The daily use of green laser pointer is always drawing much attention

Under the control of the computer, through pulsed laser discharge, in order to repeat the high-frequency pulsed laser with output controlled to a certain frequency, a certain pulse width of the beam, the pulsed laser beam through the optical transmission and reflection and through the focusing lens group to focus on the processing of objects on the surface, forming a small, high energy density spot, to be processed near the focal spot is located, transient high-temperature melting or gasification, processing materials. A high-energy laser pulse instantly put a small hole surface sputtering, under computer control, the continuous relative movement dot laser processing head and the material being processed by the pre-painted graphics, object processed into the desired shape. The manager sends   green laser pointer    to the customer as the free sample.
Cutting, wave and beam coaxial airflow emitted from the cutting head, blow melting or gasification of the material from the bottom of the incision (Note: If the gas blowing and cutting material thermal efficiency response, this response will provide cutting The additional energy required; airflow cooling the cutting surface, reduce the heat-affected zone and to ensure the role of the focusing mirror is not contaminated). Compared with the traditional plate processing, laser cutting with a high cut quality (narrow kerf width, the heat affected zone is small, smooth incision), high cutting speed and high flexibility (can be cut any shape), a wide range of materials the advantages of adaptability. The laser welding technology of laser welding is one of the important aspects of laser material processing applications. The fantastic laser performance of    usa green laser pointer     can be shown to the music.
The welding process is a thermal conductivity type, the laser radiation heating the surface, the surface heat transfer through the heat transfer-oriented internal diffusion parameters by controlling the laser pulse width, energy, peak power and repetition rate of the workpiece melt, the formation of specific bath. Because of its unique advantages, have been successfully used in the micro, small parts welding. The emergence of high-power CO2 and high-power YAG lasers, has opened up new areas for laser welding. To obtain a deep welding, to the effect of holes as the theoretical basis of the increasingly widely used in machinery, automobile, steel and other industrial sectors. Compared with other welding techniques, the main advantages of laser welding: laser welding speed, depth, small deformation. Room temperature or under special conditions, welding, welding equipment device is simple. The daily use of green laser pointer is always drawing much attention.
For example, the laser through the electromagnetic field, the beam will not be offset; laser welding can in the air and a gas environment, and through the glass or transparent material on the beam welding. Laser focus, high power density welding of high-power devices, the aspect ratios up to 5:1 up to 10:1. Welding of refractory materials such as titanium, quartz, and welding the opposite sex material to good effect. Just like the distinct nature of both copper and tantalum materials are welded together, the pass rate of almost 100%. Micro-welding. The laser beam focus is given to a small spot and can precise positioning can be applied to the welding of the automated production of large quantities of micro, small components. The technology improvement meeting of   green laser pointer      will be held next morning.
For example, the IC lead, watch springs, CRT electron gun assembly and so on the use of laser welding, not only production efficiency, high-and heat-affected zone, the solder joint non-polluting, greatly improving the quality of welding. Welding can be difficult to close the site, the implementation of long-distance non-contact welding, and has great flexibility. YAG laser technology, fiber optic transmission technology, a wider range of promotion and application of laser welding technology. 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 heat treatment technology (laser phase transformation hardening, laser hardening) laser heat treatment is the use of high power density of laser beam on the metal surface treatment method. The purchase of   green laser pointer      has the strict management requirements.
