Over the last 30 years, there has been a large amount of research attempting to develop an automatic (or semiautomatic) system for the detection and classification of weld discontinuities in continuous welds examined by ...

This work proposes a new method for the automatic detection of the weld seam in radiographic images of pipeline welded joints. The proposed methodology is based on the optimization of parameters that are used to control ...

Electrochemical tests are well-established techniques used in corrosion studies, with the development of microcells and microcapillaries enabling localized evaluation of specific microregions of a welded joint. Until now, ...

Radiographic testing of weld joints is of great importance for verifying and maintaining weld quality. This work presents a new technique for the development Of an automatic or semiautomatic system for radiographic weld ...

The visual inspection of radiographic images of welds and pipelines is a very repetitive task, very hard for humans. However, using digital radiographic images, it is possible to develop computational tools to be applied ...

X-ray imaging has been developed not only for its use in medical imaging for human beings, but also for materials or objects, where the aim is to analyze (nondestructively) those inner parts that are undetectable to the ...

This work aimed to study the geometric and morphological characteristics of the weld bead obtained by MIG / MAG welding process using tubular wire 410 NiMo MC, with semi-automatic weaving and using pulsed current. The first ...
