Heat transfer welding laser beam power density is less than 10 W / cm, the laser metal surface heated to the melting point and boiling point, welding, metal surface will absorb the laser energy into heat energy, so that the metal surface temperature l high melting, heat transfer by thermal conduction to the metal interior, so that the melted zone gradually expanded and solidified to form the solder joints or welds, the penetration depth contour approximately hemispherical. The welding mechanism called the heat transfer welding, which is similar to the TIG arc welding process, as shown in Figure 1 (a). The main features of the heat transfer welding is the power density of the laser spot, much of the light metal surface reflection, light absorption is low, weld penetration depth. cheap Laser Pointers can be used in many locations by the customer.
Slow welding speed is mainly used for thin (thickness <1 mm), small parts of the welding process 527 Harbin Institute of Technology 2, deep penetration when the power density on the laser spot is large enough (≥ 106W/cm2), the metal in the laser irradiation is rapidly heated, the surface temperature within a very short time (10 to 10 s) rise to the boiling point, the metal melting and gasification. Gasification when the metal, the resulting metal vapor to leave the bath to a certain speed, the escape of the metal vapor to produce an additional pressure on the molten liquid metal (for example, aluminum, p ≈ 11MPa; for steel, p ≈ 5MPa) bath metal surface down to depression, the laser spot to produce a small pit [Figure 1 (b)]. The long life time of green laser 5mw is another concern for the customer.
Pits to further deepen the liquid metal when the metal vapor beam in the holes at the bottom of to continue heating the gasification on the one hand the oppression Bottom, on the other hand, steam flying out to the pit outside the molten metal is pressed against bath four weeks. This process continues, will form an elongated holes in the liquid metal. When the beam energy produced by metal vapor recoil pressure of the liquid metal surface tension and gravity balance, the holes are no longer continue to deepen, the formation of a stable depth of hole and welding, so called laser deep penetration [Figure 1 (b)]. If the laser power is large enough and the material is relatively thin, laser welding of the hole throughout the plate thickness and can receive the back part of the laser. The sampling inspection will be performed for green laser 5mw.
This welding method can also be called to effect welding of sheet metal laser holes. From the mechanism point of view, there are holes in the premise of the effect of welding of deep penetration and holes are welding process, the difference was not essentially different. The conditions of energy balance and the balance of material flows can be generated when the holes are stable phenomenon. As long as the beam is sufficiently high power density, small holes can always be formed. The holes are filled with weld metal under continuous irradiation of the laser beam generated by the metal vapor and plasma (Figure 2). This has a certain pressure of the plasma to the workpiece surface space eruption, the formation of a range of plasma cloud above the hole. The inspection of green laser 5mw should be implemented step by step.
Holes around the bath surrounded the outside of the molten metal is not molten metal and part of the solidification of metal, gravity and surface tension of the molten metal to make holes to bridge the trend, the continuous generation of metal vapor is trying to maintain a small hole exist. Beam incident substance continuous escape hole with the movement of the beam, the holes with the beam movement, but its shape and size is stable. -8-6 As a heat source with a laser beam welding method. Welding, laser beam of the laser emission, high power density (108 to 1012 watts / cm 2) poly shrunk a focused laser beam to bombard the surface, resulting in heat, melt the workpiece (see Figure laser welding schematic). Correspondingly, the necessary actions and measurements of green laser 5mw should be taken.

Harbin Institute of Technology laser beam is coherent light beam with a single frequency, the launch does not produce divergent available lens polycondensation the focus of a certain size (0.076 to 0.8 mm in diameter). Small focus of the laser beam can be used for welding, cutting and punching; major focus of the laser beam can be used for surface heat treatment. The laser beam can be used to mirror any changes of direction, thus welding the parts of the general welding methods can not be close to the workpiece. Such as the use of fiber optics to guide the laser beam, the better to increase the flexibility of the welding. Laser sub-solid lasers and gas lasers. The solid-state laser materials used for the ruby, neodymium glass, etc.. Solid-state laser output energy is small, about 1 to 50 joules, pulse laser. It means that 5mw green laser can be used by the stargazer.
Heating pulse duration is very short (less than 10 milliseconds), thus solder joints can be as small as tens to hundreds of microns, and high precision welding, suitable for the welding of the metal foil of less than 0.5 mm thickness, continuous welding or 0.6 mm diameter wire butt welding, solid state lasers are widely used in the welding of miniature, precision, densely arranged on the heat-sensitive electronic components and equipment parts. Gas lasers used in materials for carbon dioxide or argon plasma gas, power (15 to 25,000 watts), to produce a continuous laser, continuous welding, welding of 0.12 to 12 mm thick low-alloy steel, stainless steel, nickel, titanium, aluminum and other metals and their alloys. Low-power CO2 laser welding also non-metallic materials such as quartz, ceramics, glass and plastic. It is about the color of the laser beam light emitted by 5mw green laser.
Laser welding of high quality, sometimes more than the electron beam welding and quality. Laser welder, especially high-power laser welding machine, high cost, and efficiency is very low, usually only 5 to 10%, the best 20%, penetrating power not as the electron beam. With a laser beam in the air or protective gas welding and convenient than the electron beam welding. The main features of laser welding compared with other conventional welding techniques, laser welding of the main advantages are: speed, depth, small deformation. Room temperature or under special conditions, welding, welding equipment device is simple. For example, the laser through the electromagnetic field, the beam will not be offset; laser welding can vacuum, air and a gas environment, and through the glass or transparent material on the beam welding. The laser beam light of cheap Laser Pointers can be seen very clearly.
Welding of refractory materials such as titanium, quartz, and welding the opposite sex material to good effect. Laser focus, high power density welding of high-power devices, the aspect ratios up to 5:1 up to 10:1. Can be micro-welding. Available by focusing a small laser beam spot, and can precise positioning can be applied to the automated production of large quantities of micro, small parts welding. Welding can be difficult to close the site, the implementation of long-distance non-contact welding, and has great flexibility. In recent years, the YAG laser processing technology used in fiber optic transmission technology, access to a wider range of promotion and application of laser welding technology. The laser range of this kind of 5mw green laser can meet the special requirement.
The laser beam is easy to realize the beam splitter according to time and space, at the same time processing of multi-beam and multi-bit processing, provided the conditions for more precise welding. Laser welding, however, there are some limitations: the requirements of the weldment assembly of high precision, and the requirements of the position of the beam on the workpiece can not have a significant offset. This is because the laser focus spot-foot rain-inch weld narrow, the filler metal materials. If the workpiece assembly precision beam positioning accuracy is below standard, it is likely to cause welding defects. Lasers and their associated systems, high cost, one-time investment. Laser welding heat conduction. Laser welding is a high-intensity laser beam radiation to the metal surface through the interaction of laser and metal, the metal melt formed welding. 5mw green laser used for the star gazing can be the green laser pointer.

The experimental setup is shown below. Pumping light converged after collimation focusing system into a diameter of 400um focused spot is injected into the work material internal radius of curvature of the output mirror M1 is 50 mm, concave-plated 946 nm high reflector (HR) film, 473 nm (AR anti- ) color film, the first two sub-arm all-trans mirror M2 radius of curvature of 200 mm, concave-plated 946 / 473nm the HR membrane. 1, arm length of 72 mm 2, arm length is 29 mm. Experiments in the gain medium Nd: YAG crystal (Φ4mm x 3mm) the left plated the 808 nmAR/946 nm, the HR membrane as an end mirror, plated 946 nm, the other end of the AR film. Multiplier device is Class I critical phase-matched LBO crystal (3 mm x 3 mm x 9 mm). And then the laser technology of cheap Laser Pointers becomes the key point.
Both ends of the surface are coated AR-color film, placed in the first two sub-arm beam waist at 946 nm / 473 nm. Further increase the cooling, the system may have a greater power output. The laser classification, there are two ways to classify the laser. A state of matter, surface active medium. This can be divided into a gas, liquid, solid, and semiconductor lasers. Various types of lasers have their own characteristics. Gas laser monochrome, such as helium - neon laser monochrome than ordinary light, 100 million times high, and gas lasers, a wide variety of work material, and therefore can produce many different frequency laser. However, due to low gas density, the laser output power corresponding smaller. The financing plan preparation of laser light show equipment needs to be finished timely.
Solid-state lasers is the opposite, high energy, high output power, but work fewer material types, and the monochrome poor; the biggest characteristic of the liquid laser is the laser wavelength can be within a certain range of continuous transformation. Of this laser is particularly suitable for the laser wavelength with the stringent requirements of occasions; semiconductor laser is characterized by small size, light weight, simple structure, but the output power is small, poor monochromaticity. Another classification is the classification of the particle structure of the active medium can be divided into atoms, ions, molecules and free electron laser. Helium - neon laser to produce laser emission by neon atoms, the ruby laser to produce the laser is fired by the chromium ions.  laser light show equipment can emit the very special red laser beam.
In addition to carbon dioxide molecular laser, its frequency can be continuously changed. And can cover a very wide frequency range. A variety of laser active medium, a different approach. In general can be divided into three methods: the use of high-intensity light, with power to the electronic and less with the third method - nuclear radiation. Lasers used in optical fiber communication optical fiber communication, the light source used in three types: semiconductor lasers, semiconductor light-emitting diodes and semiconductor lasers. In the actual optical fiber communication systems, usually use the first two. Instead of semiconductor lasers, gas lasers, solid-state lasers, although they are first made coherent light source. This kind of laser light show equipment can emit the red laser beam light.
However, due to its size is too big, not suitable for small size fiber used in conjunction with, only for some special places. The semiconductor laser semiconductor laser is a laser diode, denoted by the LD. It was invented in 1960 by the former Soviet Union scientists H.Γ. Basov. The structure of the semiconductor laser is usually from the P layer, N and the formation of double-heterostructure active layers. The light-emitting semiconductor laser is the principle of the use of light by stimulated emission of radiation. In the distribution of inversion electrons in the external incident photon excitation, synchronized emission of photons by stimulated emission of photons and the incident photon is not only the wavelength and phase, the same direction. Strong emission, so that by the weak incident incentive to play the role of optical amplification. So that the customer or others can see the red laser beam light of laser light show equipment very clearly.

In China, the 2008 small and medium-power laser cutting equipment market size of about 402 million yuan, with the rest of the world in 2009 by the international financial crisis, China's small and medium-sized power cutting machine market growth is slowing down. Expected in the next two years under the impetus of industrial upgrading and technological transformation of China's manufacturing industry, small and medium-power laser cutting equipment market will quickly enhance and maintain high growth. The type of laser. Laser (a laser) means light amplification by stimulated emission, is a high quality light source. Laser (LASER) is a light source of the actual invention of the 1960s. LASER is the acronym for the English "stimulated emission optical amplification". It is during the working of laser lights for sale.
Laser there are many kinds of size as large as several football fields, as small as a rice or salt. Gas lasers, helium - neon lasers and argon lasers; solid-state lasers have a ruby laser; semiconductor lasers with laser diodes, like the CD player, DVD player and CD-ROM. Each laser has its own unique laser method. The laser has many features: First, the laser is monochromatic, or single frequency. Some lasers can produce different frequencies of laser, but these lasers are isolated from each other, and separate use. Second, the laser is coherent light. The coherent light is characterized by its light waves are in sync, the entire beam is like a "wave train". Therefore, the customer can buy cheap Laser Pointers of the best quality and performance.
Again, the laser is highly concentrated, that it would go a long distance will be dispersed or convergence. Laser classification is to see from what angle, red laser, blue laser, green laser based on frequency of distinction from the principle of the He - Ne laser, CO2 laser, diode laser, excimer laser, dye laser, argon ion laser, nitrogen laser, YAG laser, and so there are many. points from the continuity of a continuous laser and pulsed laser, pulsed laser microsecond (10e-6 seconds), there are ns (10e-9 seconds), skin seconds (10e-12 seconds), and femtosecond (10e-15 seconds) laser. In addition, generally based on the intensity of the laser will be divided into one, two .... and so on. It is to digest and absorb the imported technology of laser lights for sale.

However, because the machine is relatively TIG flexibility, some large-scale mold is not suitable for laser welding, laser used in the repair of large mold parts and some mobile phones, plastic molds and similar to its size and precision mold. Often a small corner defect to be scrapped before the laser repair after normal use, and a few solder joints concerned to restore the loss of tens of thousands or even hundreds of thousands of It also determines the mold repair industry, low-input high-return characteristics. Mold welding program-making process learned that mold welding industry prospects through market research, we have proposed the manufacture of mold welder program, the basic idea is modified on the basis of the origin welder. Several of which focus in part. Normally, three to five pieces of presenter laser pointer should be inspected at the same time.
To be able to adapt to the welding of high strength, high hardness materials, to a substantial increase of laser energy; to increase in order to ensure continuity and uniformity of the solder joint due to some larger molds, laser cavity made of the cantilever; two-dimensional table, place the mold instead of the previous spot welder, basic hand positioning, laser welding, classification and principle based on the mode of action of laser on the workpiece or the laser beam output to the different ways can the laser welding pulsed laser welding and continuous laser welding, the former forming a circular solder joints, which form a continuous weld pulse welding energy input to the workpiece is intermittent pulse. The extensive use of pulsed lasers in pulsed laser welding is a YAG laser. The log of Laser Pointers has contained a lot of information.
The repetition rate of YAG laser used is wide. Can also be continuous output YAG lasers and CO2 lasers through the gate to open or close above the laser light to be used for pulse welding. According to laser welding, the weld formation characteristics can be laser welded into the heat conduction welding and deep penetration (holes laser welding). Depth is limited to mold welding is thermal conduction welding in the pulsed laser welding, the principle is when the laser power density of 10 W/cm2, the laser will be elevated metal surface temperature of the melt, from the micro, laser inhalation of metallic materials under the surface of 10-5cm. Photon energy absorbed by the conduction electrons, the electrons in the energy passed to the lattice within 10-11 ~ 10-10S. And normally the real power of presenter laser pointer will be a little bit lower than the nominal power.
That the electronic temperature is equal, in order to establish the concept of the metal surface temperature T after time greater than 10-9S. Laser heating of metal can be seen as a surface heat source in the surface layer of light energy into heat, to the spread of metal depths follow the general heat conduction law, and then through the thermal conduction the internal heat transfer to the metal, the molten region expand gradually solidified after the formation of solder joints, the penetration depth contour approximately hemispherical, which is characterized by the use of the laser spot power density, a large part of the light reflected by the metal surface, the light absorption rate lower melting pool to form a long time. and the melt depth, used for the welding of small parts. For the laser torch, different kinds of presenter laser pointer will own different level of the highest power.
When the energy of the laser irradiation to the surface, some energy is reflected, part of the energy is absorbed, the transparent material on the part of the energy transmission. Transmission rate is zero for the metallic materials, plus the total energy of irradiation 1 unchanged, so if the increase in the reflectivity of the material will reduce the absorption rate, and vice versa was established. Laser marking or welded samples, we often encounter the Au, Cu, or brightness high stainless steel and other materials, such materials is their own reflection is higher than other materials or surface roughness is very small resulting in high reflectivity. The high reflectivity determines the relatively low absorption rate, so often we increase the laser energy to achieve the required effect. It is done by the specific personnel who specialize in the test and commission of the power of presenter laser pointer.

The application of laser technology in industry. Due to the adaptability, good processing quality, high precision, high efficiency, effective, multi-processing methods, pollution and other advantages of laser technology is widely used in industrial fields. Laser Rapid Prototyping: The materials used in laser manufacturing model is a liquid photosensitive resin in the absorption of ultraviolet laser energy after coagulation, changes into a solid material. To create a model compiled program input to the computer. Laser beam to the laser output optical system controlled by computer, scan it on the model material characterization, wherever he went in the laser beam, the original is the solidification of the liquid. Laser beam in the computer's command to make an End scan depicts. Here will introduce the pulse function application of wireless presenter laser pointer.
Will photosensitive polymer material layer by layer solidification, the accumulation of accurate sample, creating the model. Therefore, the manufacturing model in this way, fast, and sophisticated model made out of. The technology has been widely used in aerospace, electronics, automotive and other industrial fields. Laser cutting: laser cutting technology is widely used in the processing of metallic and nonmetallic materials, can significantly reduce processing time and reduce processing costs, improve the quality of the workpiece. Pulsed laser for metal materials, continuous laser for non-metallic materials, which is an important application field of laser cutting technology. Laser application in the industrial field limitations and shortcomings, such as using a laser to cut the food and plywood are not successful, the food is cut at the same time burning. It is for the improvement and enhancement of wireless presenter laser pointer.
Cutting plywood in the economy is still far from substandard operator. Laser welding: laser beam in the material, it will be heated to melting, so that the components are joined together with docking, that is welded. Laser welding than the smaller power of the laser beam cutting metal, the material to melt without it gasification become a continuous solid structure after cooling. The laser welding technology has dissolved pool purification effect, would be pure weld metal, apply to the similarities and differences between the metal material welding. Due to the high laser energy density, melting point, high reflectivity, high thermal conductivity and physical properties vary a great deal of metal welding is particularly beneficial. Using laser welding does not require any solder, so to exclude the possible contamination of welded components. It is for the development of Laser Pointers in the recent domestic market and oversea market.
Secondly, the laser beam can be optical systems together into very thin diameter of the beam, in other words, the laser can be made very fine torch, doing precision welding work; laser welding and components not in direct contact, that is, non-contact welding, fragile and thus material does not matter, you can also away from our side components for welding, can also be placed in the vacuum chamber components welded together. Laser welding of these characteristics, so it is particularly popular in the microelectronics industry. Laser engraving: engraving, laser graver than ordinary chisel is more convenient and rapid. Ordinary chisel in hard materials, such as granite, steel plate for engraving on, or in soft materials. If the customer presses the button of wireless presenter laser pointer.
Such as leather for carving, it is more difficult, engraved with a pattern takes a long time. If the use of laser engraving is different, because it is the use of high energy density laser local irradiation of the workpiece, so that the surface material gasification or color change of the chemical reaction occurs, thus leaving a permanent mark an engraving method. It does not have contact with materials, materials, hard or soft, does not hinder the speed of engraving. Laser engraving technology is one of the largest areas of application of laser processing. Regardless of the speed of a hard material, or carved in the soft materials, depicts this chisel for carving. If compatible with the computer to control the laser beam moves, the carving can also be automated. The small and short characteristic of wireless presenter laser pointer makes the customer carry the laser pointer around much more easily and conveniently.
