Therefore, we must understand the various physical phenomena arising from the interaction between laser and metal as well as the relationship of these physical phenomena and laser parameters, and thus by controlling the laser parameters, the laser energy is mostly converted into the energy of the molten metal to reach welding purpose. Laser welding process parameters. Power density. The power density is one of the most critical parameters in the laser processing. Higher power density, in the microsecond time range, the surface can be heated to boiling point, resulting in a large number of vaporization. Therefore, high power density for the material removal of machining such as drilling, cutting, carving favorable. The two parties are discussing the result of manufacture supervision of     green laser pointer  .
Lower power density, the surface temperature reaches the boiling point to go through a few milliseconds, in front of the surface vaporization, the bottom of the melting point, easy to form the molten weld. Therefore, in the conduction laser welding, the power density in the range of 104 ~ 106W/CM2. 2, the laser pulse waveform. Laser pulse shape in laser welding is an important issue, especially for thin section welding is more important. When high-intensity laser beam shot to the surface, the metal surface will be 60 ~ 98% of the laser energy reflected is lost, and the reflectivity versus surface temperature. In a laser pulse period, the rate of change of the metal reflector. 3, the laser pulse width. The vice manager is in charge of management of    green laser pointer      workshop.
The pulse width is one of the important parameters of the pulsed laser welding, it is both different from the material removal and material melting parameters, the key parameters in determining the cost and volume of processing equipment. Defocus amount of welding quality. Laser welding usually requires a certain defocus, high power density of the laser focus at the spot center, easily evaporate into the hole. Leaving the laser focus plane, the power density distribution is relatively uniform. Defocused mode in two ways: positive and negative defocus defocus. Focal plane at the top of the of the workpiece being away from the focus, and vice versa for negative defocus. Geometrical optics theory, when the positive and negative to make a fuss about an equal corresponding power density is approximately the same plane, but actually the weld pool shape. The sales agreement of       usa green laser pointer      should be signed as soon as possible.
Negative defocus, the availability of greater penetration, which is related with the formation of the molten pool. The experiments show that the laser heating 50 ~ 200us material begins to melt, the formation of liquid metal and asked the sub-vaporization, the formation of city-pressure steam, and at very high speed jet, and a dazzling white. At the same time, high concentrations of vapor liquid metal movement to the pool edge, the formation of depression in the weld pool center. When negative defocus, the power density of material internal surface area is also high, easy to form a stronger melting, vaporization, so that the light pass deeper into the material. Therefore, in practical applications, when the requirements of the penetration depth larger negative defocus; welding thin material, it is appropriate defocus. Laser processing technology. The promotion of green laser pointer  will draw more attention of more customers.
Laser cutting laser cutting technology is widely used in the processing of metallic and nonmetallic materials, can significantly reduce processing time, reduce processing costs, and improve the quality of the workpiece. Modern laser have become a fantasy pursuit of cut iron drunk, "the sword". CO2 laser cutting machine company, for example, the composition of the entire system by the control system, motor system, optical system, cooling system, exhaust and blowing protection system using the most advanced CNC mode multi-axis laser from speed impact energy cut, while supporting the DXP, PLT, the CNC, and other graphics formats, and to strengthen the interface drawing processing capabilities; superior performance imported servo motor and transmission-oriented structure to achieve good movement precision at high speed. Laser cutting is laser focused energy to achieve high power density. The marketing channel of green laser pointer of the agent is multiple.
