The course won the first prize in the Teaching Ability Competition of the 2022 National Vocational College Skills Competition and has been successively rated as a provincial-level quality course, a provincial-level quality resource sharing course, a standardized course in the national vocational education welding professional teaching resource library, a provincial-level "13th Five-Year Plan" and "14th Five-Year Plan" quality online open course, and a typical case of the provincial "Classroom Revolution". The course integrates real projects, seamlessly blending job, course, competition, and certification, and reconstructs five progressive teaching modules: "structural cognition - process design - material preparation - assembly - welding". At the same time, it takes "promoting heavy equipment culture, inheriting the spirit of the third-tier, practicing the spirit of craftsmanship, and bravely taking on the responsibility of strengthening the country" as the ideological and political main line, organically integrating ideological and political content into the curriculum and designing in the same direction to achieve a subtle and subtle educational effect and comprehensively enhance students' comprehensive vocational abilities.
