laser pointer is wrapped with environment-friendly copper

 laser pointer is the good choice for superior and fashionable business gifts.
Splitting the laser beam is easy to implement, can be used semi-lenses, mirrors, prisms, mirrors and other optical components scan time and space partitioning, to achieve more symmetrical while welding. Multi-wavelength laser brazing 1.06um laser as a heat source, available optical fiber transmission, it can be difficult in the conventional way of processing parts of welded, good flexibility. Focus is good, easy to implement automated multi-station devices. Physical metallurgy of laser deep penetration electron beam welding process is very similar, namely, the energy conversion mechanism is through the "hole" structure to be completed. At sufficiently high power density beam irradiation, the materials have evaporated to form holes. laser pointer is a kind of top grade green ray laser pointer.
This is full of holes like a blackbody of steam, almost all the energy absorption of incident light, the hole cavity equilibrium temperature of 25,000 degrees. From this high-temperature heat transfer out of the hole wall cavity, so that the hole surrounded by metal melting chamber. Holes filled beam irradiation in the wall material continuous high temperature steam generated by evaporation, the walls of the hole surrounded by molten metal, liquid metal that is around four weeks of solid materials. Outside the hole wall surface tension of liquid flow and the parietal cavity continuous with the pore pressure generated by the steam rally and maintain homeostasis. Beam continuously into the holes, holes in a continuous flow of foreign material, with the beam moves, the hole is always in steady-state flow. laser pointer is wrapped with environment-friendly copper.
That is, holes, and the molten metal around the hole wall of the forward speed of the beam with a leading forward, remove the molten metal fills the hole left by the gap and subsequently condensed, so the formation of the weld. Deep penetration of the laser impact factors include: laser power, laser beam diameter, material absorption rate, welding speed, shielding gas, lens focal length, focus position, laser beam position, weld start and end point of the laser power gradually rise , gradually decreased control. Characteristics: (1) high aspect ratio. Because the molten metal around the cylindrical steam chamber and extends to the formation of the workpiece, the weld becomes deep and narrow. (2) minimum heat input. Because the source chamber temperature is high, the melting process occurs very fast, very low heat input workpiece, heat distortion and heat affected zone is very small. Looking at laser pointer , you can immediately know the wrapping material.
