Recently, the Ministry of Human Resources and Social Security issued the "Decision on Commending the 15th China Skills Award and National Technical Experts", and Wu Qingfu, an employee of Weihua Co., Ltd., won the honorary title of "National Technical Expert". The China Skills Awards and National Technical Experts are the highest government awards in the field of skilled talents in my country. The highly skilled talents who are commended are all outstanding representatives of skilled talents in the country. Since 1995, a total of fifteen sessions of selection and commendation of outstanding high-skilled talents have been carried out across the country.
Wu Qingfu has been engaged in welding work for 22 years, and has participated in many major domestic and foreign projects such as the National Torch Program, the National 863 Project, export products, and nuclear power products. He has made more than 40 technological innovations and solved more than 10 core welding technical problems. He has designed more than 30 sets of tooling, obtained 5 national invention patents, more than 20 utility model patents, and participated in the formulation of 1 local standard and 1 group standard. He has been awarded honorary titles such as National Model Worker, China Machinery Industry Hundred Craftsmen, National High-Skilled Outstanding Workers in Heavy Machinery Industry, Central Plains Leading Talent (Central Plains Thousand Talents Plan), and Henan Province Technical Expert.
01 Working hard to solve problems Mobile hoists are important equipment in water conservancy projects. The T-shaped penetration welding of its main components is a technical problem in the industry. After many experiments, Wu Qingfu finally mastered the penetration welding operation skills of T-shaped joints. The first-time pass rate increased from 80% to more than 95%, solving the problem of full penetration of T-shaped welds, and taught the operation methods to each team. The conventional assembly method for the gantry of a container gantry crane is pre-assembly, which requires a long construction period, high costs, and certain safety risks. Based on many years of practical experience, Wu Qingfu actively pioneered and innovated based on the installation accuracy requirements, which improved the efficiency by 30%, ensured the assembly accuracy, eliminated safety risks, and solidified it into a standard operating method for promotion within the company.
In response to the current situation that the market share of lightweight cranes is increasing year by year, Wu Qingfu designed and produced a set of 5-125t assembled lightweight crane trolley assembly and welding equipment, which is suitable for assembly and welding of lightweight trolley components. It has high precision, small welding deformation, and increases production efficiency by more than 20%, realizing mass production and interaction of components.The interchangeability requirements lay a solid foundation for the transformation of gantry cranes into standardized and mass production. Wu Qingfu presided over the establishment of a robot welding workstation for the inner seam of the main beam of a general-purpose bridge crane, which is suitable for the welding of 64 standard products. He summarized and solidified more than 100 sets of welding data. The first-time inspection pass rate reached 100%, and the welding efficiency increased by more than 40%. It freed welders from the harsh environment of narrow space and serious smoke and dust, saving more than 400,000 yuan in labor costs every year. The put into use of this set of robot workstations marks a substantial breakthrough in the field of intelligent manufacturing for the general bridge crane industry.
02 Actively improve quality assurance Wu Qingfu led a number of quality improvement projects, including the "Development of Manufacturing Process Methods for Crane Walking Platform Railings" project, which increased the production efficiency by more than 50% and the first-pass inspection pass rate to 98%. This quality improvement won the first prize for quality management results in Henan Province; For the quality improvement project "Improving the Qualification Rate of Button Welding of Truss Beam Channel Steel", by improving the process equipment and operating methods, the welding speed was significantly improved, and the qualification rate was increased from 85% to over 95%. This quality improvement won the second prize of Henan Province Quality Management Achievements.
03 Working tirelessly to promote inheritance Based on many years of work experience, Wu Qingfu compiled a number of operating procedures such as the "Bridge and Gantry Crane Welding Operation Method" and the "Steel Structure Manufacturing Process Code", and distributed them to each team to guide the company's front-line welders to operate in standardized operations.
