On the morning of January 13, the friction welding technology project with a total investment of nearly 100 million yuan was officially started at Xi'an Aviation Base. After the project is completed and put into production, the technology will be gradually applied to the connection of aircraft structural parts to fill the gap in the application of this technology in the domestic aviation field.
The project undertaker Xi'an Guben Technology Industrial Co., Ltd. is a high-tech enterprise specializing in R&D, production and marketing of high-performance general-purpose special friction welding machines, friction welding products and related technical software. The company has mastered the most advanced and comprehensive friction welding technology in China, and the related technical achievements have won one of the national key new products, the first prize of the provincial and ministerial level scientific and technological progress, and the second prize.
The friction stir welding technique was invented by the British Welding Institute (TWI), which is considered to be the most attractive welding method since the advent of laser welding. Because the technology has a series of obvious advantages such as good joint quality, stability, high efficiency, energy saving, material saving and pollution-free, it has been widely used in aviation, aerospace, automobile, shipbuilding, petroleum equipment and other fields. Boeing, The aircraft produced by Airbus has already adopted friction welding technology in many parts, but it has not been widely used in aviation in China.
After the project is completed, it can form an annual production capacity of 200 universal friction welding machines and special friction welding machines, producing 30,000 tons of drill pipes, and build the country's largest friction welding technology research and development base.
According to the plan, the project will be completed and put into operation within two years, and the annual output value is expected to exceed 1.1 billion yuan.
