Automatic ultrasonic testing system for piping welds

The working principle and composition of the automatic ultrasonic testing system for steel tube welds are introduced. By this system, testing can carry on automatically, the data obtained from in-service inspection can be analysed by computer and remote-control can be realized too. It greatly reduce nuclear radiation amount which the inspectors absorb during the inspection of the equipment in the future. The examination results can provide data reference for safe operation of nuclear power plant
