Mitsubishi Electric's New Fiber-laser Welding Technology Dramatically Reduces Spatter for Faster Welding

Raises the welding quality and productivity of high-power fiber-laser welding for industrial applications

TOKYO--()--Mitsubishi Electric Corporation (TOKYO:6503) and its affiliate company Tada Electric Co. announced today their joint development of a new fiber-laser welding technology that cuts flying molten metal (spatter) by 95 percent or more*. Whereas conventional spatter levels can lower the quality and speed of fiber-laser welding, the new low-spatter technology raises the welding quality and productivity of high-power fiber-laser welding for industrial applications such as steel processing, automobile production and electrical equipment installations. The new technology is expected to be incorporated in laser-welding machines that will appear in 2019.

Key Features

1) Combined high/low-power laser beam reduces spatter by 95 percent or more for improved welding quality

  • Suppresses spatter regardless of welding speed by irradiating a low-power laser beam around the high-power laser beam.
  • New optical system simultaneously generates high-power and low-power laser beams from the output beam of feeding fiber.
  • 10-kW high-power fiber laser cuts spatter by 95 percent or more for improved weld quality.

2) Doubles the speed of welding by suppressing spatter, contributes to increase in productivity

  • Welding speed does not need to be lowered to suppress spatter, so the system’s 10-kW high-power fiber laser can weld at twice the speed of a conventional system when welding material of the same thickness.
