3-Axis Energy Feedback Fiber Transmission Laser Welding Machine

Energy Feedback Galvanometer Laser Welding Machine
The energy feedback technology enables the machine to control laser output power fluctuations within 3%, ensuring the stability of laser output power. This capability enhances welding repeatability, reduces the production of unqualified products, and ultimately saves costs. Real-time energy negative feedback controlling system to control the energy accurately.

Energy Feedback Fiber Transmission Laser Welding Machine

The YAG fiber transmission laser welding machine can realize the splitting of time and energy. It can process multiple beams at the same time, which provides conditions for more precise welding. Real-time energy negative feedback ensures stable laser output energy.

The working principle of the energy feedback laser welding machine is an energy detection device is added to the output end of the laser to detect the size of the output laser energy and feedback the signal to the control end in real time. Then compare with the set energy to form a closed-loop control system to achieve the purpose of accurately controlling the laser energy output.

Advantages of Energy Feedback Galvanometer Laser Welding Machine:

  • Equipped with an automatic energy detection and compensation system, the energy output is more stable, and the solder joint size is guaranteed to be consistent.
  • The fiber laser in the energy feedback fiber transmission laser welding machine, after the optical fiber output collimation and focusing, can weld the welding parts in multiple or multi-points, which has the advantages of good beam quality, even and small spot, convenient installation and movement, etc.
  • Stable operation: under the condition that the welding materials and models remain unchanged, setting suitable welding parameters can be used for a long time.
  • Energy feedback technology can make the laser output energy has a good repeatability, in simple words, is to ensure that the output of laser energy is stable, which can effectively reduce the failure rate of products.
  • Multi-beam simultaneous processing, welding speed is significantly increased. Enable customers to complete processing orders efficiently and with high quality in the shortest time.
  • Welding depth to width ratio up to 10:1, smooth and beautiful welding joints, flat and no air holes. No treatment is required after welding, or only some simple processing is needed.
  • Specialized machines can be customized according to customers’ requirements.
