Introduction of Handheld Laser Welding Machine

Handheld laser welding machine is a portable laser welding equipment, mainly used for high precision laser welding of metal materials. The following are the basic principles and features of the handheld laser welder:


Basic principle:

Handheld laser welding machine produces a high energy laser beam through the laser, which generates a strong thermal influence in the welding area, instantly heating and melting the workpiece locally, forming a certain molten pool. Through the surface tension and surface tension of the welding material, the molten pool is wetted, diffused, and grain growth under the action of the light spot, and finally the welding of the metal material is realized.

Product features:

High precision: Handheld laser welding machine can realize tiny weld width and high precision welding, which is suitable for fine processing of precision parts.

Fast welding: laser welding is fast and the melting depth is shallow, which can complete the welding task in a shorter time.

Low heat impact: The laser welding process has a small heat-affected area and less impact on the material around the workpiece, which reduces the risk of distortion and thermal cracking.

Non-contact welding: Laser welding is a non-contact process that requires no contact with the workpiece, which reduces workpiece surface damage and contamination.

Flexible: The handheld design allows for more flexible operation and is suitable for welding workpieces of all shapes and sizes.

Easy to operate: Handheld laser welders usually have a simple operator interface and control system, which is easy to operate and control.

Factors Affecting Laser Welding Thickness

There are many factors that affect the thickness of laser welding, mainly including the following aspects:


1. Laser power:

- Laser power is one of the important factors affecting the thickness of welding. Higher power lasers can provide more energy, allowing the laser to better penetrate the surface of the material and achieve deep welding.

- High-power lasers can transfer more heat to the welding area in a shorter time, thereby achieving a deeper molten pool and ultimately affecting the welding thickness.


2. Beam quality:

- Beam quality refers to the focusing degree and focusing ability of the laser beam, which is an important indicator for measuring the quality of the laser beam.

- High-quality beams can focus better and increase the energy density of the focus, thereby achieving deeper welding. Low-quality beams may cause energy dispersion and affect the welding quality.


3. Beam focus position:

- The beam focus position is closely related to the welding depth. The appropriate focus position can effectively focus the laser energy in the welding area to achieve the ideal welding depth.

- If the focus position is too high or too low, it may cause insufficient or too deep welding depth, affecting the welding effect.


4. Scanning speed:

- Scanning speed refers to the speed at which the laser beam moves on the surface of the workpiece. Higher scanning speed can reduce welding time, but it will affect welding depth.

- Appropriate scanning speed can ensure that the laser stays in the welding area for a sufficient time, so that the material is fully melted and a good weld is formed.


5. Laser beam diameter:

- Laser beam diameter will also affect welding thickness. Generally speaking, a smaller laser beam diameter can increase the focus energy density and achieve deeper welding.

- However, it should be noted that too small laser beam diameter may cause the welding speed to be too slow, affecting production efficiency. Therefore, it is necessary to make a reasonable choice in practical applications.


In summary, factors such as laser power, beam quality, beam focus position, scanning speed and laser beam diameter will affect welding thickness. It is necessary to comprehensively consider and adjust the corresponding parameters in practical applications to achieve the desired welding effect.

Laser Welding Thickness Material Considerations

In the laser welding process, the choice of material is one of the important considerations that affect the weld thickness. The following are some factors involved in material selection that help determine the maximum weld thickness of laser welding:


1. Thermal conductivity:

The thermal conductivity of a material refers to its ability to conduct heat. High thermal conductivity will cause the weld to have a higher heat dissipation and thermal conductivity effect, making it difficult for the weld area to reach a sufficient melting temperature.

For materials with high thermal conductivity, higher laser power is usually required to achieve sufficient welding depth, or it is necessary to increase the welding speed to improve welding efficiency.


2. Absorption coefficient:

The absorption coefficient of the material to the laser affects the conversion efficiency of the laser energy. A lower absorption coefficient may make it difficult to effectively absorb and convert the laser energy into heat, thereby affecting the welding depth.

For materials with lower absorption coefficients, higher laser power or longer welding time may be required to achieve the desired welding effect.


3. Melting point:

The melting point of the material also has an important influence on laser welding. A higher melting point requires a higher laser power to melt the material, which affects the welding depth.

At the same time, for materials with different melting points, parameters such as laser power and welding speed need to be adjusted to achieve the appropriate welding depth.


4. Penetration:

The penetration of the material determines the formation of the molten pool and the degree of melting during welding. Generally, better penetration can help achieve deeper welding.

Some materials have good penetration and can achieve deep welding, while for materials with poor penetration, it is necessary to pay attention to adjusting the welding parameters to improve the welding quality.


5. Focus position:

The appropriate focus position is the key to achieving deep welding. Focus that is too deep or too shallow will affect the welding quality and depth. The correct focus position can effectively focus the laser energy in the welding area to achieve the ideal welding effect.

For different materials, it may be necessary to adjust the focus position to find the most suitable focus position.


When selecting welding materials and determining laser welding process parameters, these factors need to be considered and appropriate adjustments should be made to ensure welding quality and efficiency.


Maximum Thickness of Laser Welding Machine with Different Power

The power of the laser welding machine is one of the important parameters that affect its welding thickness. Generally speaking, the higher the power of the laser welding machine, the greater the welding thickness. The following is a reference for welding thickness at different laser powers:
