Features of 4-in-1 handheld metal laser welding machine

1. One machine with four functions: rapid switching between four modes: cleaning, welding, cutting and weld cleaning.

2. The handheld welding gun replaces the previous fixed light path, which is more flexible and convenient, enables long-distance laser welding, and overcomes the limitations of the workbench travel space.

3. The handheld welding head is light and flexible, easy to operate, and can meet welding at various angles and positions.

4. Use infrared positioning for welding head position calibration and position verification during welding to ensure a more beautiful weld.

5. 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 due to operator misoperation, thus greatly reducing the machine failure rate and effectively extending the service life of the machine. The life of consumables.

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.

Advantages of 4-in-1 handheld metal laser welding machine

1. Simple, easy to learn, flexible and convenient

Adopting an integrated structure, the requirements for operators are not high, and they can be put on the job after simple training. The operation is simple and quick to get started; multi-dimensional welding is flexible and convenient.

2. Low investment and maintenance costs

Handheld laser welding does not require a precision welding station, requires less consumables, has low equipment deployment and maintenance costs, and is highly cost-effective.

3. Save labor

Handheld laser welding is fast, 5-10 times faster than traditional welding. One machine can save at least 2 welders a year; the welded seam after welding is smooth and beautiful, reducing subsequent polishing processes, saving time and costs.

4.Good quality

The laser welded workpiece has no deformation, no welding scars, and the welding is firm.

5. Security protection

It has a contact safety protection function to avoid accidental light emission and ensure that the light can be welded only after contact with metal. Equipped with laser protective glasses, which need to be worn when welding. To ensure safety.

Remark: Double weld thickness can be achieved if the material is welded from both sides in two times.

The main uses of laser welding machines

1. Welding

The main use of laser welding machine is undoubtedly welding. It can not only weld stainless steel plates, aluminum plates, galvanized plates and other thin-walled metal materials, but also can be used for welding sheet metal parts, such as kitchen utensils. It is suitable for planes, straight lines, arcs and Welding of arbitrary shapes is widely used in precision machinery, jewelry, electronic components, batteries, watches, communications, handicrafts and other industries. It can complete welding well in various complex environments and has high production efficiency. It is better than traditional argon arc welding and electric welding. and other processes have more obvious advantages.

Using a laser welding machine, the welding seam width is small, the depth is large, the thermal shock area is small, the deformation is small, the welding seam is smooth and beautiful, the welding quality is high, there are no pores, it can be accurately controlled, the welding quality is stable, and no processing or simple processing is required after welding.

2. Cleaning

As laser welding machines continue to be reformed and updated, they have more and more functions. They can not only weld and cut, but also clean and remove rust. Laser welding machines use the beam emitted by the laser to remove the contamination layer on the surface of the workpiece being processed. Cleaning using a laser welding machine is non-contact and does not require cleaning fluid, and can replace professional cleaning equipment.

3. Cutting

Laser cutting is a new cutting method. The laser welding machine can be used to cut stainless steel, carbon steel, aluminum, aluminum alloy, iron and other thin metal plates. The maximum cutting thickness is about 2mm.

4. Weld cleaning

In addition to the above three functions, our 3000W handheld laser welding machine can also clean the weld seam. Laser cleaning can effectively remove oxides, welding slag, oil, dust and other impurities generated during the welding process, making the weld surface clean. This not only helps improve the quality of the weld, but also enhances the strength and appearance of the weld. Laser cleaning is highly precise and controllable, and can thoroughly clean the weld surface without damaging the base material.
