Features of laser welding machine 2000w

1. One machine has multiple functions, equipped with a multi-purpose nozzle to meet the functions of welding, cutting, cleaning and so on.

2. The independently developed handheld welding head is equipped with various safety alarm devices and is easy and flexible to operate.

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

4. The machine has multiple safety alarm functions. The trigger switch is only effective when the welding copper nozzle touches the metal and the safety clip clamps the metal plate. The welding copper nozzle will automatically lock after it is removed from the workpiece. The machine's high safety ensures the absolute safety of the operator during work.

5. Suntop’s patented water circulation protection system and auxiliary gas detection effectively extend the service life of the laser lens and prevent damage to optical components caused by improper operation.

6. Equipped with a high-precision wire feeder, touch capacitive screen, 220V drive, automatic wire feeding, more powerful wire feeding, and no wire jamming.

7. Comes standard with a variety of welding copper nozzles such as flat, inner corner, and outer corner. According to different welding needs, different nozzles can be replaced to meet various welding needs.

Advantages of laser welding machine 2000w

1. High energy density: Laser welding has a very high energy density, which means that energy can be quickly transferred to the material during the welding process, enabling fast and efficient welding.

2. High precision: Laser welding can align the weld seam very accurately and control the welding depth and width precisely, ensuring welding quality and precision.

3. Low heat input: Compared to traditional welding methods, laser welding has a lower heat input, which reduces the impact on surrounding materials during the welding process and minimizes deformation and stress.

4. High speed: Due to the high energy density and precise alignment of laser welding, high-speed welding can be achieved, improving production efficiency.

5. High quality: Laser welding produces very narrow weld seams, reducing the possibility of defects and porosity, improving the quality and strength of the weld.

6. Strong adaptability: Laser welding can be used for welding various metal materials and dissimilar materials.

7. Environmentally friendly: Laser welding does not require the use of any electrodes or tools to contact the material, so it does not produce pollution related to electric sparks or heat.

8. Automation capability: Laser welding can be automated, reducing errors caused by manual operation and improving production efficiency.

9. Material savings: Laser welding can achieve contactless processing, eliminating the need for electrodes or filler materials, thus saving costs.

10. Easy to control: Laser welding can be controlled through computer programs, enabling precise parameter control and complex welding trajectories.

Main uses of laser welding machine 2000w

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 width is small, the depth is large, the heat-affected zone is small, the deformation is small, the weld 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. Using a laser welding machine for cleaning has the characteristics of non-contact, no need for cleaning solution, and 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. The maximum cutting thickness is about 2mm.

4. Weld seam cleaning

In addition to the above three functions, our laser welding machine can also clean weld seams. Through laser cleaning, it 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.
