En la presente investigación se realizó un análisis de la resistencia a la fatiga en las juntas soldadas de las tuberías para aire presurizado utilizadas en minería. Para su obtención se inició por la obtención de los parámetros de soldeo los cuales se realizaron según la norma AWS A5.1 y API1104. Con dichos parámetros se realizó un análisis por elementos finitos a través del software Autodesk Nastran 2023 con el que se pudo obtener los esfuerzos de Von Misses y los factores de seguridad en la junta soldadas donde se visualiza un decremento de 4 en los factores de seguridad de la zona afectada por el calor con respecto al metal base alejado del cordón. Después se realizó una gráfica del esfuerzo y los factores de seguridad en cada punto para con ellos calcular la resistencia a la fatiga con un valor de 115 Mpa. Finalmente se realizaron los ensayos de laboratorio para co...

The objective of this research is to determine whether a photovoltaic system is more beneficial than a traditional electrical grid system for households with high energy consumption in the district of Paiján. It was considered a quantitative approach, applied type, non-experimental - transversal design and descriptive scope given that a comparison was made between the two variables to know the differences between both groups. It was carried out in a house with the installation of a photovoltaic system, making use of observation and documentary analysis techniques. The result of the research was that the photovoltaic system is more beneficial in terms of photovoltaic generation and traditional electricity distribution variables because it contributes to environmental protection, it is also a technology that is growing rapidly and does not generate maintenance and consumption costs, excep...
