Galvo Scanner Laser welding is an efficient and precise welding method for transmitting high energy laser beam by means of vibration mirror scanning control. Laser radiation heating workpiece surface, by adjusting the laser pulse width, peak power and repetition frequency and other parameters to change the laser energy, surface heat through the heat conduction to the internal diffusion, so that the workpiece melting into a specific molten pool. Because of its unique advantages, it has been successfully applied to the precision welding of micro and small parts.
3D Laser Galvo Scanner welding is at the advanced level in the world, with the advantages of large power, wide breadth and visual tracking, and has the technical capability of laser welding and forming of a complex arc surface for titanium alloy components. Laser deep penetration welding generally uses continuous laser beam to complete the material connection, when the power density is greater than 105~107w/cm2, the metal surface forms a faster welding speed and a larger depth-width ratio, and a "small hole" structure completes the energy conversion mechanism, and the small hole and the molten metal around the hole wall move forward with the leading beam, The molten metal fills the holes and leaves the pores and condenses to form the weld.
