A laser welding head typically consists of several components that work together to focus and deliver the laser beam to the workpiece. These components may include: Optics: The laser beam passes through a series of lenses and mirrors that focus and shape the beam to the desired size and shape for the welding process. Nozzle: A nozzle or gas delivery system is used to deliver a shielding gas (such as argon or nitrogen) to the weld area to prevent oxidation and contamination. Sensor: Some laser welding heads may include sensors to monitor the welding process and provide feedback on the quality of the weld. Cooling system: The laser welding head generates a significant amount of heat, so a cooling system is typically included to keep the components of the welding head from overheating. Mounting mechanism: The laser welding head is typically mounted on a robotic arm or CNC machine, which controls the movement of the welding head during the welding process.
