The Laser Processing Test Field has an experimental system and a computer calculation system to develop laser cutting/welding technology for decommissioning. The experimental system consists of a laser oscillator and three multi-jointed arms equipped with devices such as a laser head. The computer code predicts melting and solidification phenomena in materials based on laser heat input and heat transfer models.
Three multi-jointed arms equipped with a laser head, a test specimen holder and a spatter collector are installed in the laboratory. A 10kW CW laser oscillator is placed in a different area and connected to the laser head by an optical fiber. Various kinds of laser cutting/welding processes are examined and planned using this test system.
Multi-Jointed Arms Laser Processing System
●Laser power unit: 10kW fiber laser (CW)
●Multi-jointed arms:
(1) Laser head arm
(2) Test specimen holder arm (Maximum weight 15kg)
(3) Spatter collector arm
Experiments of cutting, welding, perforation and surface heat treatment are implemented by the operation of the three arms under different laser processing conditions. The cutting test of a triangular-prism shaped specimen is shown in the photos below as an example.
