Manual means of performing NDT and human evaluation of the results is trending more and more to automated, digitized and artificial intelligence interpretation of the results whenever economically possible.
Manual or human manipulated NDT is still the primary means of performing Nondestructive Testing (NDT) in unique or one-off applications. Mechanical aids and/or computer assisted manipulation and scanning devices can reduce data gathering time on the site of the item being inspected.
Digitalizing data for everything that can be thought of is a continuing trend. The computer can then perform analysis above and beyond the human analysis of analog data.
