Inertia welding is a well-established, friction-based, solid-state joining process. Many different applications use this welding process, ranging from aircraft engine parts to air bag inflators to hand tools. Process parameters associated with inertia welding (spindle speed, welding force, inertia, and displacement) have been widely studied since the process gained traction in the late 1960s. One...

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...
