Compromised “kissing bonds” in solid-state welds are tough to identify with conventional ultrasonic testing. Recently, EWI investigated using the ultrasonic process known as full matrix capture/total focusing method (FMC/TFM) to detect kissing bonds in intentionally fabricated kissing bonds, and found that these weak welds could be positively identified. This promising research is discussed in Detection...

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...
