Laser Welding Machine

Email: imani@batterypackassembly.com

Product introduction:

Laser welding is widely used in the sealing welding of stainless steel shell and aluminum shell in lithium battery manufacturing. Due to the use of optical fiber transmission, the laser welding is more suitable for matching with the flow production line and realizing welding automation. At the same time, the welding performance and appearance have been significantly improved.

Principle:

The work of laser welding machine is to use high energy pulse laser to realize welding. Firstly, the pulsed xenon lamp is ignited by the laser power supply, and then the xenon lamp is discharged by the laser power supply to form a light wave with a certain frequency and a certain pulse width. The light wave is radiated to the Nd3 +: YAG laser crystal through the concentrating cavity, which excites the Nd3 +: YAG laser crystal to emit light. After the laser resonance cavity resonates, the emission wavelength is 1064nm Pulse laser, the pulse laser after beam expansion, reflection, (or transmission through optical fiber) focus on the object to be welded;

Under the control of PLC or industrial PC, the NC worktable is moved to complete welding. The frequency, pulse width, duty cycle, speed of worktable and moving direction of pulse laser needed in welding can be used by single chip microcomputer, PLC or industry

The energy of pulse laser can be adjusted and controlled by different setting of laser frequency and pulse width.

Main features:

Laser welding is a new welding method. Laser welding is mainly aimed at the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, overlap welding, sealing welding, etc

*It has high aspect ratio, small weld width, small heat affected zone, small deformation and fast welding speed.

*The welding seam is smooth and beautiful, and there is no need to deal with or only need simple processing procedure after welding.

*The welding seam has high quality and no blowhole, which can reduce and optimize the impurities in the base metal. The microstructure can be refined after welding. The strength and toughness of the weld are at least equal to or even higher than that of the base metal.

*It can be controlled accurately, focus light spot is small, high precision positioning, easy to realize automation.

*It can realize the welding between some dissimilar materials.

Weldable materials and industry applications:

Laser welding can be applied to the welding of titanium, nickel, tin, zinc, copper, aluminum, chromium, niobium, gold, silver and other metals and their alloys, steel, kovar alloy and other alloys. It can also be applied to the welding of copper nickel, nickel titanium, copper titanium, titanium molybdenum, brass copper, low carbon steel copper and other dissimilar metals.

It is widely used in mobile communication, electronic components, glasses, watches, jewelry accessories, hardware products, precision equipment, medical equipment, auto parts, craft gifts and other industries.
