Realize welding at any angle. In addition, he can also complete the cutting, welding and cutting can be switched freely, just change the welding copper nozzle to the cutting copper nozzle, which is very convenient.
Good welding effect
Hand-held laser welding is thermal fusion welding. Compared with traditional welding, laser welding has a higher energy density and can achieve better welding results. The welding area has little thermal influence, is not easy to deform, blacken, and has traces on the back , the welding depth is large, the melting is sufficient, firm and reliable, and the weld strength reaches or even exceeds the base metal itself, which cannot be guaranteed by ordinary welding machines.
Weld seams do not need to be polished
After traditional welding, the welded joints need to be polished to ensure smoothness and not roughness. The handheld laser welding just reflects more advantages in the processing effect: continuous welding, smooth and no fish scales, beautiful and no scars, less follow-up grinding process.
Welding without consumables
In most people’s minds, the welding operation is “goggles in the left hand and welding wire in the right hand”. However, with the hand-held laser welding machine, welding can be easily completed, which reduces the cost of materials for production and processing.
With multiple safety alarms
The touch switch is only effective when the welding tip touches metal, and the light will be automatically locked after removing the workpiece, and the touch switch has a body temperature sensor. High safety, ensuring the safety of the operator during work.
Labor cost saving
Compared with arc welding, the processing cost can be reduced by about 30%. The operation is easy to learn and quick to use, and the technical threshold for operators is not high. Ordinary workers can go to work after a short training, and can easily achieve high-quality welding results.
Handheld Fiber Laser Welding Machine Operating Modes
1.Working principle: Laser welding is non-contact welding. No pressure is required during the operation. The laser beam of high energy intensity is directly irradiated on the surface of the material. Through the interaction of the laser and the material, the inside of the material is melted, and then the crystal is cooled to form a weld seam.
2.Operation mode: Hand welding, easy to operate.
3.Use characteristics: According to the different ways of use, laser welding machines are divided into handheld laser welding machines and desktop laser welding machines. Compared with the desktop laser welding machine, the handheld fibre laser welding machine is mainly for laser welding of long-distance and large workpieces. Welding on thin stainless steel plate, iron plate, galvanized plate and other metal materials can perfectly replace the traditional argon arc welding, electric welding and other processes.
Types of Handheld Fiber Laser Welding Machine
Continuous wave fiber laser welding machine
A continuous wave fiber laser welding machine delivers a continuous outburst of energy for welding.
This type of machine has an upslope when it starts; it continuously sends laser power, and a downslope when turned off. It works non-stop and is suitable for high-volume production. This type of welding is suitable for heavy projects where deep penetration is required. It is also ideal for crack-sensitive materials like stainless steel.
Pulsed fiber laser welding machine
The pulse fiber laser welding machine works at small pulses instead of emitting continuous beams. A pulse laser welder can produce more energy than its average power. It is suitable for spot welding where high power is required.
The welding machine runs for a smaller period, so it is suitable for heat-sensitive or very thin materials. It also works well on reflective material, as a power spike lasts a fraction of the pulse time.
Applicable Materials of Handheld Fiber Laser Welding Machine
Stainless steel
It can work on any grade of stainless steel and may be useful in welding stainless steel utensils, furniture, or decoration pieces. Due to the narrow beam, the heat-affected zone is small, which means no defects in the surrounding material. You can weld thin plates as well.
Carbon steel and alloy steel
Laser welding machines can handle carbon steel well. A fiber laser welding machine with equal precision can work well on carbon or alloy steel. The increased carbon content can risk pores or welding cracks, but the fiber laser welding machine’s focused high-power beam eliminates and avoids cracks.
Silicon steel
Silicon steel is a common material for making electric equipment and has magnetic properties. It is difficult to weld with ordinary methods due to the risk of cracking due to high silicon content. A handheld fiber laser welding machine can offer effective welding with no distortion.
Spring steel
Spring steel is used in making springs for different industries. It is high-carbon steel that is challenging to weld. It is also easy to deform or get cracks. It is also a thin material. A narrow laser beam gives precise control over the welding process and can give reliable weld quality.
Galvanized sheet
Galvanized steel has a layer of zinc to protect it from corrosion. However, a handheld laser welding machine can give desired results.
Aluminum and alloys
Aluminum and its alloys are used in many industries. They have high thermal conductivity and low melting points. It is a highly reflective material and can be challenging to weld. The highly focused laser beam ensures precise and effective welding of aluminum and its alloys.

Components of Handheld Fiber Laser Welding Machine
Fiber laser source
The fiber laser source is part of fiber laser delivery from where laser power is produced. It comprises laser diodes, fiber optic cable, and a laser resonator.
Welding head
It’s the part from where a laser beam is generated. It focuses the beam on workpieces. The welding head generally has lenses and a control system to adjust the laser beam frequency, power, and shape.
Power supply
A power supply component provides the electric power for the laser source and other components.
Control system
A control system consists of key parameters that should be adjusted before the welding machine starts. They can be the laser beam’s power, shape, and speed.
Cooling system
A cooling system dissipates the heat and cools down the machine and workpiece. The cooling system keeps the temperature of the machine in control as well. The device can use a water or air cooling system.
Handheld device
A handheld device is part of the machine that the welder holds in hand and directs the laser beam on the workpiece. It has a trigger or button that the welder can press to activate the laser beam and start the welding process.
How Does a Handheld Fiber Laser Welding Machine Work
A handheld welding machine works with a fiber laser system. The first process is to generate the laser power. A fiber laser source comprises a laser diode, fiber optical cables, and optical resonators. The laser source produces light that runs through fiber optic cables and passes through lenses or mirrors. The light is reflected back and forth until amplified as required for the job.
The laser beam is focused on the workpiece through a laser head. The welding head usually has a lens control to adjust the size and power of the laser beam. Once the beam touches the exact spot, it melts the material and joins the two parts together.
The molten matter solidifies and forms the weld. Some handheld welding machines have a cooling system to dissipate the heat and prevent overheating.
Factors to Consider When Choosing a Handheld Fiber Laser Welding Machine Welder
Power output
Power output determines the capacity of your machine. A higher-power machine can work on thick and tough metals. But for jewelry making and welding delicate parts, you may not need a higher power. So select the power output depending on your welding needs.
Welding speed
Laser welding machines work much faster than traditional argon arc welding, TIG welding, or MIG welding techniques. However, make sure you check the welding speed to suit your production needs.
Spot size
It is the maximum size of the laser beam that a machine can generate. The spot size is important to understand the heat the laser machine produces and how deep it can penetrate into the material. It can also be helpful to check before selecting the machine, as selecting too narrow a spot size for larger parts may take a long time to weld.
Laser beam quality
Beam quality refers to the shape and distribution of the laser beam. A good quality beam will give a smooth weld without any distortion. Ask your suppliers for the laser machine specifications to check the parameters.
Cooling system
A cooling system of a laser welding machine is essential to check. It dissipates the heat that prevents the material from overheating. It is also essential for the protection of the laser machine itself. Two types of cooling systems can be used in laser welding machines, which are water cooling systems and air cooling systems.
Ergonomics and usability
The size of the handheld laser welding machine should also be considered. When you are buying a handheld device, it’s ergonomic. Size and portability are important, so check the technical specs and see if they suit your needs.
Cost
The last and most important is cost. The cost of a handheld laser welding machine depends on the power and other features. Select one that suits your needs while staying within the budget.
