Fully automated welding of crane booms
Challenge
- Production of intermediate sections for crane booms, varying from 3,000 to 12,500 millimeters in length, with a width of 900 to 3,000 millimeters
- Intermediate sections previously joined and welded manually in positions detrimental to health
Solution
- Use of two completely identical robotic welding cells
- Handling and provision tasks in the cell with two 6-axis robots: ES165 and ES200RN
- Tack-welding and subsequent finish-welding of the diagonal tubes with two EA1900 welding robots
- The ES200RN is mounted on a traversing axis that runs the length of the system, serving as the interface between the welding station and the workpiece provision area
Results
- Innovative, fully-automatic special welding system
- Perfect precision in the welding system to within a tenth of a millimeter
- Increased productivity
