Abstract: Non-destructive testing (NDT) is a core technology for ensuring the quality and safety of industrial products, key components, and major equipment. The standardization level of the personnel certification system directly determines the professional capabilities of practitioners and profoundly affects the reliability of Chinese manufacturing products and their international competitiveness. This paper reviews the development history of NDT personnel certification systems at home and abroad, and systematically analyzes the industry pattern, existing shortcomings, and international advanced experiences of Chinese certification system. Combined with the manufacturing power strategy, the "Belt and Road" initiative, the demand for high-quality manufacturing development and international production capacity cooperation, it extracts core development directions such as standardization construction, international mutual recognition, digital transformation, and industry resource integration, and proposes feasible optimization paths. The research can provide theoretical references and practical basis for the unification, standardization, internationalization, and high-quality development of Chinese NDT personnel certification system.
