Laser Welding Heads

The laser welding head focuses a high-intensity laser beam onto the workpiece to join two or more pieces of metal together. It’s highly precise and efficient, widely used in many industries such as automotive and aerospace.

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:

  1. 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.

  2. 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.

  3. Sensor: Some laser welding heads may include sensors to monitor the welding process and provide feedback on the quality of the weld.

  4. 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.

  5. 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.
