The state of the art of weld seam radiographic testing: part 1, image processing
(AMER SOC NONDESTRUCTIVE TEST, 2007)
Over the past 30 years, a large amount of research has been conducted to develop an automatic (or semiautomatic) system for the radiographic detection and classification of discontinuities in continuous welds. There are ...
Detection and Classification of Weld Discontinuities in Radiographic Images (Part III: Unsupervised Learning - Phenomenological Analysis)
(AMER SOC NONDESTRUCTIVE TEST, 2008)
This is the third and final installment of a three-part article on detection and classification of discontinuities appearing in radiographic images of welds. The present installment is the continuation of the section on ...

Evaluation of Acoustic Emission Signal Parameters for Identifying the Propagation of Discontinuities in Pressurized Tubes
(AMER SOC NONDESTRUCTIVE TEST, 2008)
Acoustic emission tests are highly relevant among nondestructive tests applied to equipment in the petroleum industry. This paper presents methodologies for the classification of acoustic emission patterns obtained in ...
Effects of laser beam energy on the pulsed Nd:YAG laser welding of thin sheet corrosion resistant materials
(Trans Tech Publications Ltd, 2014-01-01)
The aim of this study was to value the possibility to join, for pulsed Nd:YAG laser welding, thin foils lap joints for sealing components in corrosive environment. Experimental investigations were carried out using a pulsed ...
