The cantilever robot welding workstation has shown irreplaceable value in the manufacture of millimeter-level thick plate steel structure with its unique spatial layout and high load capacity. Its inverted design releases ground space, and its large-span operation range perfectly adapts to the welding needs of medium and large components, becoming the core production equipment in the heavy industry field.
Longitudinal seam welding of bridge steel box beam
The workstation cantilever spans the top of the steel box beam, and the robot moves along the track to complete the ultra-long top plate butt weld. Compared with traditional manual segmented welding, it can eliminate the problem of joint misalignment and improve the overall structural strength of the box, which is especially suitable for ultra-large span projects such as cross-sea bridges.
Assembly welding of H-beams in buildings
For the flange plate and web fillet welds of heavy-duty factory steel beams, the workstation cooperates with the automatic flip table to achieve four-way welding. The robot's inverted operation avoids interference with ground equipment, completes all welds in a single clamping, and significantly reduces the number of hoisting times.
Circumferential seam of crane boom
The cantilever rail is arranged along the length of the boom, and the robot completes the internal and external circumferential seam welding of the box-type structure. Its high-rigidity structure can support high-current submerged arc welding process, ensure the penetration of thick plate multi-layer welding, and replace traditional gantry equipment.
From 100-ton bridge towers to giant pressure vessels, the cantilever robot welding workstation is reshaping the process standards of heavy industry welding with the advantages of "space efficiency + thick plate control". In the future, with the upgrade of flexibility, this technology may replace traditional manual and fixed equipment in more medium and thick plate fields, and become a landmark solution for intelligent steel structure manufacturing.
