What parameters should I check before using?
All usage parameter settings are clearly stated in your owner's manual. Therefore, we will only describe a few commonly used parameters.
Adjust power
Careful consideration should be taken when deciding the welding power that is necessary for a job. If too much power is used, then additional energy will be consumed and resources might go to waste.
Before getting started, it's important to consult the welding parameter table in order to select the suitable welding power.
Beam diameter
For optimal performance, we recommend selecting a laser beam with a diameter between 0.2 and 2mm.
Pulse frequency
At excessive frequencies, more energy is utilized on the metal which can lead to inefficient welding.
Pulse waveform
It's vital to use the appropriate waveform for each metallic material; failing to do so may result in energy loss and poor welding results. It's important to select the correct waveform in order to optimize welds.
Fiber laser welding machine working principle
The main principle of the fiber laser welding machine is to emit a high-energy, high-density laser beam through an optical fiber to melt and vaporize the metal at the weld to form a molten pool.
The key advantage of using a fiber laser welding machine is the deep penetration of the laser beam. This allows for very strong welds, even on thicker materials.
Fiber laser welding machines can be used for many different applications, including welding two pieces of metal together, repairing metal parts, and even cutting metal. This makes it a versatile tool for many different industries.
Classification of handheld laser welding machines
Handheld laser welding machines can be classified according to their laser heads and lasers
Classification by Laser
Handheld laser welding machines can be categorized by the type of laser they use.
There are three main types of lasers used in welding applications:
Fiber Lasers: Fiber lasers are the most common type of laser used in welding applications, including handheld welding machines. These lasers use fiber optic cables to deliver the laser beam to the welding point, which makes them very flexible and easy to use. Fiber lasers are also very efficient and can produce high-quality welds on a variety of materials.
CO2 lasers: CO2 lasers use a mixture of carbon dioxide, nitrogen, and helium to produce a high-energy laser beam. These lasers are commonly used in industrial welding applications, but are less commonly used in handheld welding machines due to their large size and weight.
Nd: YAG Laser: Nd: YAG (Neodymium-Doped Yttrium Aluminum Garnet) lasers use crystals to generate a high-energy laser beam. These lasers are highly precise and can produce high-quality welds on a variety of materials, but they have seen less use in handheld welding machines due to high cost and complex design.
Classification by laser source
Handheld laser welding machines can also be classified by the type of laser source they use.
There are two main types of laser sources used in welding applications:
Solid-state lasers: Solid-state lasers use a solid material, such as a crystal, as the lasing medium. They are commonly used in welding applications due to their high power output and excellent beam quality. Solid-state lasers are also very efficient and can produce high-quality welds on a wide variety of materials.
Gas Lasers: Gas lasers use a gas, such as carbon dioxide or helium-neon, as the lasing medium. They are less commonly used in welding applications than solid-state lasers. However, they are still used in some applications, especially in medicine and science.
Solid state lasers are the most commonly used type of laser source in handheld laser welding machines because of their high power output and excellent beam quality.
Solid state lasers can be further divided into different types such as fiber lasers, disk lasers and diode pumped lasers.
The choice of laser source depends on the specific welding application, the materials being welded, and the desired power output and beam quality.

Factors affecting the quality of laser welding
The quality of laser welding is affected by a number of factors, including the type of laser used, the type of material being welded, the thickness of the material, the focus of the laser, the speed of the laser, and the power of the laser.
In order to produce high-quality laser welds, it is important to understand how these factors influence the welding process.
Different types of lasers can be used for laser welding, but CO2 lasers are the most common. CO2 lasers emit a beam of infrared light that is absorbed by the material being welded, causing it to heat up and melt.
The focus of the laser is important in determining the width of the weld bead. A higher focus will result in a narrower bead, while a lower focus will result in a wider bead.
The speed of the laser is also acritical factor in laser applications. The faster the laser, the shorter the pulse duration and the more precise the result. For instance, in laser welding, a faster laser can make a more precise weld with less heat deformation.
In laser cutting, a faster laser can cut through thicker materials with the same level of accuracy. The speed of the laser is dependent on factors such as the power of the laser, the characteristics of the material being processed, and the motion control system.
