The working condition of warehouse of green laser pointer is better than before

 Hole wall outside the liquid flow and parietal surface tension and hole cavity continuous steam pressure stalemate and maintain homeostasis. Beam continuously into the holes, the holes outside continuous flow of material in the beam mobile holes is always in the stable state of the flow. The working condition of warehouse of green laser pointer is better than before.
That is, the holes and around the hole wall of the molten metal to move forward with the leading beam forward speed, the molten metal fills the gap left by the holes away and followed by condensation, so the formation of weld. Factors. Include: factors that affect the laser deep penetration laser power, laser beam diameter, material absorption rate, welding speed, shielding gas, lens focal length, focus position, the location of the laser beam welding starting and ending point of the laser power is gradually l gradually decreased to control. Laser deep penetration characteristics and advantages. Characteristics: (1) high aspect ratio. Because the molten metal is formed around a cylindrical high-temperature steam chamber and extends to the workpiece, the weld becomes deep and narrow. (2) the minimum heat input. The warehouse stores a large mount of parts and components of green laser pointer .
Because the high temperature of the source chamber, the melting process happened so fast, input workpiece low in calories, heat distortion and heat affected zone is very small. (3) high density. Full of high-temperature steam Kong Youli in the welding bath mixing and gas to escape, leading to generate stomatal penetration welding. The high cooling rate after welding, easy to weld miniaturization. (4) strong weld. (5) precise control. (6) non-contact, atmospheric welding process. Advantages: (1) of the focused laser beam than conventional methods with much higher power density and welding speed, the heat-affected zone and deformation are small, and can also be welded titanium, quartz and other hard brazing materials. (2) because the beam is easy to transfer and control, but also does not require frequent replacement of the welding torch, nozzle, significantly reducing downtime auxiliary time, so the charge coefficient and production efficiency. The worker is carefully operating the machine of processing green laser pointer .
