Abstract: In response to the challenges and difficulties encountered by Chinese equipment manufacturing enterprises in the application of friction stir welding technology in the past 20 years,the system has reviewed the friction stir welding for more than 20 years in equipment development,mixing tool development,weldable materials,welding processes,product applications. Application research and basic research in the field of welding formation mechanism. Through systematic investigation of equipment manufacturing enterprises,it is found that the bottleneck problem faced by the application of friction stir welding engineering is mainly due to insufficient basic research depth,inaccurate grasp of systemic mechanical requirements of medium and high-end equipment,and insufficient research and development capabilities of high-efficiency and low-cost mixing tools. The high-end dedicated process research and development strength is weak,the operational skill-oriented talents have no system training norms,etc.,and points out that integrating research resources,strengthening basic research,and establishing overall solutions from equipment development,process development,processing,and talent training. High-tech companies are the fundamental way to effectively solve the above-mentioned bottleneck problems,and pointed out the direction for the friction-welding welding method in the future efficient engineering application and research and development of Chinese equipment manufacturing industry.
