The quasi-continuous laser precision welding research and development platform utilizes high-energy laser pulses to locally heat materials in small areas. The energy from the laser radiation diffuses into the material through thermal conduction, melting the material and forming a specific molten pool to achieve the welding purpose. It can solve the technical challenges in the process, equipment, and control technology of high-end sheet and strip material welding. It has a wide range of applications in aerospace, microelectronics, 3C (computers, communications, and consumer electronics), medical, and sensor fields.
