Comportamiento tribológico en las uniones soldadas, análisis del método de desgaste como medida de mejora a la seguridad estructural

Abstract

[ES] The study describes the process of analyzing the tribological behavior of welded joints, present in metallic structures and other structural elements affected by friction and wear, used in construction processes. Its control is of vital importance in ways to comply with the regulations regarding the structural code and on actions in the building that comply with the bearing capacity of the buildings. In the first part of the document, the concepts related to the science of tribology are briefly exposed. The elements that make up a tribological testing machine based on the ¿pin on disk¿ principle are described below. Finally, a practical case is presented as an example and experimental validation of the friction and wear analysis on the welded joint of cast metal sheets welded with a 60% Ni-Fe contribution electrode, finally the conclusions and the derived advantages are exposed from the application of the method to the control and execution of welded joints on site.
