Abstract

System for 2D and 3D metal processing with fiber optic laser and plasma, that includes CNC for cutting metal plates with fiber optic laser and plasma and a robot arm for cutting and welding metals with fiber optic laser. The system is characterized because it includes three processes in one single equipment: metal cutting with fiber optic laser, metal cutting with plasma and metal welding with fiber optic laser. The equipment has a computer numerical control (CNC) system and a working area of 1200×3000 mm for cutting metals; it has two cutting heads, one for fiber optic laser and one for plasma as well as one 360° rotating robot arm on which the laser welding head or the laser cutting head can be placed for 3D welding, or cutting circular or rectangular pipes, respectively.

Claims
