    Análisis de soldabilidad del acero HSLA ASTM A1011 GR 50 y su incidencia en la fabricación de carrocerías metálicas para buses
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Mecánica Mención Diseño, 2019) Poveda Almeida, Welligton Vladimir; Yunapanta Velastegui, José Luis
    This investigation carried out, based on the large number of companies that manufacture metal buses bodies, which exist in Ecuador, use welding as the main process, these performed the weldability analysis between the ASTM A500 Gr C steel and the HSLA ASTM A1011 Gr 50, to investigate their weldment behaviour of a section of the body structure, in which the type of joint, parameters and welding processes to be used were analyzed. In addition, his work was based in a bibliographic way, where several documents were found with which it was possible to base this research in a profound way, at the same time, chemical, mechanical and physical tests were carried out with the cooperation of the company VARMA S.A., with the laboratories of the Faculty of Mechanical Engineering of the Technical University of Ambato, the laboratories of the Salesian Polytechnic University and the Center for the Development of Carrocero Metallechanical Productivity, as well as every invaluable technical staff and human talent from each area, to determine the properties of each material by carrying out tests such as: penetrating liquids, metallography, hardness, tensile strength and impact, to finally compare the results and identify the incidence of each one on the manufacture of bodies. Finally, some mechanical properties of HSLA ASTM A1011 Gr 50 steel were obtained, which outperformed ASTM A500 Gr C steel, thus concluding that these results contribute to both business and country development.
