Recently, EWI conducted a study in which ultrasonic vibrations were applied to the wire drawing process to improve both final wire quality and process performance. This investigation demonstrated positive results in several areas including wire roughness, dimensional accuracy, microstructure, draw force, and strength. It also reduced the number of die passes required to complete the...

Welding of dissimilar polymers is becoming more commonplace in manufacturing. There are several key reasons for this trend. First, many new plastics are being used in environments where adhesives cannot be easily applied. Typical examples include medical products for which finding adhesives that pass FDA regulations and join materials with low surface energy (like polyolefins)...

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...
