Precision resistance spot welding machine: a quality revolution in the field of new energy welding

In the field of 18650 lithium battery manufacturing and PACK assembly, welding quality directly determines the safety and service life of the battery module. As a core equipment, precision resistance spot welding machine is reshaping the industry quality standards with its excellent process control capabilities and intelligent monitoring system.

Core equipment: precision resistance spot welding machine and resistance welding power supply

The equipment adopts high-precision current control technology, the welding power supply supports multi-stage pulse discharge, and the current output can achieve millisecond-level slow rise and fall. This flexible discharge mode not only greatly reduces the thermal shock of welding, but also accurately controls the process of molten core formation, making the surface of the weld smooth like a mirror, avoiding the spatter and cold welding problems common in traditional welding. According to actual measurements, its welding tensile strength is more than 30% higher than that of ordinary equipment, and the damage rate to the battery shell is reduced to less than 0.2%, which perfectly adapts to the strict requirements of the new energy industry for "zero defects".

The resistance welding monitor on the equipment is like a "welding quality inspector". Welding monitor can simultaneously collect 12 parameters such as welding current, voltage, time, etc., and analyze the welding quality in real time through AI algorithms. Once abnormal current, pressure fluctuation or material resistance change is detected, the system will automatically trigger a three-level protection mechanism: first early warning prompt, then adjust parameter compensation, and finally force shutdown to avoid batch defects. This full-process control of "prevention-correction-stop loss" directly reduces the welding defective rate to less than 0.5%, which is 80% lower than the industry average.

Technical breakthrough: dual guarantee of low heat generation and strong stability

By optimizing the power topology and heat dissipation design, the equipment generates 40% less heat than traditional models, and the consistency of solder joints is still as high as 99.6% after 8 hours of continuous work. Welding power supply original dynamic pressure compensation technology can automatically adapt to the thickness tolerance of the battery shell of 0.05mm to ensure the uniform and stable welding strength of each 18650 battery.

Today, as the new energy industry moves towards high-quality development, this resistance spot welding system that integrates precision control, intelligent monitoring, high efficiency and stability is becoming a core tool for battery manufacturers to break through production capacity bottlenecks and enhance product competitiveness.
