Laser Welding Types

Laser welding technology is non-contact welding and does not require the application of pressure during the operation. It has the advantages of fast welding speed, high strength, large depth, small deformation, narrow weld seam, small heat affected zone, small workpiece deformation, less subsequent processing workload, less manual output, high flexibility and safety.

Features of laser welding types


1. Infrared positioning is utilized for calibrating and verifying the welding position in the welding process, resulting in increased accuracy and a more aesthetically pleasing welding seam.

2. The beam quality is excellent, allowing for precise control and creating fine weld joints. It has a small focusing spot, enabling high-precision positioning and facilitating automation.

3. The wire feeder features a high-precision touch capacitive screen, operates on 220V, and provides automatic wire feed. It offers a more powerful wire feed and prevents wire jamming.

4. Our self-developed handheld welding head is equipped with various safety alarm devices, ensuring easy and flexible operation.

5. We offer a range of welding copper nozzles to cater to different needs, including external welding, internal welding, right angle welding, narrow edge welding, and large spot welding. Customers can select the appropriate welding copper nozzle for their specific requirements.

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

Advantages of laser welding types


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

2. The weld seam is flat, beautiful, and free of pores, which reduces and optimizes base metal impurities. The structure can be refined after welding, and the strength and toughness of the weld seam are at least equal to or even exceed that of the base metal.

3. A wide range of welding materials allows for welding between dissimilar materials. It has a high depth-to-width ratio, small weld width, small heat-affected zone, small deformation, and requires less secondary processing.

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

5. The interactive human-machine interface makes it easy to operate, and no professional welders are needed. Ordinary people can easily master it in half an hour.

6. It has a high anti-reflection ability, high efficiency for thin plate welding, deep penetration of thick plate without spatter, requires no maintenance, and has a wide operation and frequency modulation range.

The main uses of handheld fiber laser welding machines


1. Welding

The main use of laser welding machine is undoubtedly welding. It can weld almost all metal materials and can complete welding well in various complex environments. It has high production efficiency and has more obvious advantages than traditional argon arc welding, electric welding and other processes. When welding, the production efficiency is high, which has more obvious advantages than traditional argon arc welding, electric welding and other processes.

Using a laser welding machine, the welding seam width is small, the depth is large, the thermal shock area is small, the deformation is small, the welding seam is smooth and beautiful, the welding quality is high, there are no pores, it can be precisely controlled, the welding quality is stable, and no processing or simple processing is required after welding.

2. Cleaning

With the continuous reform and upgrading of laser welding machines, they have more and more functions. They can not only weld and cut, but also clean and remove rust. The laser welding machine uses the beam emitted by the laser to eliminate the pollution layer on the surface of the workpiece being processed. Cleaning using a laser welding machine is non-contact and does not require cleaning fluid, so it can replace professional cleaning equipment.

3. Cutting

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

4. Weld seam cleaning

In addition to the above three functions, our laser welding machine can also clean the weld seam. Laser cleaning can effectively remove oxides, welding slag, oil, dust and other impurities produced during the welding process, making the weld surface clean. This not only helps improve the quality of the weld, but also enhances its strength and appearance. Laser cleaning is highly precise and controllable, thoroughly cleaning the weld surface without damaging the base material.
