Facing the growing independent and controllable demand for welding materials in the field of high-end manufacturing, the traditional single-point R&D model has become difficult to meet complex challenges.In recent years, the collaborative innovation system of deep integration of ”industry, university, research and use" is becoming the core engine for breaking through the key core technologies of welding wire and accelerating the process of localization substitution.This model is usually led by the theoretical research and cutting-edge exploration of key universities or research institutes. Welding material manufacturing companies are responsible for the pilot transformation and industrialization, while downstream leading equipment manufacturing companies (such as shipbuilding groups and rail transit companies) provide the most realistic application scenarios and performance verification platforms.

The advantages of this closed-loop collaboration are significant.Universities and research institutes can use advanced microanalysis equipment (such as transmission electron microscopy, synchrotron radiation) and computational simulation methods to conduct in-depth research on the phase transition mechanism, strengthening mechanism, corrosion behavior and other scientific issues of weld metals, and provide theoretical guidance for the design of welding wire composition.The enterprise engineering team focuses on transforming laboratory formulas into stable and mass-produced processes to solve a series of engineering problems such as drawing, coating, and packaging.In the end, the product is evaluated for long-term and batch service under extreme working conditions on the client side, and the data and suggestions fed back are fed back to optimize upstream R&D and production, forming a virtuous circle of continuous improvement.

At present, this model has made key breakthroughs in the localization projects of many “stuck neck” materials such as superalloy welding wires for aerospace engine components, titanium alloy welding wires for deep-sea pressure-resistant housings, and heat-resistant steel welding wires for ultra-supercritical power stations.It not only accelerates the efficiency of the transformation of technological achievements, but also cultivates a composite talent team that integrates basic research, engineering application and market demand, laying a solid talent foundation for the long-term innovation and development of the welding wire industry.
