What is Fiber Laser Welding & How Does It Work?

What is Fiber Laser Welding?

Fiber Laser Welding is an advanced, non-contact thermal processing technology. It generates a high-intensity, ultra-concentrated laser beam using rare-earth-doped optical fibers (such as ytterbium) as the gain medium. Delivered directly to the workpiece via flexible fiber-optic cables, the concentrated photon beam instantly melts metal joint edges to create a strong, clean, and deep-penetration weld seam upon rapid cooling.

Utilizing a continuous optical beam with a focused spot size of 0.2mm – 0.5mm, our fiber welder delivers deep melt penetration and ultra-clean, uniform weld seams. Engineered for continuous duty and automated manufacturing, it achieves exceptional joint strength with high processing speeds and minimal post-grinding requirements.

Working Principle: The 4-Step Fusion Process

01

Fiber-Guided Beam Generation

Active diode lasers pump energy into the optical fiber core, generating a stable, high-luminance laser beam (1064 nm wavelength) with superior optical beam quality and electro-optical efficiency (>30%).

02

Precision Optical Focusing

The high-energy beam travels through a sealed fiber-optic cable into the torch head, where collimating and focusing lenses concentrate the laser down to a microscopic focal spot (as fine as 0.05 mm).

03

Instant Thermal Melting & Keyhole Formation

Upon contacting the metal surface, the laser energy is absorbed instantly. It operates via Conduction Mode for ultra-fine micro-spotting, or Keyhole Mode for deep penetration into metal sheets up to 8.0 mm.

04

Shielded Cooling & Flawless Seam Solidification

Inert shielding gas (Argon or Nitrogen) flows around the molten pool to prevent oxidation. As the torch moves, the molten metal rapidly cools, forming a bright, smooth weld seam with zero thermal distortion.
