Fiber Laser Welding Head


Our unique arc and laser hybrid welding technology realizes an unprecedented level of welding quality.


Our proprietary arc and laser hybrid welding head provides the benefits of the two welding processes, "arc welding" that allows for padding and "laser welding" that features high speed with less strain.
Our fiber laser welding heads allow for welding in arbitrary directions that has been difficult with conventional welding technologies, realizing high-speed and stable padding with a sufficient penetration of weld metal.

Benefits of Arc Welding and Laser Welding Integrated into a Single System

Cutting capacity comparison
  • Our unique coaxial arc and laser technology enable the benefits of both arc and laser welding processes to be incorporated into a single system for the improvement of machining efficiency.
  • This technology can ease the required accuracy for the welding groove because the arc melts the laser-irradiated portion to provide a sufficient weld bead even if there is a slight gap.
  • The technology enables welding with a deeper penetration of weld metal than laser-only welding because the arc is concentrated in the key hole formed by the laser to produce a large heat input.

Coaxial Arc and Laser Technology for Welding in Arbitrary Directions

General welding systems that perform horizontal arc welding only allow for padding in a fixed direction.
On the other hand, our welding heads are designed to supply the arc from the central axis in the same way as the laser beam, allowing for padding in a free 3-dimensional trajectory independent of the direction in which the arc is supplied.

Use of a Fiber Laser as the Light Source for All Operations

The system uses a fiber laser to solve the problems inherent to conventional welding technologies such as the quality, speed, and cost of welding.

  • Smooth and fine weld bead due to continuous radiation with a continuous-wave laser
  • Strong resistance to leakage due to a low probability of blowhole generation even in butt welding
  • Less welding strain due to a small spot diameter and light-collecting density of the laser
  • Process monitoring, seamless tracking, and other options to enable accurate welding depending on the welding conditions
