Shaft Inspection Using Phased-Array Compared to Other Techniques
27th November 2019
Technical Paper
The main purpose of this article is to suggest a new multi-orientated Phased Array (PA) inspection, which could reduce the cleaning and disassembly of shaft assembly in general.
The main idea is to replace the conventional surface technique inspection by an encoded circumferential PA inspection using the Curved Surface Correction (PA CSC) of the Veo+. This inspection, combined with a PA inspection at the extremity of a shaft would cover all the possible flaw orientation and hopefully increase the probability of detection, the interpretation capability and productivity.
Phased Array Techniques and Defect Evaluation for Composites
8th November 2019
Composite materials are well known for their stiffness, corrosion resistance and low density and they come in all different geometries. Theses composite complex shapes along with their anisotropy, makes UT inspection more challenging than inspections for conventional materials like steel.
This scientific paper will address general issues of composites relating to geometry, attenuation and assessment methods.
Inspection of a Welded T-joint
2nd September 2019
The main types of T-joint welds are inspected with conventional UT, where common defects are generally cracks and lack of fusion. Having a better understanding of the defects can certainly help the technicians become more alert, especially when considering the main problematic areas.

Improving resistance properties in composite is all about improving stress and strain resistance such as ultimate tensile strength.
Ultrasonic NDT Corrosion Mapping From Phased Array to FMC-TFM
2nd August 2018
Corrosion inspections are used to evaluate the remaining wall thickness or the presence of mid-wall anomalies in pipeworks, pressure vessels, and other metallic structures.
FMC/TFM Technique for Defect Characterisation
2nd August 2018
Defect characterisation has always been a challenge for ultrasonic inspection techniques.
Hydrogen Blister Progression FMC/TFM Assessment
2nd August 2018
Hydrogen blistering usually occurs in systems where oil & gas contain large amounts of hydrogen sulphide. At high temperatures, when hydrogen atoms diffuse into the steel, hydrogen molecules form an internal defect or inclusion that usually migrate to become a small delamination. Over time, this can form voids or blisters which lower the equipment MAWP (maximum allowable working pressure) and may lead to equipment failure.
