NDE and Inspection (Page 6)

The integration of advanced high-strength steels in automotive body-in-white manufacturing has made vehicles lighter, improved crash performance, and reduced noise, vibration and harshness. However, the use of AHSS materials has also been correlated to spot weld cracking, especially with Gen 3 steel grades. EWI’s new H-coupon test was developed to assess the influence of gap...

In-situ process monitoring has been around for a while in most manufacturing industries – from the trained eye of a supervisor to an automated manufacturing execution system. Additive manufacturing (AM) is no different; it uses sensors to provide both a better understanding of the process and valuable data that can be analyzed to infer the...

While conventional flash thermography is ideal for polymer materials, it can be challenging when used with metals due to reflectivity of the component. With pulsed eddy-current-assisted thermography (PECT), ferrous and non-ferrous steels, as well as titanium, can be inspected without surface reflection interference. Internal research on flattened, painted, and steel pipe is ongoing at EWI...
