Advantages of hg500 tm 4 in 1 handheld metal laser welding machine

1. Simple, easy to learn, flexible, convenient

Adopting an integrated structure, it does not require high demands on operators. Simple training is sufficient to start the job, with easy and quick operation. It offers multi-dimensional welding, providing flexibility and convenience.

2. Low investment and maintenance costs

Handheld laser welding requires no fine welding table, consumes less consumables, and has low equipment deployment and maintenance costs, offering high cost-effectiveness.

3. Labor-saving

Handheld laser welding is fast, 5-10 times faster than traditional welding, and one machine can save at least 2 welders per year. The welded seams are smooth and beautiful, reducing subsequent polishing processes, saving time and costs.

4. Good quality

Laser-welded workpieces have no deformation or welding scars, ensuring strong and secure welding.

5. Safety protection

It has contact-type safety protection function to avoid accidental emission of light, ensuring that the light is emitted for welding only when in contact with metal. Laser protective glasses are provided and must be worn during welding to ensure safety.

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

The main use of laser welding machine

1. Welding

The main purpose of the laser welding machine is undoubtedly welding, not only can weld stainless steel plate, aluminum plate, galvanized plate and other thin-walled metal materials, but also can be used for sheet metal welding, such as kitchen utensils, applicable to its plane, straight line, arc and any shape of the weld, is widely used in precision machinery, jewelry, electronic components, batteries, clocks and watches, communications, handicrafts, and other industries in a variety of complex environments can be a good completion of welding, high production efficiency, more obvious advantages than traditional tig welding, electric welding and other processes. Welding, high productivity, than the traditional argon arc welding, welding and other processes have more obvious advantages.

Using laser welding machine, the weld width is small, the depth is large, the thermal shock area is small, the deformation is small, the weld is smooth and beautiful, the welding quality is high, no porosity, can be accurately controlled, the welding quality is stable, no need to deal with the welding after welding or simple treatment can be.

2. Cleaning

As the laser welding machine continues to reform and change the generation, the function is more and more, not only can welding and cutting, but also cleaning and rust removal, laser welding machine using the beam emitted by the laser, so that the contamination layer on the surface of the workpiece to be dealt with is eliminated. The use of laser welding machine for cleaning, with no contact characteristics, do not need cleaning fluid, can replace the professional cleaning equipment.

3. Cutting

Laser cutting is a new type of cutting method, the use of 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 of about 2mm.

4. Welding seam cleaning

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