Non-linear acoustics (NLA) offers unique possibilities in the detection of micron-scale flaws, often superior to radiography and other NDT alternatives. Complementary NLA techniques also provide a portfolio of solutions, from rapid triaging (‘go/no-go’) to high-resolution automated scanning. This paper illustrates the range of options, discussing NLA capability with case studies in metal bonding, composites, creep and additive manufactured parts.
