Laser machine laser welding distance

Laser welding machine, also often referred to as laser welding machine, laser welding machine, is a laser material processing with the machine, according to its mode of operation is divided into laser mold burner, automatic laser welding machine, laser spot welding machine, fiber optic transmission laser welding machine, light welding is the use of high-energy laser pulses on the material for a tiny area of the local heating, laser radiation of the energy through the heat conduction to the internal diffusion of the material, the material will be The laser radiation energy spreads to the inside of the material through heat conduction, melting the material and forming a specific melt pool to achieve the purpose of welding. The welding distance can be up to 3mm.
