Precise Lithium Battery Spot Welder with Repeatable Alignment, Clean Fusion & Less Rework for Battery Pack Assembly

Adopting advanced micro-pulse instantaneous energy release technology, the machine outputs concentrated and accurate welding energy in milliseconds. The heat-affected area is extremely small, so it will not damage battery cell shells, insulating layers or internal chemical structures.

Compared with traditional large-energy rough welding, this technology ensures firm welding joints and flat welding spots with no blackening and no burn-through, greatly improving battery safety and cycle stability after assembly.

Equipped with a high-precision movable swing arm welding structure, the welding head can move freely in multiple directions with smooth operation and stable vertical pressure. It can accurately target dense cell arrangements, narrow-spacing terminals and multi-layer busbar overlapping positions.

The mechanical positioning accuracy is high, which completely avoids welding offset caused by manual operation errors. It greatly improves the qualification rate of finished battery packs and reduces repeated repair work.

Industrial high-definition touch screen visual operation with all welding parameters digitally adjustable, including pulse intensity, welding time, welding frequency and interval parameters.

The equipment can store multiple sets of customized welding process data. Users can quickly switch parameters according to different tab thickness, busbar materials and battery specifications, realizing a standardized unified welding effect for mass production. The system supports parameter locking to prevent arbitrary modification and ensure stable production quality.

Built-in high-precision energy feedback module automatically senses and compensates for grid voltage fluctuations. It maintains stable energy output over long periods, ensuring that the size, depth and firmness of each welding spot in the whole production batch are completely consistent.

The equipment is equipped with an enhanced large-flow heat dissipation structure. Core power components work at low temperature for long periods, without energy attenuation or equipment overheating failure during high-frequency continuous welding. It supports 24-hour uninterrupted industrial continuous production and offers strong durability.

Multiple safety protection functions include over-current protection, over-temperature protection, overload protection and short-circuit automatic power-off. In case of abnormal operation, the machine will automatically alarm and stop working to protect operators, equipment and battery products from safety hazards.

Micro-pulse instantaneous welding with a small heat radiation range will not cause hidden damage to the battery, ensuring battery pack safety and long service life.

Accurate positioning plus stable energy output and uniform welding spot size greatly reduce the defective rate and production cost.

Adaptable to various common battery materials and specifications, flexible for multiple production projects.

Digital parameter setting plus formula storage lowers the technical threshold for workers and makes standardized batch production easy to achieve.

Industrial-grade configuration, anti-fatigue operation, strong stability, low failure rate and minimal later maintenance.
