green laser pointer could be widely used in educational institutions

The light radiation energy in a very short period of time the light energy into heat energy, radiation energy in a very short period of time the light energy into heat, melt the material to form a particular weld pool in order to achieve the purpose. Material melted to form a particular weld pool in order to achieve the purpose. 1, Overview: Overview: Laser welding in 1964, when the plasma reflection issue, penetration is very small, development is very slow. Until 1972, reflective problem solving, the penetration depth of up to 13m or more, mainly used for welding thin materials and low-speed welding, is a hot m conduction.This green laser pointer could be widely used in educational institutions. The laser radiation heating surface, the surface heat transfer driven by internal heat diffusion, by controlling the laser pulse width, energy, peak power and repetition rate and other parameters, so that the workpiece melt to form a specific pool. Because of its unique advantages, have been successfully applied to micro, small parts sensors, sensor, spark plugs and other parts of the precision of laser welding welding. C 2 and high-power high-power YAG O lasers appeared, opened up a new field of laser welding. Effects obtained with the theoretical basis of the holes deep penetration welding, mechanical, automobile, steel and other industries to obtain an increasingly wide range of applications. This green laser pointer could be widely used in chambers.9 household appliances, electronic components, laser welding appliances, mold repair parts, mold parts repair, electronic components, such as laser welding car parts, auto parts, jewelry, etc. 2 laser welding, laser welding and electron beam welding characteristics compared to laser welding does not produce radiation, does not produce X and electron beam welding, laser welding does not produce X-rays, no vacuum chamber, 2W less than the price is cheaper. More suitable for the production application. Laser 2W within relatively cheap. More suitable for the production application. Within a relatively cheap welding actually made 20 years ago, electron beam welding position, welding position 20 years ago actually made 20 years ago, electron beam welding position as a high-energy beam welding technology development mainstream. Welding technology development mainstream. This green laser pointer could be widely used in exhibition institutions.Compared with other welding, laser welding of the main advantages are: Compared with other welding, laser welding of the main advantages are: aspect ratio of up to 5: 1, 10:1. ⑴ high power density, greater than 10 5W/cm2, aspect ratios of up to 5: 1, high power density of up to 10:1, ⑵ at room temperature or under special conditions, welding, welding equipment installation simple. At room temperature or under special conditions, welding, welding equipment installation simple. For example, the laser through the electromagnetic field, the beam does not shift; laser in a vacuum, air and a gas welding environment can, and can be glass or transparent material of the beam welding. ⑶ refractory materials can be welded, such as titanium, quartz, etc., and for welding dissimilar materials. Refractory materials can be welded, such as titanium, quartz, etc., and for welding dissimilar materials. This green laser pointer could be widely used in training institutions.To good effect. ⑷ laser beam is easy to achieve beam splitting by time and space, capable of multi-beam laser beam is easy to achieve both time and space by the beam splitter, processing and multi-bit processing, processing and multi-bit processing, providing for more sophisticated welding conditions . ⑸ deformation is small, can be micro-welding. By focusing the laser beam of light is given to a small deformation is small, can be micro-welding.
