Battery Nickel Steel Strips Spot Welding Machine

Technical Excellence

The Nickel Steel Strips Spot Welding Machine is an industrial welding solution designed to join nickel steel strips with consistent weld strength and surface quality. Developed for battery manufacturing applications, the machine combines medium-frequency inverter DC welding technology with pneumatic pressure control, a dedicated welding fixture, and an integrated electrical control system.

The medium-frequency inverter welding power supply operates at 1000 Hz, converting electrical energy into DC welding current to improve energy efficiency and reduce losses compared with conventional mains-frequency welding systems. The equipment is designed to provide controlled welding performance while supporting the production requirements of workpieces with multiple welding points and changing specifications.

The machine incorporates a pneumatic vertical pressurization mechanism to apply welding pressure and hold the workpiece in position. Its positioning mold supports accurate workpiece placement, while the programmable controller enables operators to adjust welding time, current, pulse count, and other process parameters. Multiple welding specifications can be stored for convenient use across different production requirements.

A circulating water-cooling system helps manage heat generated during welding and supports stable operation. Additional functions, including weld-point counting, preset weld-point settings, fault diagnostics, and audible and visual alarms, assist operators in monitoring the process and maintaining equipment performance.

Semco Infratech provides battery manufacturing and testing equipment for industrial applications. The SI-JG-NSWM is suitable for manufacturers seeking a controlled, energy-efficient spot welding solution for nickel steel strip joining, subject to confirmation of the workpiece dimensions and welding requirements.
