All bodies at finite temperature emit electromagnetic radiation. The hotter the object the more energy it radiates and the shorter the wavelength it emits. Room temperature objects emit in the long wavelength infrared (LWIR) spectrum range. The ability to produce a temperature map of an object is very useful in nondestructive evaluation (NDE). Static IR...

Ultrasonic metal welding is an excellent process for the joining of dissimilar metals in electric vehicle batteries. The ability to monitor the joint during the welding processes is important for identifying faulty welds and avoiding product failure. Recently, EWI has made some important progress in in-situ monitoring for ultrasonic metal welding. Applications engineer Lindsey Lindamood...

In sheet metal stamping, material property variations between batches of an incoming coil can significantly affect part quality and increase scrap rate. This issue is far more pronounced for emerging third generation (Gen III) high-strength steels. Because there are batch discrepancies, major automotive OEMs and tier 1 suppliers are interested in both real-time measurement and...
