical tests. To finish this work, standardized mechanical tests must be carried out on the previously obtained specimens. Chapter 3 details the process of the tensile tests, face bending and root bending, additionally a macrography is performed to obtain the Complete characterization of the samples made.
