Comparación entre los métodos de Ultrasonido y Radiografía Industrial para la interpretación y evaluación de discontinuidades en juntas soldadas con bisel tipo V y proceso SMAW según norma AWS D1.1.

Abstract

In this paper the comparison between ultrasound and industrial X-ray nondestructive testing applied to butt welds with bevel type V and SMAW process, are described. This is accomplished from radiographic and ultrasonic pulse-echo type curves generated from standard specimens containing therein a characteristic discontinuity in each. The methodology applied is based on the AWS D1.1 standard. The work analyzes the results obtained with each method executed, allowing a comparison way for correlating the form of ultrasonic signal with the indications present on the radiographs. Thus, guiding the operator to establish what kind of discontinuity can be found by the two non-destructive testing. In addition, determining the advantages and limitations of each test applied.
