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 ...

Researchers have improved flaw detection to increase confidence in metal parts that are 3D-printed using laser powder bed fusion. Researchers at the Department of Energy's Oak Ridge National ...

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 ...

Observations on nodal and loop analysis that can save a fair amount of scribbling of equations when using Kirchhoff's laws. In a previous Idea for Design, Anshi Chen outlined a method for analyzing ...

To ensure that the speed of composites fabrication keeps pace with customer demand, the ability to inspect and monitor composite part quality must become an integral part of high-rate part ...

Electron-beam inspection is proving to be indispensable for finding critical defects at sub-5nm dimensions. The challenge now is how to speed up the process to make it economically palatable to fabs.
