Fiber laser welding machine and YAG laser welding machine working principle!

Fiber laser welding machine and YAG laser welding machine have different working principles, but both are based on laser technology. Here are their working principles:

Fiber laser welding machine working principle:

Fiber laser welding machine uses high-energy laser beam to irradiate the edges of the two parts to be welded, and the output energy heats and melts the metal. Under the action of the laser beam, the molten material cools rapidly and eventually becomes one. This welding method is fast, filler-free, has a large melting depth, small thermal deformation, and can achieve automated welding.

YAG laser welding machine working principle:

YAG laser welding machine uses YAG crystal rods and xenon lamps to generate lasers using laser power supplies and various lenses in the optical path design. Specifically, the pump source emits incident light of a specific wavelength, which causes the working material to invert the number of particles, releases lasers through energy level transitions, and amplifies and shapes the laser energy to form a usable laser beam. This welding method uses the principle of laser oscillation and is suitable for welding a variety of materials and precision parts.

Although the working principles of fiber laser welding machine and YAG laser welding machine are different, they both use the high energy density characteristics of laser to achieve efficient and precise welding. Fiber laser welding machine transmits laser through optical fiber and is suitable for welding thin-walled materials and precision parts, while YAG laser welding machine generates laser through YAG crystal rod and is suitable for welding a variety of materials and complex structures.
