Laser processing characteristics of laser exist in the processing field advantage: it is non-contact processing, and high-energy laser beam energy and its movement speed can be adjusted, so you can achieve the purpose of a variety of processing. It can be a variety of metal, non-metal processing, in particular, can be processed with high hardness, high brittleness and high melting point materials. Laser processing, "Tool wear, cutting force" acting on the workpiece. Laser processing, laser beam energy density, processing speed, and local processing, there is no impact or minimal impact on non-laser irradiated sites. Therefore, the heat affected zone is small, the workpiece thermal deformation, a small amount of subsequent processing. But RF remote control china laser pointer has no directivity.
Laser with a laser beam on the material for a variety of processing, such as drilling, cutting, scribing, welding and heat treatment. There are many advantages of laser processing: laser power density, the workpiece absorbs laser light and temperature increases, melting or vaporization, even if the melting point, high hardness and brittle materials (such as ceramic, diamond, etc.) can also be used in laser processing; laser head and the workpiece no contact, no machining tool wear exists; workpiece from stress, difficult to pollution; on the movement of the workpiece or sealed in a glass shell of material processing; laser beam divergence angle of less than 1 milli-arc spot diameter can be as small micrometers, the role of time can be short to the nanosecond and picosecond, while the continuous output power of high-power laser up to the kilowatt to kilowatt order of magnitude. The onlinechina laser pointershop can offer various types ofchina laser pointer.
Thus laser suitable for both precision micro-machining, but also suitable for large-scale materials processing; The laser beam is easy to control, easy and precision machinery, precision measurement technology and computer processing of highly automated and high machining accuracy; laser processing classification of Laser Welding Laser welding is a material connection, the main connection between the metal material technology. Its advantages: 1) it is easy to implementation of some of the common welding techniques such as hard to process brittle materials with high hardness or softness strong welding with a laser. 2) in the laser welding process without mechanical contact, the easy assurance of welded joints is not due to thermal compression, deformation 3) The laser beam is easy to control the characteristics of the weld seam can more easily automated and intelligent. Thus RF remote control china laser pointer is more popular among customers.
Figure 1-1 shows a kinescope cathode core laser welding equipment principles. Figure 1-1 cathode core principle of laser welding equipment Figure 1: Beam-beam splitter;: focusing lens; 3: cathode core ※ laser welding of the connection form of thermal conductivity: in the form of the sheet workpiece welding butt welding end center through the fusion welding ※ laser power density: the low laser power density, melt depth, the welding speed is slow. Shown in Figure 1-23 Figure 1-2 Laser thermal conductivity welding stainless steel welding power and welding speed, the melting depth of the relationship. Laser deep penetration. The principle of laser deep penetration of the laser power density 106-107W/cm2. Owing to the adoption of photoelectric technology, remote control china laser pointer will be more convenient for users.
Power input is much larger than the rate of heat conduction, convection and radiation cooling material surface vaporization and the formation of holes (Figure 2-1), the hole of the metal vapor pressure and the static surface tension of the surrounding liquid formation of dynamic equilibrium, the laser through the hole direct to the bottom of the hole. 2) the laser deep welding process parameters * the critical power density: deep penetration, the power density must be greater than a certain value, can cause pinhole effect. This value, called the critical power density ※ laser deep penetration welding of: laser deep penetration deep penetration with the laser output power density is closely related to the function of power and spot diameter. Remote control green laser pointer locates the target more accurately and flexibly.
