60138 Supercapacitor Laser Welding Machine Solution

SPECIFICATIONS (Contact us for laser welder parameters and more details)

This TOB-LW-Series laser welding machine is suitable for the welding process of threaded terminal supercapacitor top current collector, bottom current collector, cap and filling port laser welding.

Principle of laser welding machine:

The work of laser welding machine is to apply high-energy pulse laser to achieve welding. The laser power supply firstly lights the pulse xenon lamp, and then discharge the lamp through the laser power supply to form a certain frequency and a certain pulse width light wave. The light wave radiates to the ND3+: YAG laser crystal through the concentrating cavity, and arouses ND3+: The YAG laser crystal emits light, then resonates through the laser resonator, and emits a pulse laser with a wavelength of 1064nm. The pulse laser is expanded, reflected, or focused by optical fiber transmission, and then hits the object to be welded.

In the welding field of lithium ion battery and supercapacitor, laser welding has great advantages over traditional welding technology, and is widely used in the welding of lithium ion battery.

Laser welding features:

1. High depth to width ratio, small welding width, small heat affected zone, small deformation, fast welding speed.

2. The welding seam is smooth and beautiful, without processing or simple processing process after welding.

3. Controllable, small focusing spot, high precision positioning, easy to realize automation.

4. Welding between different materials can be realized.

5. High quality welding seam, no porosity.
