Portable Laser Welding Machine with Adjustable Swing Arm, Built for Lithium Cell and Battery Pack Welding

This swing-arm laser welding machine is purpose-built for lithium battery cell and battery pack welding tasks. It integrates an adjustable swing arm, a precision laser welding head, an intuitive touch screen control system and a standardized cable management system. It is developed to meet the high-standard welding requirements of new energy battery workshops, covering cell terminal welding, tab welding, busbar connection and battery module assembly.

Compared with traditional spot welding equipment, laser welding delivers concentrated energy, a narrow heat-affected zone, stable welding strength and low internal resistance. The flexible swing arm design breaks the limitation of fixed working positions, allowing operators to easily reach different areas of battery modules. With neat cable routing, the whole machine looks tidy and reduces the risk of cable wear and interference during frequent movement. It is widely used for battery R&D prototypes, small-batch trial production and mass battery pack manufacturing.

The multi-joint adjustable swing arm supports multi-direction rotation and position adjustment. It features a large working range and a stable support structure. The welding head can be freely moved above the workbench to adapt to different battery layouts, such as dense cylindrical cell arrays, stacked prismatic modules and irregular pack structures. The swing arm runs smoothly without shaking, ensuring stable positioning of the laser head during welding.

The dedicated laser welding head realizes focused laser output. It can form continuous or spot welding seams with high precision. The welding effect is clean, with little spatter, firm fusion and stable conductivity. It is suitable for welding copper, nickel and copper-nickel composite materials commonly used in lithium batteries. The laser head is easy to maintain and replace, supporting long-term continuous production.

The industrial touch screen is the core operation panel of the equipment. All welding parameters can be set, adjusted and stored on the screen, including laser power, welding speed, pulse frequency, dwell time and waveform. Multiple sets of welding recipes can be saved for different materials and thicknesses. Users can switch parameters with one click to quickly adapt to different battery products. The system also provides real-time status monitoring and fault prompt functions for convenient operation and troubleshooting.

The machine adopts a standardized cable arrangement design. All optical cables and signal cables are arranged neatly, avoiding messy winding, pulling and abrasion caused by frequent swing of the arm. This design improves workshop safety, reduces cable failure rate and makes daily maintenance easier.
