When the absolute value of the small defocus amount, the laser spot diameter and laser power density, faster expansion of solder bath, but the small diameter of the initial key-hole; the opposite case, the larger defocus amount, the initial the diameter of the Keyhole, but the molten pool expansion slows down, the solder joint size is not necessarily great. A certain laser power and welding speed, only the focus is within the best position to get maximum penetration and good weld shape. The impact of deep welding process parameters and the effect of heat conduction welding and deep penetration welding quality difference between the heat conduction welding and deep penetration the most basic difference is that the former pool surface and remain closed, while the latter bath is a laser beam to penetrate into holes. There are some specific and professional requirements towards green laser pointer .
Welding thermal conductivity of the system disturbance smaller, because the radiation of the laser beam does not penetrate the welded materials, so in the conduction welding process to weld difficult to be gas-invasive; deep penetration, the continuous closure of holes can lead to holes . The influence of the plasma in deep penetration welding process, high power density laser beam to the workpiece surface, the material is quickly melting evaporation, the formation of steam clouds above the workpiece. In the process of leaving the surface of the workpiece at high speed steam clouds located in the incident beam path by heating, under certain conditions will be quickly ionized plasma is produced. Plasma on the laser absorption, refraction and scattering. green laser pointer used for the star gazing can be the green laser pointer.
Therefore, in general the top of the molten pool of plasma weaken the laser energy to reach the workpiece. And influence the beam focusing effect on the welding. Usually a secondary side of the inflatable to get rid of or weaken the plasma. Used as an auxiliary gas such as Ar, He, N2 and CO2. Different auxiliary gas to suppress the ionization potential of the plasma effect of the gas, thermal conductivity and dissociation energy and so on. When the auxiliary gas flow rate less than the critical flow, the gas ionization potential to play a leading role. The highest ionization potentials of these four gases He, the corresponding order of He (24.5eV), Ar, (15.68eV] 2 (14.6eV) and N CO2 (13.8eV), it is felt that He inhibition of plasma best. The customer can choose the suitable green laser pointer according to the needs and tastes.

sometimes the laser beam self-focusing phenomenon

green laser pointer can be commissioned and adjusted for the customer
Wavelength 10.6μm CO2 laser welding of the absorption rate of two orders of magnitude higher than the absorption of the YAG laser wavelength of 1.06μm. Absorption rate, the different wavelengths

of laser-produced plasma power density required threshold. YAG laser-produced plasma threshold power density is about two orders of magnitude higher than the CO2 laser. In other words, the CO2

laser processing, easy to produce plasma and its impact, while a smaller impact of YAG laser processing, plasma. Laser beam through the plasma, the change of the absorption and focusing conditions,

sometimes the laser beam self-focusing phenomenon. Plasma absorption of light can be transmitted through different channels to the workpiece. The high performance laser module of green laser pointer is also critical to the quality.
Wall focusing effect generated allows the laser to maintain a high power density within the hole, and further heating the melt material. Important for the laser welding process, the laser power

density in the remaining holes at the bottom of it must be high enough to maintain the bottom of the hole high enough temperature to produce the necessary vapor pressure to maintain a certain depth

of the hole. Focusing effect appears to generation and wall of the pinhole effect, can dramatically change the process of laser interaction with matter, when the beam to enter the holes, the holes

is equivalent to a light absorbing black body, and greatly increase the energy absorption rate. Purifying effect of purifying effect of the CO2 laser welding, the weld metal of harmful substances

reduced or mixed with the material to reduce the phenomenon.
Defocus amount of welding quality. Laser welding is usually away from the fuss about because of the 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. According to the theory of geometrical optics, when positive and negative away from the focal plane with the welding plane equidistant,

corresponding to approximately the same power density on the plane, but the weld pool shape actually. Negative defocus, the availability of greater penetration, which is related with the formation

of the molten pool. Solution heat treatment the steel is heated to 1050 to 1150 ℃, homogeneous single-phase austenite, and then rapid cooling and high-temperature supersaturated

solid solution state remains to room temperature.

The use of robots, the wrench of the clamp grasping device must be large enough in order to seize a large workpiece clamp grasping device must be equipped with smart sensors (sensory and visual), the height used to detect stack components. The solution is the use of epoxy carbon fiber to make the clamp grasping device, with many small suction cups and miniature inductive sensors.

Therefore, to develop the TFT-LCD related materials has become the common and urgent tasks of the industry. Nano-information materials is an important part of nano-materials, and electronics, optoelectronics and communications technology, computer technology is closely related. February 2000 published by the United States National Nanotechnology Initiative, said: "nanostructures will nurture a revolution in the IT hardware, similar 30 years ago that a microelectronics revolution that a revolution in semiconductor Electronics replaced the vacuum tube electronics; the coming of a nanoelectronics revolution, millions of times more the Supermicro transistors and memory chips will improve the speed and efficiency of the computer.
Self-organized quantum dot lasers. Since 1971 molecular beam epitaxy grown GaAs potential well, and AlxGa1-xAs after the barrier of quantum wells, quantum confinement effects in quantum wells has been extensive and in-depth study, and on this basis developed many new high-performance optoelectronic and microelectronic devices, such as: heterojunction lasers, quantum well lasers, optical bistable devices, infrared detectors, high electron mobility transistors and heterojunction bipolar transistors, have been entered the practical stage, and some have been formed products. A large number of semiconductor lasers used in fiber-optic communications, CD-ROM access, monitor, etc.. As the use of the quantum confinement effect and bandgap engineering design.
The reason is that the quantum dot preparation process is not perfect. In order to improve the performance of quantum dot lasers, but also the need for manufacturing technology to make significant improvements in-depth study of the physics of quantum dots. Silicon-based materials. Silicon is the main material for microelectronic devices, low prices, devices and integrated circuit processing technology is mature, with the incomparable superiority of other semiconductor materials. However, silicon is an indirect band gap semiconductor, its luminous efficiency is very low. If you do use silicon light emitting devices, and on the same chip with other optical components, microelectronic devices, to achieve optoelectronic integrated. Will undoubtedly show that the communications, computer and other far-reaching impact. The laser pointer can burn the match or other materials.
For example, the time lag caused by the electrical interconnection between the devices has become a bottleneck for the development of ultra-LSI. Use optical interconnects to replace currently used by the electrical interconnection of integrated circuits can greatly improve performance, increase computer speed. 1990 Hom Han (LTCanham,) found that the luminescence of porous silicon, has opened a new prospect for optoelectronic integration on silicon.
