Robotic Welding Complex for Shipbuilding Structures
Purpose of the Robotic Welding System
Fully automated welding process of flat ship structure units: micro-panels, floors, brackets, etc., made from sheet, angles, T-sections, bulb flats. Capable of producing welded joints on parts with dimensions up to 3200×23,000 mm (working area 3200×90,000 mm).
Material of workpieces: shipbuilding steels, structural steels.
Welding position: flat, horizontal, vertical
Type of welding: MIG/MAG welding with solid wire in Ar+CO2 shielding gas, flux-cored wire in CO2.
Functions performed by the system:
- automated detection of workpieces (assemblies) placed on the worktable using a specialized scanning system;
- identification of workpiece type and its geometric position;
- generation or application of pre-prepared welding trajectories to 3D models, and computation for safe robot movement between welding operations;
- seam tracking and correction using data measurement during torch oscillation throughout the welding process;
- multi-pass weld capability with different bevel configurations;
- welding with solid wire and flux-cored wire.
