TOKYO--(BUSINESS WIRE)--May 16, 2018--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.

*Compared with conventional technology during welding using SPHC (hot rolled material)

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.
