Features of laser welding machine for lithium ion batteries


1. It adopts a fully enclosed optical path design, with advantages such as dustproof and good sealing; it can work continuously for a long time (up to 24 hours).

2. The self-developed Wobble welding head is small, lightweight, and easy to operate.

3. It has multiple safety alarm functions. The switch is only activated when the welding copper head contacts the metal, and the safety clamp clamps the metal plate. After removing the welding copper nozzle from the workpiece, the light will automatically lock. The machine has a very high level of safety, ensuring absolute safety for operators during work.

4. It uses infrared positioning to verify the position of the welding head during the welding process. The welding position is more accurate, the weld is smooth and beautiful, easy to polish, and no post-welding treatment is required or only simple treatment is needed.

5. It is equipped with various nozzles for multiple functions such as welding, cutting, and cleaning.

Advantages of laser welding machine for lithium ion batteries


1. High work efficiency: Laser has a small focus spot, high power density, fast welding speed, and stable and reliable product quality, which can achieve large-scale automated welding tasks.

2. Various welding methods: such as spot welding, seam welding, butt welding, etc. Different welding methods can achieve different welding effects, and suitable welding methods can be selected according to the characteristics of the workpiece, such as its nature and shape.

3. Good welding effect: Laser welding has small but deep welds, fast melting speed, small heat-affected zone, and low deformation. The welded workpiece is smooth and beautiful, which meets the high-quality requirements of modern people.

4. Wide welding range: Laser welding machines can achieve precision welding of various materials, especially for some difficult-to-weld materials. They can quickly melt different types of metal materials. They can not only weld precision components but also weld large and irregular workpieces to meet different welding needs.

5. Great flexibility: There is no restriction on the position of the weld, and it can reach difficult-to-weld parts or local positions. Precise welding can be achieved through accurate positioning.

6. Long service life: The machine has low operating costs and a long service life of up to 100,000 hours. It is maintenance-free, installation-free, and training-free. It is a very practical welding equipment.

The main use of handheld fiber laser welding machine


1. Welding

The main purpose of a laser welding machine is undoubtedly welding. It can weld almost all metal materials and can perform welding in various complex environments. It has high production efficiency and has more advantages compared to traditional processes such as argon arc welding and electric welding. When welding, it has higher production efficiency and more obvious advantages compared to traditional processes such as argon arc welding and electric welding. Using a laser welding machine, the weld seam width is small, the depth is large, the heat-affected zone is small, the deformation is small, the weld seam is smooth and beautiful, the welding quality is high, there are no pores, it can be precisely controlled, the welding quality is stable, and no post-weld treatment or simple treatment is required.

2. Cleaning

With the continuous reform and upgrading of laser welding machines, they have more and more functions. They can not only weld and cut, but also clean and remove rust. Laser welding machines use laser beams to eliminate the contamination layer on the surface of the processed workpiece. Cleaning with a laser welding machine has the advantage of being non-contact and does not require cleaning fluid, which can replace professional cleaning equipment.

3. Cutting

Laser cutting is a new type of cutting method. Using a laser welding machine, it can cut stainless steel, carbon steel, aluminum, aluminum alloy, iron, and other metal sheets, with a maximum cutting thickness of about 2mm.

4. Weld seam cleaning

In addition to the above three functions, our laser welding machine can also clean weld seams. Laser cleaning can effectively remove impurities such as oxides, welding slag, oil stains, and dust generated during the welding process, making the weld seam surface clean. This not only helps improve the quality of the weld seam but also enhances its strength and appearance. Laser cleaning has high precision and controllability, and can thoroughly clean the surface of the weld seam without damaging the base material.
