Abstract: Various typical problems of welding nondestructive testing in nuclear power engineering under the new situation were analyzed, and measures to improve management level were put forward. The results show that improving the management level of welding nondestructive testing in nuclear power engineering is based on improving the work quality, and emphasis should be placed on system management, performance management, cultural atmosphere, technology management and process control. Attention should be paid to the qualification of nondestructive testing personnel, the connection of welding repair and process testing, and the planning of nondestructive testing for important activities. The quality of welding and engineering can be effectively tested and verified after the essential quality of inspection was improved. Improving the management level of welding nondestructive testing in nuclear power engineering can promote the effective promotion of nuclear safety culture in nuclear power engineering construction.
