Lightweld 1500 Laser Welding System for Sale

The handheld laser welding machine is a new generation of laser welding equipment, which is non-contact welding and does not require pressure during the actual operation. Its basic working principle is to irradiate high-energy intensity laser beams directly on the surface of the material. The interaction between the laser and the material can melt the material internally, and then cool and crystallize to form a weld. Using optical fiber to transmit the laser and equipped with a handheld welding gun, it can weld in complex environments. Its advantages include stable output, high power, long service life, etc.

Features of lightweld 1500 laser welding system for sale

1. Verify the position of the welding head using infrared positioning to ensure the accuracy of the welding process. This results in a smoother and more aesthetically pleasing weld seam, which is easier to grind and polish. Additionally, it requires little to no treatment after welding.

2. The handheld welding head is self-developed and equipped with various safety alarm devices, making it easy and flexible to operate.

3. It is equipped with a high precision wire feeder, touch capacitive screen, 220V drive, and automatic wire feeding, ensuring a stronger and jam-free wire feeding process.

4. It is equipped with a 10m imported optical fiber, allowing for flexible and convenient outdoor and long-distance welding, overcoming the limitations of table space.

5. It is equipped with a double protection function (patented technology) for the water and gas circuit, effectively preventing damage to the laser lens or optical components caused by operator error. This significantly reduces the machine's failure rate and extends the lifespan of consumables.

6. The system can store various process parameters, allowing for easy switching through the touch screen based on processing needs. This reduces the time required for parameter debugging.

Advantages of lightweld 1500 laser welding system for sale

1. The welding speed is fast and the efficiency is high, which is 5-10 times that of traditional argon arc welding. This saves labor and reduces the processing cost by about 30%.

2. It has concentrated energy, a small heat-affected area, no deformation, no blackening, a large welding depth, firm welding, and fine and beautiful welds without bubbles. There is no need for grinding.

3. It has an interactive human-machine interface, making it easy to operate. There is no need for professional welders as ordinary people can easily master it in half an hour.

4. It has advantages such as high anti-reflection ability, high efficiency in thin plate welding, deep penetration in thick plate welding without spatter, maintenance-free operation, and a wide operation and frequency modulation range.

5. Safety is emphasized, as it does not have direct radiation and has low radiation levels. It does not harm the body and only requires protective glasses to filter strong light.

6. It is convenient and flexible to use, as the station can be adjusted at any time. There is no need for a fixed station, making it free and flexible. It is suitable for welding in various working environment scenarios.

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

Other optional functions

● Cleaning function

By replacing the laser nozzle and cleaning lens, the laser system can achieve a material surface cleaning function. This function effectively removes rust, oxide layers, oil stains, and other contaminants from the material surface without causing damage to its characteristics. It is a non-contact method that does not require the use of cleaning solutions, making it a suitable alternative to professional cleaning equipment.

● Cutting function

The laser system can perform simple cutting tasks. By simply changing the welding copper nozzle to the cutting copper nozzle, it allows for easy switching between welding and cutting operations. This feature provides great convenience.

The laser system is capable of cutting various metal sheets, including stainless steel, carbon steel, aluminum, aluminum alloy, and iron. It can cut materials with a maximum thickness of approximately 2mm.

● Welding seam cleaning function

The laser system effectively removes impurities such as oxides, welding slag, oil stains, and dust that are generated during the welding process. This results in a clean weld surface, which not only improves the quality of the weld but also enhances its strength and appearance. Laser cleaning offers high precision and controllability, allowing for thorough cleaning of the weld surface without causing any damage to the base material.
