How to ensure quality and consistency of laser welding. Laser welding is a high-temperature melting materials by laser to make a permanent connection, and processing technology with a set of functional structure. In recent years, almost all electronic products, such as computers, televisions, mobile phones, digital cameras, and many electronic components, etc., to varying degrees in the manufacturing application of laser welding technology. Laser welding has penetrated into all areas of manufacturing, a direct impact on product quality, reliability and longevity, as well as production costs, efficiency and speed of market reaction. The manager wants to know more about the need analysis of green laser pointer .
How to ensure quality and consistency of product laser welding, laser welding of high-volume production process, production management process is a very important issue. In general, the factors affecting the effect of laser welding can be summarized as the following three options: Welding material selection. Laser welding machine of choice. The choice of the processing table. Laser welding effect and optical properties of the material being processed, physical characteristics and mechanical properties. Optical properties: the reflectivity of the material, the absorption rate, transmittance; physical properties: thermal conductivity, thermal diffusivity, density, specific heat, heat capacity, melt viscosity, vaporization temperature; mechanical properties: machining accuracy of the stress intensity, material weldability, the workpiece cleanliness. The charger of the rechargeable battery of green laser pointer will be delivered together.
First determine the processing of materials, especially when two or more different materials, welding process, refer to the relevant literature to determine the material can not be reliable soldering (Table 1 presents the YAG laser welding characteristics of different materials can be used as reference) In addition, the reflectivity of different materials for different laser wavelengths are not the same (see Figure 1), the higher the reflectivity,
