Figure 1. Ultrasonic testing using pulse echo and through-transmission methods. Pulse echo (left and center) uses a transducer that sends and receives ultrasound energy, producing both A- and B-scan ...
Evaluation of materials at greater depths with high resolution is one of the most enduring scientific challenges. Inspection and qualification of bulk components with microscopic defect features for ...
Cracking furnaces, operating under high temperatures and in a hydrocarbon medium, subject their tubes to complex stresses such as internal pressure, self-weight, fatigue, and thermal shock during ...
Dr. Park Chan Wook (Postdoctoral Researcher, Non-Destructive Metrology Group, KRISS); The Korea Research Institute of Standards and Science (KRISS, President Lee Ho-seong) has developed an ultrasonic ...
From large aerospace production systems to challenging small-scale honeycomb applications, LEA has already proven itself in ...
A Lawrence Livermore National Laboratory team demonstrated that a diagnostic incorporating surface acoustic waves—generated by laser-based ultrasound—could effectively and accurately evaluate laser ...
Ultrasound inspection is a non-destructive testing method that detects electrical emissions and mechanical conditions in equipment. Predictive and proactive inspection of rotating equipment is ...
Additive manufacturing (AM) techniques increasingly require novel non-destructive inspection methods able to fit smoothly within AM workflows, in particular for the detection of structural defects. A ...
A recent spike in battery-related fires has highlighted the difficulty of spotting flaws in their production. Rarely visible to the naked eye, these flaws can lead to serious battery malfunctions. The ...
Within the body of a high-voltage multi-layer ceramic capacitor, a gap-type defect is beginning its career of destruction. The defect may be a void within the ceramic dielectric, a crack within the ...
