A fiber laser welding machine uses a high-intensity fiber laser beam to join metal parts with extreme precision and minimal heat distortion. Unlike conventional arc or MIG welding, this advanced technology channels laser energy through an optical fiber, creating a small, concentrated heat source. The result? Faster welds, deeper penetration, and immaculate seams even on thin or reflective materials.
Core Components Include:
Fiber laser source: Generates the laser beam.
Optical delivery system: Transmits the beam via fiber optics.
Welding head: Focuses and directs the laser onto the material.
CNC or handheld controller: Allows precise manipulation for complex joints.
