On September 26th, the “2025 Changan Automobile Forward-Looking Technology and Ecological Chain Cooperation Exhibition & Exchange Meeting” was held at Changan Automobile’s Global R&D Center in Chongqing. Xinnashi Intelligent Technology made an appearance at the event with three innovative products: the NewOCT Weld Penetration Detection Welding Head, the NewScan-3D Galvo Flying Welding Head, and the NewFO3 Wire-Feed Brazing & Fusion Welding Head. It discussed the cutting-edge trends of smart manufacturing with industry partners, attracting great attention from the participants.

1.Three Innovative Solutions to Boost the Upgrade of Smart Manufacturing in New Energy Vehicles

NewOCT One-Stop Solution for Weld Penetration Detection

For new energy vehicle manufacturing, 100% full inspection of weld penetration is the core of welding quality. This solution enables real-time online measurement of weld penetration in laser flying welding, with a detection accuracy of ≤10% and an axial resolution of 0.02mm. It supports one-click switching of multiple process parameters, effectively avoiding misjudgment of defects such as cold welding, missing welding, and over-welding, achieving a 100% detection accuracy rate and significantly improving the product yield rate.

NewScan-3D One-Stop Solution for Galvo Flying Welding

Relying on breakthroughs in core localized technologies, the equipment cost has been reduced by over 30%, while it also features high-efficiency, high-precision, and high-reliability welding performance.

With independent optical design combined with multiple safety controls, and by virtue of position triggering and real-time height compensation technologies, the laser output position accuracy of ±0.02mm is achieved. The intelligent process parameter library significantly shortens the debugging cycle, and multiple safety strategies avoid the risk of misoperation.

This solution has been successfully applied to the key welding of body-in-white (BIW) and power batteries, with the welding speed increased by over 40% compared with traditional methods.

NewFO3 One-Stop Solution for Laser Wire-Feed Brazing & Fusion Welding

This high-end domestic laser welding equipment is independently developed by Xinnashi. It features high-precision weld seam tracking, automatic welding spot size compensation, and an optional stirring function, which effectively ensures welding stability.

The system is compatible with multiple processes including brazing and fusion welding, enabling low heat input and high-quality weld seams while effectively reducing workpiece deformation. It also boasts functional extensibility: it is suitable for any type of laser light source, easy to expand, and can be quickly integrated into an integrated system with external systems.

二、Brilliant Speech Drives New Energy Vehicle Manufacturing Toward a New Era of Intelligence and Efficiency

Liu Gang, Solution Director and Process Expert of Xinnashi, delivered a keynote speech titled “Xinnashi Laser Spiral Welding Technology Promotes Quality Improvement, Efficiency Enhancement and Cost Reduction in New Energy Vehicle Manufacturing” at the Exchange Day. He pointed out that developing high-end laser welding and intelligent production lines is the key to complying with the automotive industry’s trends of “electrification, intelligence and lightweighting”, enhancing industrial competitiveness and ensuring the security of the industrial chain.

As an innovative process, Xinnashi’s laser 3D galvo flying spiral welding technology features fast welding speed, high connection strength, excellent energy efficiency and wide application scenarios. It can reduce equipment costs by over 40%, effectively driving the transformation of new energy vehicle and power battery manufacturing toward high efficiency, intelligence and energy conservation.

Work Together to Facilitate the High-Quality Development of Automotive Manufacturing

During this Exchange Day event, Xinnashi fully demonstrated its outstanding technological capabilities and vigorous innovative vitality in the field of advanced automotive manufacturing. Looking ahead, Xinnashi looks forward to further deepening cooperation with Changan Automobile and industry peers, actively exploring the innovation paths and application prospects of advanced manufacturing technologies, and working together to help the automotive manufacturing industry enter a brand-new stage of higher-quality and more sustainable development.
