The quality assurance group of china laser pointer will arrive tomorrow

Pulsed laser welding. Pulsed laser spot welding similar to each laser pulse to form a solder joint in the metal, mainly used in miniature, precision components and microelectronic components welding. Pulsed laser welding process and parameters are as follows. Heat conduction welding heat conduction laser welding, the laser radiation heating surface, the surface of the heat through the heat transfer-based internal diffusion, by controlling the laser pulse width, energy, peak power and repetition frequency of laser parameters, so that the workpiece melting, formation of a specific pool . As the heating laser welding speed, solder a small, narrow weld and heat affected zone. The parameter in the drawing ofchina laser pointeris important.
So welding distortion, high precision, good quality welding, currently in the automotive, aircraft and other representative of the industrial manufacturing sector, has largely adopted this approach. Laser welding, and the welded materials because they do not touch, they are able to weld difficult to close the site, but also through the transparent material of the wall or even underwater welding. It can direct insulation and conductor materials, welding, soldering non-ferrous metals can also be welded dissimilar metals. In general, laser welding without other complex materials, auxiliary equipment and the environment. The lower price can be provided forchina laser pointerif the order is large enough.
Laser deep penetration laser welding generally use deep connection to the process of continuous laser beam, the physical metallurgy and electron beam welding process is very similar, namely, the energy conversion mechanism is accomplished through the hole structure. At sufficiently high power density beam irradiation, evaporation materials have generated holes. This is full of holes like a blackbody vapor, absorb almost all incident beam energy, the hole cavity to reach equilibrium temperature of about 25000 ℃, high temperature heat from the cavity wall pass out of the hole, so that the hole surrounded by molten metal around the chamber. Filled holes in the wall material under the beam irradiation generate continuous high temperature steam evaporation, small holes surrounded by walls of molten metal, liquid metal is surrounded by solid material (the surface in most conventional conduction welding and laser welding process, the energy deposition in the first Department of the workpiece surface, and then transported to the interior by conduction). The quality assurance group of china laser pointer will arrive tomorrow.
Hole wall and the outer parietal surface tension of liquid flow and pore pressure cavity continuous 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. That is, holes, and the molten metal around the hole wall of the forward speed of the beam with a leading forward, filled with molten metal left after removal of the gap opened and subsequently condensed, so the formation of the weld. The process all of this happened so fast, so that the welding speed can easily reach several meters per minute. Laser welding, laser welding equipment components. The director will report the result of production supervision of green laser pointer to the manager.
Currently, lasers for industrial processing, mainly solid-state lasers and gas lasers into two categories, according to the output can be divided into pulsed laser and CW lasers. Either welding equipment, most of their composition is similar to Figure 3-6 is a block diagram of laser welding equipment. The performance characteristics of different CO2 laser shown in Table 3-2. Lasers. CO2 laser under way into low-speed axial flow type air-cooled, high-speed axial flow type, cross-flow type and closed early. Beam transport and focusing system, also known as external optical system used to transmit and focus the laser beam on the workpiece, the end of the installation provide protection or auxiliary air welding torch or cutting torch. The great manufacture ability ofchina laser pointeris the most remarkable characteristic of the new manufacture base ofchina laser pointer.
