From October 23rd to 25th, the 5th Changzhou International New Energy Engineering and Industry Development Conference was grandly held. This event, themed “New Energy Intelligent Manufacturing and the Internationalization of the Industrial Chain,” focused on key technologies such as new energy batteries, electric drive systems, and drive motors. As one of the invited companies, Newlaz shared the latest technological achievements through engaging speeches and on-site exhibition booths, discussing market expansion opportunities in the new energy smart manufacturing industry with industry peers.
At the Battery Digital Intelligent Manufacturing Engineering and Testing Technology Special Forum, Newlaz Key Account Manager, Li Renzhi, shared how 3D laser flight welding and penetration detection technology can enhance the efficiency and quality of the manufacturing of the three major electrical systems. He pointed out that 3D laser flight welding uses robot control of the laser galvanometer for scanning welding, eliminating the movement time of the robot/external motion mechanism, achieving non-contact welding with the workpiece, greatly improving welding efficiency, and resulting in high-strength and stable welds. This technology is especially applied in automotive manufacturing and the welding of Busbar in power batteries.
The combined application of flight welding and penetration detection technology allows customers to inspect penetration without breaking the inspection, which can effectively reduce the time required for manual checks and overall enhance the comprehensive efficiency of the production line. Whether it is in-process penetration detection or post-weld appearance inspection, these technologies can accurately locate problematic weld points. The application of these technologies can significantly improve the efficiency and quality of manufacturing for the three major electrical systems of new energy vehicles (battery, motor, and electric control), which is of great importance to the rapid development of the new energy vehicle industry.
The NewScan-3D galvanometer flight welding system showcased at the forum is an efficient welding solution specifically designed for the new energy power battery industry. This system has various swing process modes, capable of achieving rapid welding while maintaining high precision. During the flight welding process, the galvanometer and external motion mechanisms compensate for positions in real-time through communication, ensuring the accuracy of the welding position. This technology is notably effective in improving quality and efficiency in the welding of Busbar in square battery (cylindrical battery) Pack modules and the welding process of cylindrical battery cells and current collectors. By increasing the welding speed of individual electrode columns and shortening the welding time for the entire battery box, it also ensures that the appearance and penetration width of the welds meet higher standards.
Newlaz newly launched NEWOCT Penetration Detection System has attracted the attention of many professionals. This welding head combines flight welding and penetration detection technology, capable of real-time online measurement of penetration depth, accurately reflecting the data of weld penetration depth. With strong anti-interference capabilities, it is not affected by factors such as lasers during the welding process, accurately detecting the penetration depth of weld points in real-time, with a detection accuracy of ±0.1mm. It can effectively solve quality issues that may arise during the laser welding process, significantly reducing the defect rate of products. It is suitable for various scenarios such as power battery welding inspection, body and component welding inspection, and IGBT copper bar welding inspection, providing strong assurance for improving welding quality and efficiency.
In the new energy industry, laser welding technology is key to improving production efficiency and ensuring safety and stability. It is not only an important tool in modern manufacturing but also a key factor in driving the industry towards intelligent development. NewNishikawa, as a high-tech company deeply engaged in intelligent high-power laser precision welding technology, has always adhered to independent research and development and technological innovation. It continuously promotes the development of laser welding towards intelligence, automation, and greenization. What Newlaz provides is not just products, but also high-cost-performance laser welding system solutions for various industries such as new energy vehicles, power batteries, and electric drives.
