Plus de 100 ans d'engagement en faveur du progrès technique ont fait de Yaskawa le fabricant leader dans les domaines des variateurs, de la technologie d'entraînement et de la robotique.
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
