Features of laser cold welding


1. Closed design, based on the principles of laser technology, self-designed for a more reasonable structure, dustproof, good heat dissipation, effectively extending the service life of machine components.

2. The independently developed handheld welding head is equipped with multiple safety alarm devices for convenient and flexible operation.

3. Equipped with a 10-meter original fiber optic cable, overcoming the limitations of workspace, enabling outdoor welding and long-distance welding cleaning.

4. The machine has multiple safety alarm functions. The welding nozzle switch is only effective when it touches the metal and securely clamps the metal sheet. The welding nozzle automatically locks the light after moving away from the workpiece. The machine has high safety to ensure absolute safety for operators during work.

5. Our machine has dual protection functions for water and gas circuits (patented technology), effectively avoiding damage to laser lenses or optical components caused by operator error, greatly reducing machine failure rate and extending the life of consumables.

Advantages of laser cold welding


1. High work efficiency: The laser focus spot is small, the power density is high, the welding speed is fast, the quality of the welded products is stable and reliable, and large-volume automated welding tasks can be realized.

2. Various welding methods: There are many welding methods used, such as spot welding, splice welding, butt welding, etc. Different welding can achieve different welding effects, and the appropriate welding method can be selected according to the properties, shape and other characteristics of the workpiece.

3. Good welding effect: Laser welding seams are small but have large depth, fast melting speed, small heat-affected zone, small deformation, and the welding workpiece is smooth and beautiful, which is more in line with the high-quality requirements of modern people.

4. Wide welding range: It can achieve precision welding of a variety of materials, especially for some materials that are difficult to weld, and can quickly melt different types of metal materials.

5. High flexibility: There is no limit on the position of the welding seam. It can access difficult-to-weld parts or local locations, and complete precise welding through precise positioning.

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


The main use of laser cold welding


1. Welding

The main purpose of the laser welding machine is undoubtedly welding, welding almost all metal materials, welding in a variety of complex environments can be well completed welding, high productivity, more obvious advantages than the traditional argon arc welding, electric welding and other processes. Welding, high productivity, more obvious advantages than the traditional argon arc welding, electric welding and other processes.

With the 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 flat and beautiful, the welding quality is high, no air holes, can be precisely controlled, the welding quality is stable, and there is no need to deal with it after welding or it can be simply dealt with.

2. Cleaning

With the continuous reform and replacement of the laser welding machine, more and more functions, not only welding and cutting, but also cleaning and rust removal, laser welding machine using the laser beam emitted, so that the surface of the workpiece to be processed by the elimination of the contamination layer. 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, the use of laser welding machine can cut stainless steel, carbon steel, aluminum, aluminum alloy, iron and other metal sheet, the maximum cutting thickness of about 2mm.

4. Welding seam cleaning

In addition to the above three functions, our laser welding machine can also clean the weld seam. Through laser cleaning, it can effectively remove oxides, welding slag, oil, dust and other impurities generated during the welding process, making the surface of the weld seam 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, allowing the weld surface to be thoroughly cleaned without damaging the base metal.
