Welding technology has a great impact on the industrial production of a country, especially in some high-tech fields. In addition to these high-tech fields, it is a must for the welding of automobile gears. The technology used, do you know why gears use laser welding technology? What are the benefits of doing this?
First of all, before we understand this problem, we need to make a simple understanding of laser welding. Looking at the name, we can get some key information. It is different from ordinary arc welding. Ordinary welding uses electric arc for welding, while laser welding uses laser for welding. When welding, we directly use laser to irradiate the place to be welded. Continuous irradiation will heat the welded workpiece. After heating, the atoms will slowly combine. Starting from the atomic aspect, the welded object has high stability. It is a permanent connection process. When laser welding is used, the temperature deformation of the workpiece is very small. Compared with ordinary electric welding, it has high energy, is not easy to deform, and is affected by welding. The place of welding is very limited, the welding is very fast, the surface of the weld can be used as long as it is formed, the weight of the whole workpiece is very light, and the processing method is relatively simple. In the automotive field, the gear of the gearbox is made smaller and smaller, and the accuracy requirements are higher and higher. If the laser technology is used, it can control the welding deformation of the gear in a reasonable range. It can enhance the service life of the vehicle and reduce the failure rate of the vehicle.
