Features of laser cutting and welding

1. Use infrared positioning for calibrating and verifying the welding position in the welding process. This will result in more accurate welding positions and more beautiful weld seams.

2. The machine is equipped with a high precision wire feeder that has a touch capacitive screen, a 220V drive, automatic wire feed, stronger wire feed, and no wire jam.

3. The handheld welding head is self-developed and is light and delicate, making it easy to operate and allowing for welding at any angle.

4. The machine is equipped with a 10m imported optical fiber, which overcomes the limitation of workbench space. This allows for flexible and convenient outdoor and long-distance welding.

5. The machine has multiple safety alarm functions. The welding copper nozzle is only effective when it touches the metal, and the safety clip clamps the metal plate when the trigger switch is effective. Additionally, the welding copper nozzle will automatically lock the light after moving away from the workpiece. This ensures high safety for the machine and guarantees the absolute safety of the operator during work.

6. The machine has a double protection function for the water and gas circuit (patented technology). This effectively prevents damage to the laser lens or optical components due to operator misoperation, reducing the failure rate of the machine and extending the life of consumables.

Details of laser cutting and welding

1. Laser welding head

The light weight is only 0.8KG, flexible and convenient to weld metal parts of any shape, the weld width is adjustable, and it can perform long-distance welding with a length of 10 meters. With security monitoring system.

2. Operation interface

Advanced resistive touch screen with higher sensitivity, intelligent control, can store multiple welding parameters, support multiple languages (English, Spanish, German, Italian, French, Russian, Turkish, etc.)

3. Automatic wire feeding system

Touch screen design, automatic wire filling, fully digital design, support 0.8mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm diameter stainless steel and aluminum wires.

4. Laser source

We use a customized 45um core diameter welding fiber laser with a lifespan of 100,000 hours, maintenance-free, and can weld various metals.

5. Water chiller

Double circulating water cooling makes the laser source and welding head cool better, and the temperature control sensor adopts imported brands.

6. Solder connection fiber

The 10-meter-long fiber optic cable, built-in design, effectively avoids the damage of the fiber and the problems caused by moisture, and greatly increases the life of the laser components.

Advantages of laser cutting and welding

1. The operation is flexible and simple, with no technical threshold requirements. Ordinary workers can be trained for a short period of time to be able to work, meeting the requirements for welding from multiple angles and positions.

2. The weld seam is smooth and beautiful, requiring no secondary grinding or minimal follow-up grinding after welding.

3. Various welding processes are available, such as spot welding, seam welding, lap welding, flat welding, inner corner welding, outer corner welding, ring welding, and top welding.

4. The workstation can be adjusted at any time, without the need for a fixed workstation, allowing for freedom and flexibility, suitable for welding in various work environments.

5. Low usage cost, with low consumption of electricity, gas, and lenses.

6. The affected area of the welding is small, causing no deformation or blackening, with a large welding depth, strong welding, and sufficient melting.

Uses of laser cutting and welding

With the continuous development of laser welding technology, the use of laser welding machine is more and more extensive.

● Welding: laser welding machine main welding object for the metal, such as stainless steel, copper, aluminum, gold, silver, titanium, nickel, tin, chromium, niobium, carbon steel, mold steel, galvanized plate, etc., applicable to the plane, straight line, arc, and any shape of the weld, multi-angle to carry out the welding work to meet the user's individualized welding needs.

● Cutting: welding and cutting are often inseparable, laser welding machine combines the functions of the two together, laser welding machine can be used for laser cutting of metal materials, such as copper, aluminum, stainless steel, carbon steel, galvanized plate, etc., to meet the conventional thin plate type of cutting needs.

● Cleaning: the use of laser welding machine for cleaning easy to use and flexible, able to remove all types of workpiece surface rust, oxides and grease and dirt, etc., in the use of handheld laser welding machine for cleaning, the need to avoid the laser beam irradiation to the human body causing injury.

● Weld channel cleaning: can effectively remove the welding process generated by the oxides, welding slag, oil, dust and other impurities, so that the weld surface becomes 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.
