YAG Fiber Transmission Energy Feedback 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 enterprise manufacturing 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 industrial laser welding system 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. The negative energy feedback technology allows the laser output energy with good repeatability, simply put, is to ensure that each output of the laser energy stability, which can be effective in reducing the defect rate of the product.
