Output power: 3800 W
Welding depth: up to 40 mm (depending on the material)
Modes: Welding / Cutting / Cleaning / Rust Removal
Compatible materials: stainless steel, aluminum, copper, carbon steel.

Why use laser welding?
The penetration depth of 3.8 kW is 10-40 mm.
Get good results without wire feeding.
It's easier to achieve good results even without a certified welder.


Thanks to the extremely high intensity of our 3800 W laser, the joined area of the pieces reaches vaporization temperatures, resulting in deep welds.


Laser welding, cutting, weld cleaning, and pickling can be performed simultaneously.
Power up to 3800W

There's no need to purchase additional equipment for these diverse jobs; all you need is one of BET's innovative 4-in-1 laser welders. It can weld, clean, cut, and remove rust, all at the same time.

The speed of our laser welding

Higher speeds mean more efficient welding and lower labor costs!
In the past, laser welders were widely used for welding stainless steel, carbon steel, and aluminum alloys.
A new application for laser welding machines will now be copper welding, which can also weld different materials such as copper and stainless steel. We also achieve good welding performance on various materials.
Weld cleaning before or after welding is a common application to improve weld performance and surface quality.
Gap cleaning widths can reach 80 mm, and weld cleaning widths can reach 10 mm.

Laser cleaning and rust removal technology has the advantages of high cleaning speed, good cleaning effect, no additional pollution, precise control, and no consumables.
Advantages of Portable Laser Welding Machines
1. It can be welded outdoors.
2. High welding speed, 2 to 10 times faster than traditional welding.
3. The weld is smooth and beautiful, with great depth and small taper. No sanding is required, saving time.
4. No deformation, no weld marks, and the workpiece is firmly welded.
5. Compared with contact welding, electrodeless laser welding reduces daily maintenance costs and greatly improves work efficiency.
6. Welding of thin stainless steel sheets, iron sheets, aluminum sheets, and other metal materials can perfectly replace traditional argon arc welding and electric welding.


Innovative BET 4-in-1 portable laser gun
Small size, easy to carry, suitable for daily work.
Handheld welding, flexible and convenient, with longer welding distance.
Adapt to different welding requirements, configure multiple safety alarms and status indicators, and respond immediately to abnormal situations.
Lamp body design and built-in protective cover.
When welding or laser cutting, more spatter is generated, especially when welding highly reflective materials such as aluminum alloys or carbon steel.
The inserted protective lenses can be easily replaced for routine operation and maintenance, maximizing the protection of the internal mirror against focusing, reflection, and collimation effects.
Switching from laser welding to laser cutting is as simple as replacing the welding nozzle with a cutting nozzle.
If you need to switch from laser welding/cutting to laser cleaning, you can simply replace the focusing lens insertion tool and cleaning nozzle for laser cleaning. Direct metal removal.
Cutting stainless steel is easy, you can cut straight or curved lines or any shape you want, and you can also cut steel with a thickness of 0 to 40 mm.
Laser welding nozzles include conventional welding nozzles and electric welding nozzles.
The advantage of the nozzles we use is a lower spray volume compared to conventional nozzles.
Depending on the material, there are brass and copper nozzles, with copper nozzles providing better heat dissipation than brass.
It also has the world's most reliable safety certification, including EU certification, among others.
It has a stable, high power of 3800 W and a welding speed of 40 m/min.
Welding of stainless steel, steel, aluminum alloys, etc.
Portable laser welding technology uses a laser beam as an energy source, which acts on the welding plate and creates a weld.
Not only does it solve the problems of traditional welding, but it also increases waterproofing when working underwater and on rainy days (completely avoiding the problem of being unable to work on rainy days, greatly improving work efficiency).

"I've been working in metal fabrication for over 12 years and have used all types of welding equipment—TIG, MIG, you name it. The BET 3800W laser welding gun genuinely impressed me. The build quality is excellent, and the operation is straightforward. Within minutes of unboxing, I was laying clean, precise welds on stainless steel.
What really sets this unit apart is the 4-in-1 functionality—cutting, cleaning, and welding in one compact machine. It significantly speeds up production in my workshop. If you're running a small manufacturing line or need reliable on-site welding, this is a solid investment. Highly recommended."

"I bought this laser welder mainly for maintaining heavy-duty tools and farming machinery. It works surprisingly well on thick steel parts and hard-to-reach areas. The 3800W output is no joke—it goes deep and saves me time. One star off only because I wish it came with more protective lens covers, but otherwise excellent machine."
