Laser welding machine, according to their working methods, they are divided into automatic laser welding machines, laser spot welding machines, and optical fiber laser welding machines. The principle is to use the high-energy laser pulse emitted by a laser welding machine to locally heat the material in a small area, guide the internal diffusion of the material through heat transfer, and melt the material to form a specific molten pool to achieve the purpose of welding.
Laser welding machine are different from traditional welding machines. Due to the enormous heat input, traditional welding methods inevitably bring about problems such as distortion and deformation of the workpiece. Laser welding is low in noise, high in efficiency, smokeless and dustless, and can achieve beautiful heat conduction welding of welds, as well as deep penetration welding with high welding strength and high welding speed. For example, the appearance of elevators, kitchen utensils, and automotive equipment requires a very beautiful, smooth, and deformation free welding effect. The application of laser welding in sheet metal manufacturing is becoming more and more common.
In addition, laser welding machines determine the speed and depth of welding based on individual needs, which can greatly improve welding efficiency and stability. Laser welding machines are increasingly widely used in modern industry, requiring a large number of subsequent processing methods to reduce workpiece distortion and deformation, thereby increasing cost.
In modern sheet metal manufacturing, the quality requirements for welding strength and appearance effects vary depending on the product. However, laser welding machine has small heat input and very small Heat-affected zone, which can effectively improve the quality of welding products and reduce the time of follow-up work. However, some internal structural components or parts that require subsequent spraying have high requirements for welding strength and welding speed. Especially for components with high added value and high requirements for welding quality, it is required to complete them without or with little follow-up processing.
