Long fabricated beams — roof beams, crane beams and rail beams — welded along rail-mounted travel axes.
Roof beams, crane beams and rail beams share one production problem: the component is long, heavy and awkward to reposition. The motion system, not the robot arm, defines what is possible.
Rail-mounted and inverted configurations move the robot along the workpiece, keeping the component stationary throughout the weld sequence.
Members longer than a fixed robot working envelope
Heavy workpieces that are difficult to reposition
Long uninterrupted weld seams
Access to seams on both sides of the member
Recommended for consideration. Final system selection depends on your component dimensions, welding process and production requirements.
Gas-shielded robotic welding of H-section columns, roof beams and crane beams on a 12 m ground rail.
Inverted-mounted welding robot on a 12 m rail for improved torch access to open structural members.
Linear travel axis that extends the working range of a welding robot.
Long straight fillet welds on repetitive beam and column geometry — the highest-volume welding work in structural steel.
Root, filling and capping passes on thick-section box columns, including full-penetration welding.
Large bridge panels and units with long weld seams and complex geometry, handled by 8-axis and 9-axis systems.
