Application of laser welding machine for mobile phone nut stud

by:J&D WATER     2020-02-26
With the rapid growth of China's economy and the substantial improvement of people's living standards, people's demand for mobile phones is also increasing day by day, which also drives the development of the mobile phone nut Stud market. Mobile phone nuts are usually made of SUS304 stainless steel, which has the characteristics of excellent antirust performance and high mechanical strength. The main function of the mobile phone nut is to connect the plastic parts with the metal parts, or connect the metal parts with the metal parts to play a fastening role, mobile phone stainless steel nuts are generally connected to mobile phone stamping parts or other workpieces by means of riveting, riveting, etc. However, the rotary riveting method is very uneconomical, and the pressure riveting method is easy to have deformation and other effects on other parts, while the laser welding machine has the advantages of high energy density, high welding efficiency, small heat influence and small deformation, etc, the non-contact welding method is adopted, which is not affected by the size and appearance of the workpiece, and can realize long-distance rapid welding, and is very suitable for mobile phone nut welding. The application of mobile phone nut stud laser welding machine is a welding technology with high laser energy and concentrated fixed points. It uses laser deposition welding to spread surface heat to the inside by controlling the width and energy of laser pulse, parameters such as peak function and repetition frequency make the workpiece melt to form a specific molten pool to achieve the welding effect. The stainless steel laser welding machine is fast and energy stable, and can completely achieve the dense spot and fast welding speed of mobile phone nut column laser welding, ensuring the strength and welding efficiency of mobile phone laser welding.
