[0002] The swing bracket is a specially designed bracket, and its main feature is that it can swing or rotate. During the manufacturing or assembly process of the swing bracket, welding is usually required to ensure its structural strength and stability. Welding can increase the connection strength between the components of the swing bracket, so that it can withstand various external forces and loads, and thus a laser welding machine is required to weld it; Laser welding machine is a machine that uses high-energy laser pulses to weld materials. It uses the energy of laser radiation to locally heat the material in a small area, so that the material melts to form a specific molten pool to achieve the purpose of welding. It can realize various welding methods such as spot welding, butt welding, lap welding, and sealing welding. It is suitable for welding thin-walled materials and precision parts.
