As new energy technologies continue to proliferate worldwide, many leading companies within the sector are showcasing their technological prowess across the new energy supply chain. Han’s Photonics, a subsidiary of Han’s Laser and a leader in high-end fiber lasers, has introduced the latest generation of their ABS series ring-spot lasers. This third-generation series is gaining widespread recognition from customers due to its efficiency, reliability, and stability.
New Energy Three-in-One Laser Welding System
Han’s Photonics has developed a new energy three-in-one welding system that includes a laser, a welding control cabinet, and a galvanometer welding head. At the core of this system is a self-developed welding control card, which enables real-time monitoring and calibration of welding power. This feature ensures that the laser operates efficiently and stably over extended periods. Currently, several of these lasers have been in continuous 24/7 operation at customer sites for over six months, achieving a welding pass rate exceeding 99.5%. This outstanding performance has garnered widespread acclaim from leading companies in the industry.

Advantages of the New Energy Welding Solution
The laser welding machine tailored for the new energy sector offers several key advantages:
Low Heat Input and Minimal Spatter
This minimizes thermal distortion and material waste, ensuring high-quality welds.
Reduced Welding Porosity and Enhanced Aesthetic of Weld Beads
This leads to better mechanical properties and a cleaner final product.
Stable Welding Energy with Excellent Consistency
This reliability ensures uniformity across all welds, crucial for high-volume production.
Pre-, In-, and Post-Weld Inspection Capabilities
These features provide comprehensive quality control, reducing the likelihood of defects and rework.
High Welding Speed and Efficiency
This translates to faster production cycles and reduced operational costs.
Application Case: Battery Tab Welding for New Energy Applications
The ABS series variable-spot fiber lasers developed by Han’s Laser are instrumental in the production of battery tabs for new energy applications. Utilizing a ring-spot to preheat materials and soften the keyhole, these lasers significantly reduce spatter by over 90%, resulting in more stable penetration and smoother welds. This technology ensures high-speed, high-quality welding of various components in power batteries.
