Ultrasonický průvodce Wave Testing

Ultrasonicc guided wave testing (GWT) has evolud from a niche pracatory method into a widely deployed field inspekton tool. Modern GWT systems use multiple piezoelectric rings or magnetostrictive transducers to generate low- frequency waves (typically 20-100 kHz) that travel along thee wall for tens of meters.
