Interpretation of the welding incompatibility in the T-joint with backing strip during ultrasonic test

Summary/Abstract: One of the most common methods for assessing the welded joints is a nondestructive method using ultrasonic waves. Despite the requirements posed to personnel engaged in research, practice shows that in many cases the incompatibilities in the butt welds in T-joint connections with backing strip are misinterpreted and consequently carry out to unnecessary and costly joints repair. The paper presents the results of tests carried out on samples without incompatibilities, for which the indications of defectoscope suggest the occurrence of apparent defect.
