Ultrasonic Testing is a safety inspection method that uses sound waves (like the technology used in medical ultrasounds) to check for problems inside industrial equipment without having to take it apart. It's similar to how doctors use ultrasounds to look inside the body, but technicians use it to examine things like pipes, welds, and metal structures. This method helps find hidden cracks, weak spots, or other issues that can't be seen from the outside. Companies rely on this testing to prevent equipment failures and maintain safety standards. You might also see it referred to as UT, NDT (Non-Destructive Testing), or Ultrasonic Inspection.
