What are the advantages of laser welding machine over other welding machines?

Laser welding is one of the important aspects of the application of laser material processing technology. 1970s is mainly used for welding thin-walled materials and low-speed welding, the welding process is heat conduction type, that is, the laser radiation heats the surface of the workpiece, the surface heat

volume of the heat conduction through the heat diffusion to the interior, through the control of the width of the laser pulse, the energy, the peak power and the frequency of the repetition of such parameters as the melting of the workpiece, the formation of a specific molten pool. Due to its unique advantages, it has been successfully used in precision welding of micro and small

parts.

According to the control mode can be divided into: manual laser welding machine, automatic laser welding machine, galvanometer laser welding machine.

According to the laser can be divided: YAG laser welding machine, semiconductor laser welding machine, fiber laser welding machine.

Laser welding is a very high energy density laser beam irradiation to the two parts of the material, so that the local heat melting, and then cooled and solidified into one. Relative to the traditional welding process, laser welding has the following advantages:

1, no contact processing, no external force on the welded parts.

2, the laser energy is highly concentrated, the heat effect is small, thermal deformation is small.

3, can be welded high melting point, difficult to melt, difficult to weld the metal, such as titanium alloy, aluminum alloy. Can realize the welding between certain dissimilar materials.

4, the welding process has no pollution to the environment, in the air can be directly welded, the process is simple.

5, small weld joints, narrow weld seam, neat and beautiful, no need to deal with the post-weld or only a simple treatment process. Weld seam organization uniformity, less porosity, less defects, can reduce and optimize the parent material impurities, the mechanical strength of the weld seam is often higher than the mechanical strength of the parent material. Laser welding mechanical properties, corrosion resistance and electromagnetic properties are superior to conventional welding methods.

6, the laser can be accurately controlled, focused point of light is small, can be positioned with high accuracy, to achieve precision processing.

7, easy and computer numerical control system or robot, robot with the realization of automatic welding, improve production efficiency.

Laser welding has many advantages over ordinary traditional welding, first of all, its welding can be fully automated, as long as the host beforehand to enter the course of action can be, simple and practical.

Secondly, the laser welding spot is very small, with no welding place is the same color, which is more than ordinary welding is a black circle compared to the aesthetics is not comparable.

Another, he is a radiation-free welding machine without consumables, general welding, produced by the glare, toxic gases, etc. for the body has a great deal of harm, which for the operation of the welding workers is a great harm, while the laser welding is no odor, glare, etc..
