The definition and working principle of an industrial laser welding machine

Laser welding is a welding technology used to join pieces of metal and thermoplastic using a laser beam. This method is a method of heating and melting the welding area with a laser beam, which is suitable for narrow or deep welds and extremely fast welding. Laser welding is compatible with a wide range of materials and provides precise connections. Also, the process of welding using a laser welding machine is a method of melting and connecting workpieces using laser energy. Laser welding is possible because the energy of the laser is very high, but more accurate, the energy density is very high because the laser energy is extremely high at one point. Based on this principle, laser welding is being used in various industries.

Laser welding provides precise work and fast welding speed, and is frequently used in the automotive industry, jewellery, metal processing, etc. Also, since laser welding uses a laser, it has the great advantage of not surprising other areas. Laser welding is classified into various types according to the regulations of the laser beam. Thermal conduction welding is a method in which the material conductive melts in the surface layer due to the low output density of the laser beam and the long laser irradiation time. In comparison, keyhole welding removes a deeper, narrower weld, and the molten material fills the keyhole to form a weld bead. Laser welding is using various laser types, including solid-state lasers, gas lasers, and fiber lasers. Laser welding is a precise welding technology using a laser beam, and is used in various industries.
