In the manufacturing process of nuclear power equipment,welding is the most basic,key and important technology. Its quality directly affects the overall quality of equipment and the operation safety of the whole nuclear plant. As the implementers of welding technology-welders and welding operators（hereinafter referred to as "welding personnel"）,their skills directly affect the quality of welding. According to the evolution and updating process of HAF603 "Management Regulations on the Qualification of Welders and Welding Operators for Civil Nuclear Safety Equipment",qualification standard for nuclear power welding personnel in China,and the comparison of the requirements of qualification and management of welding personnel between domestic and foreign regulations and standards,combining with our own experience in the qualification of welding personnel,a brief analysis and exploration are made for the exchange and discussion among colleagues.
