Description

technical field

[0001] The invention relates to the field of underwater detection, in particular to an underwater digital ultrasonic flaw detector based on an underwater robot (ROV). Background technique

[0002] Underwater nondestructive testing technology is a new technology developed with the rise of underwater engineering. In recent years, due to the sharp increase of offshore facilities, such as submarine pipelines and production platforms, how to ensure the safe operation of offshore facilities is very important. In addition, the underwater monitoring of large ships has also received more and more attention. At present, the widely used underwater non-destructive testing methods mainly include: visual inspection method, ultrasonic thickness measurement and ultrasonic flaw detection. Underwater ultrasonic flaw detection is an important content of underwater detection, and it is the main means to find internal defects of underwater metal structures. Using underwater rob...
