Flexible beam forming technique using an optical head equipped with ac米兰中文官方网站 function
(Note) The optical head with ac米兰中文官方网站 function was jointly developed with Furukawa Denshi Co., Ltd.
The key feature of our ac米兰中文官方网站 is flexible mode design. The beam mode can be changed to the desired shape to obtain the optimum pattern and intensity distribution for each workpiece.
Beam forming principle and ac米兰中文官方网站 design
-
Principle of light diffraction
Diffraction occurs when plane waves pass through the slits. This causes wave crests to intensify as they overlap, and the white area becomes diverged light.
-
DOE image
Diffractive optical elements (DOEs) use this principle to split the laser beam.
Design specifications
- The light profile is simulated from the design parameters (wavelength, optical system magnification, desired ac米兰中文官方网站 shape).
- By forming a multilevel structure with information on different grating periods, it is possible to obtain a multi-branch ac米兰中文官方网站 pattern of controlled branched light intensity.
- The DOE obtained with ac米兰中文官方网站 proprietary technology is characterized by high efficiency and high positional accuracy.
Spatter reduction with ac米兰中文官方网站
Spattering can be dramatically reduced by applying ac米兰中文官方网站.
The processing quality improvement effect obtained with ac米兰中文官方网站 can be verified at our Chiba Works' Application Lab, or at our external partner laboratory in the Chubu District.
ac米兰中文官方网站 offers dramatic benefits for the welding of various materials (highly reflective materials such as zinc-plated steel plate, high-strength steel sheet, aluminum alloy, iron, stainless steel, copper, aluminum) that require the suppression of spattering and blowholes.

The mechanism for eliminating spatters and blowholes using ac米兰中文官方网站
Spatter and blowholes can be reduced by heat input design that matches the customer's material, process, and cycle time.
-
Conventional technology
Issues in high-speed (high power) processing
- Local heat input distribution in ac米兰中文官方网站hole
Fluidity turbulence due to induced vapor
Spatters and blowholes generated
Spatter : Scattering of molten metal
Blowhole : A bubble hole that remains in welded metal - Local heat input distribution in ac米兰中文官方网站hole
-
ac米兰中文官方网站
High-speed processing with DOE, matches customer's material, process and cycle-time.
- Preheating effect around keyhole
Vapor pressure is dispersed to the surrounding area and fluidity is rectified
Achieves high quality weld by achieving spatterless and blowholeless
- Preheating effect around keyhole
