Galvanometer laser welding is a high-efficiency welding method that transmits high-energy laser beams by galvanometer scanning control, that is, laser radiation heats the surface of the workpiece, and changes the laser energy and surface heat by adjusting parameters such as the width, peak power and repetition frequency of the laser pulse. The workpiece is melted to form a specific molten pool by diffusing heat to the inside. Due to its unique advantages, it has been successfully applied to the welding of micro and small parts. Jinhaichuang 3D laser galvanometer welding has the advantages of high power, wide format and visual tracking, and has the technical ability to perform laser welding and one-time forming of complex arc surfaces such as titanium alloy components.
Laser deep penetration welding generally uses continuous laser beam to complete the connection of materials. When the power density is greater than 105~107W/cm2, the metal surface forms a faster welding speed and a larger aspect ratio, and completes the energy conversion through the "small hole" structure. Mechanism, the hole and the molten metal surrounding the hole wall move forward with the advancing speed of the leading beam, the molten metal fills the gap left after the hole is removed and condenses to form a weld.
Main application areas
Equipment manufacturing: Galvo laser welding is transforming to high power and intelligence. Tailored laser welding technology has been widely used in car manufacturing. Welding of ultra-thin plates below 100 microns cannot achieve fusion welding, but it can be completed through specific YAG laser welding. , showing the bright future of laser welding.
Powder metallurgy: Powder metallurgy materials have special properties and manufacturing advantages, so they are replacing traditional smelting materials in the manufacturing of automobiles, aircraft, and cutting tools. Laser welding can improve welding strength and high temperature resistance, and solve problems with other parts. connection problem.
Electronics industry: laser welding has a small heat-affected zone, rapid heating concentration, and low thermal stress, so it shows unique advantages in integrated circuits and semiconductor packaging. In the development, laser welding has also been applied.
Biomedicine: Compared with the traditional suture, the laser welding method has the characteristics of fast anastomosis, no foreign body reaction during the healing process, and the repaired tissue at the welded part grows according to its original biomechanical shape. This technology will be used in future biomedicine. Wide range of applications.
