       The global ban on fuel vehicles has been put on the agenda. Major car factories have launched new energy electric vehicles, and lightweight has become an important goal for new energy vehicle manufacturers. At present, most manufacturers use aluminum alloy as lightweight body materials, so the welding quality, lightweight level and air tightness requirements of vehicles are improved accordingly. At this time, a new welding technology, stir friction welding, has been widely used in automobile manufacturing industry with its advanced, green, safe and reliable technology characteristics, and represents the important direction of welding manufacturing of new energy vehicles in the future.

 
Friction stir welding is to make use of friction heat of the mixing head and the end face of the workpiece to reach the thermoplastic state and then to forge quickly, so as to realize the solid connection of the welding. Based on these advantages and the development strategy of national intelligent manufacturing and green environmental protection, the friction stir welding technology has rapidly shifted from laboratory to large-scale engineering, which is used in many industrial fields such as automobile manufacturing, aerospace, ship manufacturing and rail vehicle manufacturing.
 
Early friction stir welding was mainly realized by CNC machine tools. With the improvement of users' requirements for equipment flexibility, these large CNC machines with large size, flexible operation and difficult to work together can not meet the production demand. Therefore, enterprises began to use heavy-duty robots to replace them and integrate industrial robot system with advanced friction welding equipment.
 
In order to further popularize the application of stir friction welding technology in the field of new energy vehicle manufacturing, the 51robot one-stop service platform of Harbin Industrial Robot Co., Ltd. has launched FSW robot system, and provided a complete set of services including the design and manufacture of welding production line, installation and commissioning of supporting robots, The high efficiency and stability of friction welding system of robot can help enterprises get more production benefits.
 
Friction welding technology with robot
 
The combination of robot and stir friction welding technology is an important development direction of friction stir welding equipment in recent years. When the automobile manufacturer is equipped with the production line of friction stir welding, many problems need to be considered, including the design of heavy-duty industrial robot body and friction stir welding machine. For a new process, the integration of various sensing control systems should be considered, The whole process needs the support of high-end technology or knowledge-based talents for process path planning and collaborative control technology.
 
In view of the selection and installation and commissioning of industrial robot body in the friction stir welding of robot, 51robot platform can ensure the first-class product quality through comprehensive cooperation with well-known robot enterprises at home and abroad, so that users can easily complete the selection according to the application and personalized requirements.
 
In the process of production, the cooperative work with positioner or multiple robot systems should be considered in the production process of friction welding, and the process flow should be re planned to realize the flexible manufacturing of "small batch and multi varieties". Therefore, the 51robot platform Harbin Wanzhou subsidiary focuses on the research and development of intelligent heavy-duty robot stir friction welding, intelligent multi freedom stir friction welding and other technology research and equipment production, providing more in-depth technical support for intelligent upgrading of production line and meeting the diversified needs of users.
 
New ideas of industrialization
 
Industrial robot makes the friction stir welding system more flexible, thus expanding the application market of welding operation. The new system can be used in batch welding manufacturing of complex structure products, and can further improve the welding automation and production efficiency. This is enough to be reflected in the first domestic production line of pack full automatic stir friction welding box of new energy vehicle built by 51robot. The biggest highlight is to solve the compatibility, the whole line beat and efficiency through the design of "high flexibility", "high automation" and "high production efficiency". The pack box welding line is designed as a whole module. The independent friction stir welding system can not only connect with the automatic production line to form the whole production line, but also can be used separately, which can meet the needs of customers in two different production modes: small batch, customization and mass production.
 
In the friction stir welding, because of the high flexibility of robot, the welding process is stable and no human interference is needed, so the welding quality is significantly improved, and it is conducive to reduce the production cost. According to the industry statistics, the cost of single piece welding of friction stir welding is 20% lower than that of robot argon arc welding, only half of the welding cost of multi axis friction stir welding equipment. Therefore, the friction stir welding with robot has a significant cost advantage in large-scale industrial production.
 
In addition, the friction stir welding is green, energy-saving and efficient, and can be used in complex structure welding, such as plane two-dimensional and spatial three-dimensional, and can expand the robot workspace freely through the external axis. At present, 51robot provides intelligent multi degree of freedom stir friction welding robot, 3D stir friction welding and other technologies, and has industrial constant pressure control system, multi degree of freedom to realize 3D surface welding, with high automation integration and expansibility. This flexible production mode of the hybrid friction welding combined with robot has become a new idea of industrialization.
 
The technical dispute of new energy automobile enterprises
 
In recent years, China's new energy vehicles have also achieved a leap of industrialization and scale development. In 2017, China's new energy vehicles output was 794000, with sales of 777000, up 53.8% and 53.3% year on year respectively, ranking the first in the world for three consecutive years. It is predicted that the market space of new energy vehicles in China will reach 14 trillion yuan from 2018 to 2030.
 
Huge market indicates great competition pressure. In addition to the domestic enterprises entering the new energy vehicles, foreign enterprises are also eager to wait for opportunities to turn over to "the later" by virtue of technical advantages, and technology competition has become the key.
 
It is understood that half of the industrial robots in service are used for welding. Therefore, friction stir welding technology of robot has become the focus of the industry. New energy vehicle manufacturers have arranged full-automatic friction stir welding, hoping to obtain more efficient, more flexible and lower cost production process. Therefore, enterprises need to control and test robot body, welding head, control and measurement system Process planning and other aspects of optimization.
 
At present, 51robot, with the help of professional tools and talents, customized automatic welding production line for domestic large and medium-sized and small-sized industrial robots users. At the same time, thousands of famous robot manufacturers at home and abroad have been assembled on the platform to realize the following aspects: providing industrial robot body, machine man standard system, system integration, remote health monitoring, maintenance and maintenance The whole life cycle ecological chain of the circular industrial robot is integrated from technical training to robot renovation and remanufacturing.
 
With the decline and exit of domestic financial subsidies and the gradual emergence of the substitution effect of new energy vehicles on traditional fuel vehicles, the new energy vehicle war between China and foreign countries may erupt in five years, and the market competition will be extremely cruel. Domestic enterprises need to improve the level of R & D as soon as possible, master core independent technology and launch competitive products to occupy the local market. The application of friction stir welding of robots has become an important part of the enterprise to intensify the layout.
