Review:In the welding process, friction stir welding, as the preferred connection technology of aluminum alloy, has also been widely concerned and applied in the field of automobile industry.

From February 24 to 25, 2022, the second 2022 China Automotive Aluminum Alloy Developer Forum & 2022 China Electric Vehicle Battery Pack Lightweight Connection Technology Forum was held in Shanghai. In this event, Guangzhou Risong Weldstone Intelligent Equipment Co., Ltd. (hereinafter referred to as Risong Weldstone) released the "key technical solutions for battery tray manufacturing of new energy vehicles" at the discussion meeting of battery tray welding quality control technology, and Yang Kun, marketing director of Risong Weldstone, made a related keynote speech.

Risong Weldstone has mastered the core connection technology and process in the field of battery tray manufacturing of new energy vehicles, including friction stir welding (FSW) workstation and arc welding (CMT) workstation, and has complete production line integration ability. In the welding process, friction stir welding, as the preferred connection technology of aluminum alloy, has also been widely concerned and applied in the field of automobile industry.


 

Risong Weldstone successfully applied friction stir welding and arc welding to the intelligent and flexible production of battery tray of new energy vehicles - independent core technology can effectively solve the connection problem of lightweight battery tray and provide a complete solution for production and manufacturing.

 


In his speech, Yang Kun said that the concerns of Risong Weldstone's friction stir welding technology and equipment in the welding of battery tray of new energy vehicles are: first, the weld quality, welding speed and post welding deformation of battery tray bottom plate of new energy vehicles; Second, weld quality and intelligent welding in the assembly welding of battery tray production line of new energy vehicles. The design purpose of friction stir welding equipment of Risong Weldstone is simple, fast and effective. The product has enough rigidity to offset the four forces of FSW. The structure shall not interfere with the welding implementation and protect the product surface.

In the key technical scheme for the intelligent production of battery tray for new energy vehicles, Risong Weldstone can realize the automatic hydraulic pressure in the welding of battery tray bottom plate and production line assembly, ensure the rigid state of workpieces, and realize the automatic loading and unloading of robots. At the same time, the welding deformation can be effectively controlled and the welding quality can be guaranteed by the array evenly distributed holding method.

 

He mentioned that one of the process cores of Risong Weldstone friction stir welding equipment is the independently developed r-sstool technology mixing head design. The raw materials and heat treatment used by the mixing head determine the service life of the mixing head, and the shape design of the shaft shoulder and mixing needle of the mixing head determines the welding speed and weld quality.

The r-sstool technology mixing head independently developed by Risong Weldstone has many advantages and characteristics:

Ø Long service life: low wear rate, more than 2000 meters;

Ø high welding speed: ensure the welding quality, and the welding speed is more than 2000mm / min;

Ø strong compatibility: it has better metal accommodation, anti misalignment ability and strong anti gap ability;

Ø diversified for different structures or needs: 1mm mixing head: 6-1, 7-1, 8-1, etc; 2.5mm mixing head: 8-2.5, 9-2.5, 10-2.5, 12-2.5, etc; 3.5mm mixing head: 10-3.5, 12-3.5, etc.

 

 

The friction stir welding equipment of Risong Weldstone has high weld quality, perfectly solves the problems of cracks and pores in the welding process, and there is no flash, splash and no need to add welding materials, so as to save grinding, cleaning process and production cost, and truly realize automation. Its advantages and economic applicability make it the best choice for welding process manufacturers with high welding requirements for lightweight materials.

Limited by various factors such as battery weight, mileage, energy conservation and emission reduction, the lightweight of battery driven new energy vehicle body is the first problem to be solved in its production and manufacturing. It is urgent to tackle the key problems of lightweight material connection technology related to new energy vehicle manufacturing and the R&D and manufacturing of intelligent equipment.

 

As an excellent robot and intelligent manufacturing system solution provider, Risong technology has been committed to providing customers with complete sets of intelligent and flexible manufacturing system solutions. Especially in the automotive field, Risong technology has been helping major global well-known automobile manufacturers build production lines and accumulated rich experience in the whole line construction. It can control well in terms of production rhythm, logistics, production line layout and field application, so as to ensure customers' production accuracy Strength and stability requirements.

For the construction of the battery tray production line of new energy vehicles, as a subsidiary of Risong technology, Risong Weldstone can directly cut into the automobile industry and build it more appropriately with the standards of automobile production. In the future, with the gradual expansion of the market development scale, the production line capacity of Risong wells is enough to match the larger carrying capacity and create a larger line body.

 

At present, the application of Risong Weldstone lightweight material manufacturing solution is far beyond new energy vehicles. The company's friction stir welding equipment has been mature and applied in important links of 5g communication base station components, BMS radiator and other product processing, and has won customer satisfaction and praise with superior process performance.

 

In the future, Risong Weldstone and its series of intelligent equipment such as friction stir welding and arc welding will continue to make breakthroughs in the application of all walks of life with the advantages of all aspects, effectively occupy the emerging industrial market, continue to develop, and seek a leading position in the development of intelligent manufacturing technology and industry.
