Gas-shielded robotic welding of H-section columns, roof beams and crane beams on a 12 m ground rail.
Starting prices reflect base equipment configurations. Final pricing depends on system configuration, application requirements, shipping destination, installation, commissioning, training and project scope.

A seven-axis upright workstation combining a six-axis welding robot with a 12 m robot ground rail, so the robot travels along the length of the workpiece instead of the workpiece being repositioned.
It is designed for relatively open structural steel members where fillet welds run flat, along planar polylines, or vertically.
Flat fillet welds
Planar polyline fillet welds
Vertical fillet welds
