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 of Kissing Bond in Solid-state Welds with Full Matrix Capture and Total Focusing Method (FMC/TFM), a paper by EWI Senior Technology Leader Oleg Volf.
