Handheld Laser Welding Machine for Lithium Batteries: Designed for New Energy Applications

The growing demand for flexible, precise joining solutions in the new energy sector has led to the development of specialized handheld lithium battery laser welding machines. These systems are designed to meet the unique challenges of lithium battery manufacturing and repair, particularly in module assembly, busbar connection, and enclosure sealing.

Purpose-Built for Battery Materials

Unlike general-purpose handheld welders, dedicated handheld lithium battery laser welding machines are optimized for common battery materials such as copper, aluminum, nickel-coated steel, and stainless steel. They offer fine control over pulse shape, duration, and peak power, which helps reduce spatter and porosity—critical for maintaining electrical conductivity and structural integrity.

Precision and Low Heat Input

Lithium battery components are sensitive to heat. Excessive thermal input can damage cells or degrade nearby materials. These handheld systems deliver focused energy with minimal heat spread, reducing the risk of thermal damage. The ability to adjust parameters on the fly allows operators to fine-tune welds for different joint types and material thicknesses, typically ranging from 0.5 mm to 2.0 mm.

Portability Meets Process Control

While maintaining the mobility of a handheld device, these machines often include digital interfaces for preset storage, real-time monitoring, and parameter traceability. Some models support data logging for quality assurance, making them suitable for both production and field service applications.

Applications Across the Battery Lifecycle

They are used not only in new new energy system assembly but also in maintenance, repair, and repack operations. Technicians can perform targeted repairs on battery packs without full disassembly, improving service efficiency.

A handheld lithium battery laser welding machine bridges the gap between industrial automation and manual flexibility. Haiwei Laser’s models offer stable performance, simple operation, and consistent weld quality, with intuitive controls for quick adoption. When selecting a system, prioritize stable beam quality, material-specific parameter presets, and safety features to ensure reliable, high-quality welds in lithium battery applications.
