The surface treatment of green laser pointer plays a decisive role inthe manufacture

The high output power of a lens focusing the laser, the resulting energy density of sunlight hundreds of times. Laser welding using a laser beam of excellent directivity and high power Mody density characteristics of the work. The laser beam is focused through the optical system in a small area, welded at the formation of an energy highly concentrated heat source area within a very short time, so that the solder material melts and forms a solid solder joint and the weld. Commonly used in laser welding of two kinds: the pulsed laser welding and continuous laser welding. The former is mainly used for single-point fixed continuous and thin material welding. The latter is mainly used for welding and cutting large pieces of thick. The surface treatment of green laser pointer plays a decisive role in the manufacture.
Laser welding characteristics of the processing methods. Non-contact processing, without pressure on the workpiece and the surface treatment. Solder joints, high energy density, suitable for high speed machining. Welding a short period of time, both on the outside and the heat-affected, but also the thermal deformation and heat affected zone is small, and is particularly suitable for processing high melting point, high hardness, specialty materials. Do not need to fill the metal, does not require a vacuum environment (in the air), not like the electron beam in the air as the danger of X-ray. Compared with exposure to welding process. Electrodes, tools and other wear and tear. Processing noise pollution to the environment. Small parts can be processed. In addition, the welding can also be carried out through the transparent material of the wall. The manager and the customer are negotiating the price ofgreen laser pointer.

When the low power density and longer exposure time while welding pieces of thin, usually mainly to the melting heat transfer mechanism. On the contrary, is based on deep penetration of the melting mechanism to main. Process characteristics and its influencing factors. The laser input energy density. The method of adjusting the laser energy density: the adjustment of the laser output energy (adjust the excitation voltage). Adjust the spot size (to regulate the exit focal length). Change the energy distribution in the spot (to change the fiber type: the peak-shaped output type - the GI optical fiber, the trapezoidal output type-SI type fiber). The worker should pay attention to self protection during manufacture process ofgreen laser pointer.
Change the width of the radio pulse and waveform. Most metals in the laser exposure, the majority of laser energy reflected from the welding process begins the moment a corresponding increase in beam power. Using pulsed laser seam defended by two arts, you can access arc plate to ensure the quality and consistency of the entire welding segment. When the melt or vaporize the metal surface, the reflection rate is decreased rapidly. The main factors affect the material of the laser beam absorption. Laser absorption rate of the metal materials at room temperature below 20 ℃; when the metal temperature reaches the branded point melting and gasification, the absorption rate increased to 40 ~ 50%. The innovative design of green laser led greatly improve the quality ofgreen laser pointer.
