Abstract (English):	Failures in welded joints constitute a challenge that requires a scientific approach due to its phenomenological essence. This work determines the causes of failure in welded joints of a piping system, which were carried out with the SMAW process. Visual inspection, tension tests of the base material, chemical analysis by optical emission spectrometry as well as macrograph and metallography of the welded joint were carried out to a sample extracted from the damaged area using a cooled disc. In conclusion, we can say that the cause of failure has its origin in the poor procedure applied when welding, although other factors such as mechanical fatigue or an inappropriate design could also have been present.

Abstract (Spanish):	Las fallas en las uniones soldadas constituyen un desafío que requiere un enfoque científico por su esencia fenomenológica. En el presente trabajo se determinaron las causas de falla en uniones soldadas ocurridas en los soportes de un sistema de tuberías, las cuales fueron realizadas con el proceso SMAW. De la zona siniestrada se extrajo una muestra usando disco refrigerado a la que se le realizó inspección visual, análisis químico por espectrometría de emisión óptica, ensayos de tensión del material base, además de macrografía y metalografía de la unión soldadas. Se concluye que la causa de falla tiene su origen en el deficiente procedimiento aplicado en la ejecución de la soldadura, aunque también pudieron estar presentes otros factores como la fatiga mecánica y un diseño inapropiado.
