Abstract: Standard digital transformation is inevitable trend of standardization work to adapt to global digital development, welding materials as a wide range of basic joining materials, should strive to achieve and run with international development process in the process of standard digital. “General Principles of Quality Evaluation of Welding Materials” is being formulated and improved, in view of demand for advanced products in national major equipment manufacturing industry and development trend of green manufacturing, through analysis and understanding of core elements and connotation of standard digitization, project and principle of evaluation of product quality are put forward, and implementation and development of welding standard digitization are discussed and prospected in combination with technical ideas and characteristics in the formulation of welding material recognition.
