Laser Welding with Filler Wire

Laser welding is the use of high-energy laser pulses to locally heat materials in a small area. The energy from the laser radiation diffuses into the material through thermal conduction, melting the material and forming a specific molten pool. Laser welding is fast, with efficiency several times higher than traditional welding equipment. It is not limited by space and can automatically feed wire, requiring less welding material. The energy generated during welding is concentrated and precise, with a small heat-affected zone. It does not cause deformation or blackening, and the weld seam is full and aesthetically pleasing, requiring no polishing. Additionally, laser welding has a large welding depth and high strength.

Features of laser welding with filler wire


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, making it 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, allowing for easy and flexible operation.

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. The machine 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 has the capability to store various process parameters, allowing for easy switching through the touch screen based on processing needs. This reduces the time required for parameter debugging.

1. Laser welding head

Lightweight at only 0.8KG, it is flexible and convenient for welding metal parts of any shape. The weld width is adjustable and can be used for welding at a distance of up to 10 meters. Equipped with a safety temperature monitoring system.

2. Operation interface

Multilingual intelligent control panel, flexible adjustment of welding parameters, multiple sets of welding parameter libraries, cumulative timing of light output, etc.

3. Automatic wire feeding system

Touch screen design, automatic wire filling, fully digital design, supports stainless steel and aluminum wires with diameters of 0.8mm, 1.0mm, 1.2mm, 1.6mm, and 2.0mm.

4. Laser source

We use custom optical fibers with a minimum core diameter of 20um, which allows for deeper penetration and a laser lifespan of up to 100,000 hours. It is maintenance-free and has Bluetooth functionality.

5. Water cooler

Dual circulation water cooling system for cooling the laser source and welding head, with temperature control sensors from imported brands.

6. Welding connection fiber

Built-in design within a 10-meter long cable, effectively avoiding problems caused by fiber damage and moisture, greatly improving the lifespan of the laser device.

Advantages of laser welding with filler wire


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, fine and beautiful welds without bubbles, and 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 several advantages, including 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.

The uses of laser welding machines


With the continuous development of laser welding technology, the uses of laser welding machines are becoming more and more extensive.


1. Welding: Laser welding machines are mainly used for welding metals, such as stainless steel, copper, aluminum, gold, silver, titanium, nickel, tin, chromium, niobium, carbon steel, mold steel, galvanized sheet, etc. They are suitable for welding flat, straight, curved, and any shape, and can perform welding work at multiple angles to meet the personalized welding needs of users.

2. Cutting: Welding and cutting often go hand in hand, and laser welding machines combine the functions of both. Laser welding machines can be used for laser cutting of metal materials, such as copper plates, aluminum plates, stainless steel plates, carbon steel plates, galvanized sheets, etc., to meet the cutting needs of conventional thin plates.

3. Cleaning: Using a laser welding machine for cleaning is convenient and flexible. It can remove rust, oxides, and oil stains from various workpiece surfaces. When using a handheld laser welding machine for cleaning, it is necessary to avoid the laser beam shining on the human body to prevent injury.

4. Weld seam cleaning: It can effectively remove impurities such as oxides, welding slag, oil stains, and dust generated during the welding process, making the surface of the weld seam clean. This not only helps improve the quality of the weld seam but also enhances its strength and appearance. Laser cleaning has high precision and controllability, and can thoroughly clean the surface of the weld seam without damaging the base material.
