Phased Array Ultrasonic Testing of Stainless Steel Pipe Welds

Materials Evaluation, 2023
Weld inspection of stainless steel pipes and pressure vessels is one of the most challenging and difficult inspections for ultrasonic testing. This is due to variations in grain structure and associated anisotropy. Anisotropy causes grain scattering and adversely affects propagation of sound waves.

Ultrasonic phased arrays for nondestructive testing

NDT International, 1987
Abstract Although ultrasonic phased arrays are potentially ideally suited to many applications in NDT, their use in practice is limited by the complexity of array probe manufacture and the bulk and cost of the associated electronic control instrumentation.

Composite material ultrasonic phased array testing

AIP Conference Proceedings, 2019
This thesis discusses the results of an ultrasound testing of a fiberglass plate using a flaw detector with phased antenna arrays. Fiber-reinforced laminated composite materials are widely used in modern light-weight structures. Non- destructive experiments carried out on the composite plate with artificial defects. The examined 5 mm sample was made of

Fabrication of Weld Defects for Phased-Array Ultrasonic Testing

2018 International Conference on Applied Engineering (ICAE), 2018
Artificial weld defect specimen has an important role in the training of non-destructive testing personnel. It simulates real defects occur in the actual inspection. Challenging factor in manufacturing weld defect is creating realistic defects. The methods in this study are deliberately to produce poor weldment and accommodate certain weld defect such ...
