From the manufacture of the lithium-ion battery cell to the battery pack, the welding is a very tight manufacturing process, the conductivity, strength, airtightness, metal fatigue and corrosion resistance of the lithium ion battery are typical battery welding quality. evaluation standard. Welding approach and welding process, the conformance of the cost, quality, safety, and lithium-ion battery will be directly affected by the cost, quality, safety, and lithium-ion battery of the lithium-ion battery.
In many welding methods, the lithium-ion battery produced laser welding results in the following advantages: First, the laser welding energy is high, the welding is small, the heat affected zone is small, and the material can be effectively improved, the weld is smooth, there is no impurities, and the average dense No additional grinding work; secondly, laser welding can accurately control, focus light, high-precision positioning, mating mechanical arm is easy to achieve automation, improve welding efficiency, reduce working hours, reduce costs; additional, laser welding thin plate or fine diameter When the wire is wire, it is not easy to be fused as the arc welding. The advantage of laser welding has a wide range of materials that can be welded and can achieve welding between different materials. During the welding process of the power lithium-ion battery, the welding process technician will set reasonable depending on the battery material, shape, thickness, tension requirements, etc.
, including welding speed, waveform, peak, welding head tilt angle, etc. Welding process parameters to ensure that the final welding effect meets the requirements of the power lithium-ion battery manufacturer. .
