Features of Laser manual welding


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

2. It is equipped with 10m of imported optical fiber, which allows for flexibility and convenience in outdoor and long-distance welding.

3. Suntop's patented technology includes a water circulation protection system and auxiliary gas detection. These effectively prolong the life of the laser lens and prevent damage to optical components caused by improper operation.

4. The hand-held torch is lightweight and delicate, making it easy to operate and enabling welding at any angle.

5. It comes standard with a variety of welding copper nozzles, such as flat, inside, and outside corners. Different nozzles can be replaced to meet various welding needs.

6. It can achieve welding at any angle, 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 workpieces, including larger workpieces with irregular shapes.

2. Operation interface

Multi-language intelligent control panel, flexible adjustment of welding parameters, multi-group welding parameter library, light output cumulative timing, 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 wire.

4. Laser Source

We use customized minimum 20um core diameter fiber for deeper penetration, laser life up to 100,000 hours, maintenance-free, with Bluetooth capability.

5. Water Chiller

Double cycle water cooling makes the laser source and welding head cooling better, temperature control sensor adopts imported brand.

6. Welding connection fiber optic

10 meters long fiber optic cable with built-in design effectively avoids damage to the fiber and problems caused by moisture, which greatly increases the service life of the laser components.

Advantages of Laser manual welding


1. High energy density: the energy density of laser welding is very high, which means that the energy can be quickly transferred to the material during the welding process, thus realizing fast and efficient welding.
2. High precision: laser welding can be very precisely aligned to the weld seam, and can accurately control the welding depth and width, thus ensuring welding quality and precision.
3. Low Heat Input: Compared with traditional welding methods, laser welding has a low heat input, which reduces the impact on the surrounding material during the welding process and reduces distortion and stress.
4. High speed: Due to the high energy density and precise alignment of laser welding, high speed welding can be realized, thus increasing productivity.
5. High quality: laser welding produces very narrow weld seams, which reduces the possibility of defects and porosity and improves the quality and strength of the weld.
6. High adaptability: laser welding can be adapted to a variety of metal materials and dissimilar materials.
7. Environmentally friendly: the laser welding process does not require the use of any electrodes or tools to contact the material, so there is no pollution related to electric sparks or heat.
8. Can be automated: laser welding can be automated, reducing errors and improving productivity brought about by manual operation.
9. Saving material: Laser welding can realize non-contact processing without the use of electrodes or filler materials, thus saving costs.
10. Easy to control: laser welding can be controlled by computer program to achieve precise parameter control and complex welding trajectory.

Other optional functions of Laser manual welding

Cutting

Welding and cutting often go hand in hand, and the laser welding machine combines the functions of both. It can be used for laser cutting of metal materials, including copper, aluminum, stainless steel, carbon steel, galvanized plate, etc., to meet the cutting needs of conventional thin plates.

Cleaning

The laser welding machine is easy to use and flexible for cleaning purposes. It can effectively remove various types of surface rust, oxides, grease, dirt, etc. However, when using a handheld laser welding machine for cleaning, it is important to avoid the laser beam causing injury to the human body.

Weld channel cleaning

This process effectively removes impurities such as oxides, welding slag, oil, and dust generated during the welding process, resulting in a clean weld surface. This not only improves the quality of the weld but also enhances its strength and appearance. Laser cleaning is highly accurate and controllable, allowing for thorough cleaning of the weld surface without damaging the base metal.
