Through fast laser technology new breakthrough 3 kW green laser boost lithium battery industry

Shenzhen March 23, 2021 / US Department / – At the 14th China International Battery Technology Exhibition held last week, the leader in the high-end equipment field in the world’s high-end equipment is started. A 3 kW high-power continuous green disc laser TRUDisk 3022. The average output power of this product is as high as 3 kW, which represents the most powerful power in the green laser series, which is very suitable for welding of high against materials such as copper and aluminum. In particular, in the lithium-industrial industry represented by the new energy vehicle power battery, the high-speed green laser can achieve up to 120 layers of copper foil welding, almost no splash, and the depth is accurately controllable.

[123 Due to the superior conductivity of the copper material, the lithium industry, especially the new energy vehicle power battery, using copper materials. However, the absorption rate of copper on the laser is very different from different wavelengths: at room temperature, copper is less than 5 percentage of infrared wavelength (about 1000 nm) absorption, with infrared light to process the copper product is extremely low, 95% The laser is reflected and damaged the laser itself; the copper is high as the green wavelength (515 nm) absorption rate up to 40%, so the welding efficiency of copper with green light is very high, and there is almost no splash. It must be stated that splash is fatal, and spatter will affect the production safety, performance and life of the battery.

Tacble based on its own disc laser technology, the first release of 1 kW high-brightness continuous green laser Trudisk 1020 in 2015, and raised laser power to 3 kW in last year. Using TRUDISK3022, you can also match BRIGHTLINE WELD, reducing post-processing, reducing machine downtime and operating costs.

At present, the global installed capacity of the fast disc laser has exceeded 20,000, and its reliability, stability, and industrial utility have been fully verified. In addition to the laser source, it is also a one-stop solution for users to include machining heads, scanning gamuses, fiber, visual positioning, weld tracking, etc., and process development.
