Evaluación de defectos y discontinuidades de la soldadura por medio de la aplicación de ensayos no destructivos en la fabricación de tuberías de 3000 mm de diametro

Abstract

The development of this research was carried out to identify the different discontinuities found by the application non-destructive methods of examination on the welding cords to a pressure pipe ASTM A572 Gr. 50 material manufactured in a metalworking industry in the city of Guayaquil. This research proposes solutions to reduce the different types of discontinuities by conducting an analysis of the causes either by technological factors or human factors. During the process, a comparative analysis of costs per meter application non-destructive methods of examination among five companies that provide their service in the city of Guayaquil was carried out. It is concluded that the presence of discontinuities is due to the human factor since these include causes such as poor application of welding techniques and improper handling of welding equipment. This project makes recommendations to reduce the presence of discontinuities in the welding cords and improve the quality of the finished product reducing costs for repair and minimizing delays in production.
