Optical Fiber Laser Welding Machine

Laser beam is used for welding. The diameter of the laser beam is very small and high-precision welding can be achieved. Compared with traditional welding methods, the welding seams of handheld laser welding machines are smaller and the welding effect is more beautiful. At the same time, there is no need to contact the welding material during the laser welding process, which reduces damage to the welding material and improves the welding quality.

Features of optical fiber laser welding machine


1. Four functions in one machine: quick switching between cleaning, welding, cutting and weld cleaning modes.

2. Integrated design, reasonable structure, dustproof, good heat dissipation, effectively extending the service life of machine parts.

3. The independently developed swing welding head is small, lightweight, easy to operate and flexible.

4. It has the dual protection function of water path and air path (patented technology), which effectively avoids damage to the laser lens or optical components caused by operator misoperation, thus greatly reducing the machine failure rate and effectively extending the machine's service life. The life of consumables.

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

6. Use infrared positioning to verify the position of the welding head during the welding process. The welding position is more accurate, the welding seam is smooth and beautiful, and it is easy to grind and polish. No post-welding treatment is required or only simple processing is required.

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.
