High power fiber laser FO series ring mode
Adjustable Ring Mode (patented)
The beam irradiated from ARM is separated coaxially to Center and Ring and reaches the processed area. Each beam of Center and Ring is generated inside the oscillator without using external optical system and is transmitted to the exit port while maintaining beam quality.
Center + Ring
This completely new beam mode realizes advanced processing in welding, cutting and surface treatment, which never been a possible by conventional laser. Reducing a sputter during welding galvanized steel, drastic improvement of welding quality of aluminum materials, and other new processing technology are expected to be developed. A various combination of independently controllable laser in one beam brings you significant arm to your laser processing.
Processing application example
ARM solves problems such as sputtering and defects which occurs during welding processing on aluminum and galvanized steel.
Welding : Aluminum
Welding process on aluminum materials by laser used to bring defects such as porosity(void) and undercut(thinning). In addition, vast amount of sputters generated during the process damages product itself and processing equipment. With ARM, we can solve these problems.

Galvanized steel sheet lap welding (no gap)
In lap welding of coating materials such as galvanized steel plate and galvalume steel plate, techniques are adopted in which materials are overlapped with gaps to avoid the occurrence of sputters and porosity (void). Adjustment of the beam profile by ARM enables high quality welding without any gap, then processes such as clearance management and post-treatment may be reduced.

Benefits of Center-Ring coaxial irradiation and independent control
- Optimizing processing conditions each for variety kind of materials
- Thanks to ring shape beam, there is no limitation on processing directionality
- Lap welding of galvanized steel (no gap)
- Reducing a sputter during welding processing
- Piercing and end point optimization
