A fiber laser welding machine with a wire feeder is an advanced welding system that combines the precision of fiber laser technology with the flexibility of filler material addition. This setup is commonly used in applications requiring high-quality welds, such as in automotive, aerospace, and precision manufacturing.
How It Works:
Laser Generation:
The fiber laser generates a high-intensity laser beam (typically 1µm wavelength) using doped optical fibers and diode pumps.
The beam is delivered through a fiber optic cable to the welding head.
Beam Focusing:
The laser beam is focused onto the workpiece using a collimating lens and focusing lens, creating a small, high-energy spot for precise welding.
Wire Feeding Mechanism:
A wire feeder supplies filler material (e.g., aluminum, stainless steel, or other alloys) into the weld pool.
The wire is fed at a controlled speed (adjustable based on welding parameters).
The feeder can be synchronized with the laser pulse or continuous wave (CW) mode.
Melting & Joining:
The laser beam melts both the base metal and the filler wire, forming a strong metallurgical bond.
The wire compensates for gaps, improves weld strength, and reduces cracking.
Shielding Gas (Optional):
An inert gas (Argon, Nitrogen, or Helium) may be used to protect the weld pool from oxidation.
