Do you know the difference between fiber laser cutting machines and fiber laser welding machines

Fiber laser cutting machines and  fiber laser welding machines both rely on  fiber lasers to complete processing tasks, but their functionality is greatly different. So, what is the difference between the two? Below, Prima fiber laser manufacturer will introduce it to everyone separately!

Firstly, we need to understand how  fiber laser cutting machines complete the cutting function.

A  fiber laser cutting machine is a horizontal  fiber laser beam emitted by a  fiber laser that passes through 45 ° deg; The total reflection mirror becomes a vertically downward  fiber laser beam, which is then concentrated through a lens to form a very small spot at the focal point. The  fiber laser power density at the focal point is as high as 10 ^ 6-10 ^ 9W/cm ^ 2. The workpiece at its focal point is illuminated by a high-power density  fiber laser spot, which can cause 10000 deg; The high temperature above C causes the workpiece to vaporize in an instant, and then cooperates with the auxiliary cutting gas to blow away the vaporized metal, thereby cutting the workpiece into a very small hole. With the movement of the CNC machine tool, countless small holes connect to form the shape to be cut. Because the frequency of  fiber laser cutting is very high, each small hole connection is very lubricated, and the resulting product has a high smoothness.

However,  fiber laser welding machine is a new type of welding method, mainly used for welding thin-walled materials and fine parts. It can complete spot welding, butt welding, overlap welding, seal welding, etc., with high aspect ratio, small weld width, small heat affected zone, small deformation, fast welding speed, flat and beautiful weld seam, no need for treatment or simple treatment after welding, high weld quality, no pores, accurate control, small gathering light points, and high positioning accuracy, Easy to complete automation. It uses high-energy  fiber laser pulses to heat parts of the data in small areas, and the energy radiated by the  fiber laser is directed towards the internal diffusion of the data through heat transfer, melting the data and forming a specific molten pool.

I believe that through the above introduction, everyone will have a certain understanding of the two types of  fiber laser equipment! In fact, the principle of a  fiber laser welding machine is similar to that of cutting, but the purpose it achieves is the opposite. Its main secret lies in the power of the  fiber laser. Based on experience, the two can actually achieve symbiosis on the same machine, with only slightly different programming and different  fiber laser powers called.
