Features of metal laser welding machine

1. The handheld welding head, which has been developed in-house, is equipped with various safety alarm devices to allow for more flexible and convenient operation. It overcomes the limitations of table travel space and can be used for welding at various angles and positions.

2. In the welding process, infrared positioning is used for welding position calibration and verification. This ensures more accurate welding positions and results in more beautiful weld seams.

3. It is equipped with a 10m imported optical fiber, which allows for flexible and convenient outdoor and long-distance welding.

4. The welding is smooth and beautiful, with no deformation, eliminating the need for secondary grinding. This solves the problems of weld penetration, weld tumor, and welding quality that often occur when using argon arc welding.

5. It is equipped with a high-precision touch capacitive screen wire feeder, with a 220V drive and automatic wire feed. This provides a more powerful wire feed and eliminates the problem of wire jamming.

6. Suntop's patented technology includes a water circulation protection system and auxiliary gas detection, which effectively extends the life of the laser lens and prevents damage to optical components caused by improper operation.

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 metal laser welding machine

1. The machine parts have an ergonomic design, a more reasonable structure, and are dustproof, with good heat dissipation. This effectively extends the service life of the machine parts.

2. The weld seam is flat and beautiful, without any porosity. This reduces and optimizes the base material magazine, and the organization can be refined after welding. The strength and toughness of the weld seam are at least equal to, or even exceed, the base metal.

3. The welding speed is fast, being 5-10 times faster than traditional argon arc welding. This can reduce processing costs by about 30%.

4. The human-machine interface is interactive and easy to operate. Professional welders are not required, as ordinary people can easily master it in half an hour.

5. It has a high anti-reverse capability and is highly efficient for thin plate welding. There is no spatter for thick plate deep melting. It is maintenance-free and has a wide range of operation and frequency regulation.

6. It offers various welding methods, allowing for any angle welding, stack welding, butt welding, vertical welding, flat angle welding, internal angle welding, external angle welding, etc. It can be used to weld a variety of complex welding seams on the workpiece, including larger workpieces with non-regular shapes.

Main uses of laser welding machine

1. Welding

The main use of laser welding machines is undoubtedly welding. They can be used to weld thin-walled metal materials such as stainless steel plates, aluminum plates, galvanized plates, as well as sheet metal parts welding, such as kitchen utensils. They are suitable for welding flat surfaces, straight lines, curves, and any shape. They are widely used in precision machinery, jewelry, electronic components, batteries, clocks, communications, crafts, and other industries. They can achieve good welding results in various complex environments, with high production efficiency and more significant advantages compared to traditional processes such as argon arc welding and electric welding. Laser welding machines have small weld width, large depth, small heat-affected area, minimal deformation, smooth and beautiful welds, high welding quality, no pores, accurate control, stable welding quality, and no need for post-weld treatment or simple treatment.

2. Cleaning

With the continuous reform and upgrading of laser welding machines, they have more and more functions. In addition to welding and cutting, they can also be used for cleaning and rust removal. Laser welding machines use the laser beam emitted by the laser to remove the contamination layer on the surface of the processed workpiece. Using a laser welding machine for cleaning has the characteristics of non-contact and does not require cleaning solution, which can replace professional cleaning equipment.

3. Cutting

Laser cutting is a new cutting method. Laser welding machines can be used to cut thin metal sheets such as stainless steel, carbon steel, aluminum, aluminum alloy, and iron. The maximum cutting thickness is about 2mm.

4. Weld seam cleaning

In addition to the above three functions, our 3000W handheld laser welding machine can also clean weld seams. Laser cleaning can effectively remove impurities such as oxides, welding slag, oil stains, and dust generated during the welding process, making the weld seam surface 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.
