Prueba Metalografíca en Uniones Soldadas con Presencia de Corrosión en Acero Estructural: Caso de Estudio Bicicleta

Abstract

In this Project, a test tuve of structural Steel from a bicycle frame was analyzed to study the behavior that causes corrosion in this type of material, which is welded by electric arc (electrode E6013) then, nondestructive was made such as analysis in the optical microscope and electron microscope; an scan was executed at different áreas of the specimen by taking pictures of various approaches to analyze its metallographic structure and types of corrosion. Also, a microhardness test was realized for a complete microstructural analysis of the material and identify the properties considering the environment that was used. Finally, a comparison of direct and indirect costs that can produce this attack on the element study was executed.
