Features of 4 in 1 handheld laser welding machine
1. Closed design, self-designed based on laser principles, with a more reasonable structure, dustproof, good heat dissipation, effectively extending the service life of machine components.
2. Can be used for cleaning the surface of workpieces. By adjusting the parameters of the laser beam, it can remove dirt, oxide layers, etc. from the surface of the workpiece, restoring its original smoothness and brightness.
3. Equipped with a 10-meter original fiber optic cable, overcoming the limitations of workspace, enabling outdoor welding cleaning and long-distance welding cleaning.
4. The machine has multiple safety alarm functions. The welding copper nozzle switch is only effective when it touches the metal and securely clamps the metal sheet. The welding copper nozzle automatically locks the light after moving away from the workpiece. The machine has high safety, ensuring absolute safety for operators during work.
5. Our machine has dual protection functions for water and gas circuits (patented technology), effectively avoiding damage to laser lenses or optical components caused by operator errors, greatly reducing the failure rate of the machine and effectively extending the life of consumables.

Advantages of 4 in 1 handheld laser welding machine
1. High precision and high quality
Handheld laser welding equipment has the characteristics of high precision and high quality. Due to the high focus of the laser beam, the welding process has high energy density, resulting in a small heat-affected zone and good welding quality. At the same time, the welding accuracy of handheld laser welding equipment can reach about 0.2mm.
2. Fast welding speed
Compared to traditional welding methods, handheld laser welding equipment has a very fast welding speed, mainly due to the high power of the laser beam. During the welding process, the laser beam can quickly scan the weld seam and complete the welding task rapidly. This undoubtedly improves production efficiency and reduces production costs.
3. Not limited by materials
It can weld almost all metal materials, including stainless steel, carbon steel, aluminum alloy, etc. Therefore, it can meet a wide range of application needs.
4. Not limited by space
The laser welding machine and welding gun are integrated together, and the handheld laser welding equipment can be conveniently moved to perform various welding tasks, whether indoors or outdoors, whether on flat or curved surfaces.
5. Easy operation
The operation is simple and easy to learn, with no technical threshold for operators. Ordinary workers can start operating after a short training, and can easily achieve high-quality welding results. Laser welding does not require secondary polishing, saving a lot of labor costs.
Single side weld thickness

Stainless steel (mm) | 0.5-4 | 0.5-5/6 | 0.5-6/7 |
Mild steel (mm) | 0.5-4 | 0.5-6 | 0.5-7/8 |
Aluminum (mm) | 0.5-3 | 0.5-4 | 0.5-5 |
Brass/copper (mm) | 0.5-2 | 0.5-2.5 | 0.5-3 |
Galvanized sheet (mm) | 0.5-4 | 0.5-5/6 | 0.5-6/7 |
Iron (mm) | 0.5-4 | 0.5-6 | 0.5-7/8 |
Remark: Double weld thickness can be achieved if the material is welded from both sides in two times.
Other optional features
● Cleaning
With the continuous reform and upgrading of laser welding machines, their functions are becoming more and more diverse. They can not only weld and cut, but also clean and remove rust. Laser welding machines use laser beams emitted by lasers to remove the contamination layer on the surface of the processed workpiece. Using laser welding machines for cleaning has the advantage of being non-contact and does not require cleaning fluid, which can replace professional cleaning equipment.
● 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.
● Weld seam cleaning
It can also clean weld seams. Through laser cleaning, it 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 the strength and appearance of the weld seam. Laser cleaning has high precision and controllability, and can thoroughly clean the surface of the weld seam without damaging the base material.
Welding method
There are various welding methods to choose from, allowing for welding at any angle, including overlay welding, butt welding, vertical welding, fillet welding, inside corner welding, outside corner welding, etc. These methods can be used for welding various workpieces, including complex welds and irregularly shaped workpieces, especially larger ones.
