This 6000W high-power handheld fiber laser welding machine is specifically designed for welding thick metal plates in the industrial sector. With ample output power, it can efficiently weld thick plates such as carbon steel, stainless steel, and aluminum alloys, producing deep weld penetration and smooth weld formation, reducing subsequent grinding processes. The handheld operation allows for flexible operation and adaptability to various workpieces, pipes, and irregularly shaped parts, meeting the high-intensity production needs of steel structures, heavy equipment, and metal processing plants.


The machine is equipped with a mature fiber laser generation system, ensuring strong welding stability, excellent performance against highly reflective materials, and minimal thermal deformation, reducing the likelihood of incomplete welds or missed welds. It has a low operating threshold and is easy to debug; workers can operate it quickly after simple training, effectively improving workshop processing efficiency and reducing reliance on manual welding techniques.


The equipment is suitable for continuous, long-term industrial operation. Its robust and durable structure facilitates easy maintenance, making it ideal for high-volume, high-intensity metal welding applications. It represents a cost-effective welding solution for heavy metal processing projects.


True 5-in-1 Function






● Welding

Laser welding features fast speed, narrow weld seam, low thermal impact and minimal deformation. It delivers smooth, pore‑free, high‑quality welds with precise and stable control, requiring little or no post‑weld treatment. Supporting multi‑angle welding for planes, curves and complex‑shaped workpieces, it performs well in diverse working conditions and boasts higher efficiency compared with traditional argon arc welding and electric welding.

● Cleaning

By changing the laser nozzle and cleaning lens, the machine achieves material surface cleaning. It efficiently removes rust, oxide layers and oil stains without damaging substrate surfaces. This non‑contact cleaning needs no cleaning agents and can substitute dedicated cleaning equipment.

● Cutting

Equipped with switchable welding and cutting functions, the machine supports easy mode conversion simply by replacing the copper nozzle. It can cut common metal sheets including carbon steel, stainless steel, iron and aluminum alloy, with a maximum cutting thickness of 2 mm.

● Weld cleaning

It effectively clears welding‑generated oxides, slag, oil and dust for clean weld surfaces, improving weld quality, strength and appearance. With high precision and controllability, laser cleaning thoroughly treats welds without damaging base materials.



Energy Storage Welding

It copes well with high‑energy‑demand welding tasks to guarantee consistent welding quality. Delivering massive energy in a short time, energy‑storage welding fits diverse metals, especially for high‑strength and precision welding scenarios.

Product Technical Features

1. One machine with four functions: rapid switching between four modes: Energy storage welding, cleaning, welding, cutting and weld cleaning.

2. The handheld welding gun replaces the previous fixed light path, which is more flexible and convenient, enables long-distance laser welding, and overcomes the limitations of the workbench travel space.

3. The handheld welding head is light and flexible, easy to operate, and can meet welding at various angles and positions.

4. Use infrared positioning for welding head position calibration and position verification during welding to ensure a more beautiful weld.

5. It has the dual protection function of water path and air path (patented technology), which effectively avoids damage to the laser lens or optical components due to operator misoperation, thus greatly reducing the machine failure rate and effectively extending the service life of the machine. The life of consumables.

6. Use infrared positioning to verify the position of the welding head during the welding process. The welding position is more accurate, the welding seam is smooth and beautiful, and it is easy to grind and polish. No post-welding treatment is required or only simple processing is required.

7. Suntop Laser Cleaning Machine is subjected to strict tests and continuous 24-hour laser beam output before leaving our factory to ensure 100% machine stability.
