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
