Laser welding 2025

　　Laser welding is a welding method that uses a high-energy density laser beam as a heat source. Below is a brief introduction to laser welding:

　　The working principle of laser welding is to focus the laser generated by the laser onto the workpiece, converting light energy into heat energy, which then melts the material to form a weld seam. Depending on the power density, laser welding can be divided into two types: conduction welding and deep penetration welding. Laser welding has the characteristics of high efficiency, precision, small heat affected zone, and strong applicability. The welding speed is fast, the production efficiency is high, and it can greatly improve the operation speed of the production line. At the same time, the laser beam has a strong focusing ability, which can achieve high-precision welding and reduce welding defects.

　　In addition, laser welding also has advantages such as small welding deformation, welding can be performed at room temperature or under special conditions, welding of refractory materials and dissimilar materials, and welding of difficult-to-access parts. However, laser welding also has some disadvantages, such as the requirement for high workpiece assembly accuracy and the high cost of lasers and related systems.

　　In general, laser welding is an advanced welding technology with broad application prospects in modern industrial manufacturing.
