    1. Requires a high level of training to use and interpret results.
    2. Traditionally doesn’t keep a permenent record. ( modern ut machines do these days)
    3. Expensive machines and probes
    4. Limitated to specific joint geometrys and shapes and surface cobditions (very small very thin very rough and non homogeneous materials are difficult)
    5. linear defects orientated parallel to the sound beam may go undetected
