For heavy‑duty equipment manufacturers, welding of large box‑type components, wind‑power structural parts and large‑bore valves creates persistent production challenges. Huge workpiece dimensions and lengthy seams lead to long cycle time with single‑robot welding, accompanied by severe thermal distortion. Manual welding meanwhile suffers from labour shortages and inconsistent finished quality. The dual‑robot gantry welding workstation delivers an efficient automated welding path for these complex oversized parts. Mounted on a travelling heavy‑duty gantry frame, two welding robots move across long‑travel ground rails. Dual‑robot coordination meets mass‑processing requirements for heavy‑industry large components.
The workstation includes heavy‑duty gantry frame, long‑stroke ground rails, dual robot units, synchronous control system, laser seam‑tracking device, welding power sources, safety enclosures and HMI cabinet. Twin robots can work synchronously for symmetric seams or operate independently for different welding zones. Built‑in anti‑collision programs avoid motion interference and ensure long‑term stable operation. Supporting MIG/MAG, TIG and plasma cladding, it executes structural welding for steel beams and offshore parts, as well as wear‑resistant alloy cladding for sealing surfaces of large‑size valves.
Synchronized dual‑robot welding creates even heat input and lowers distortion risk for large weldments, reducing post‑weld correction and rework and greatly boosting productivity versus single‑robot gantry solutions. Laser seam‑tracking corrects positioning deviation caused by workpiece clamping in real‑time. Storable reusable process parameters guarantee uniform weld quality in mass production and cut welding defect rates. One operator is sufficient to supervise the whole station, easing the shortage of skilled welders. Enclosed safety barriers isolate arc flash and welding fume to raise workshop safety standards.
Gantry span and rail travel length can be customised according to workpiece dimensions for diverse production sites. Full turn‑key service covers on‑site installation, commissioning and practical training, helping heavy‑industry manufacturers break large‑part welding bottlenecks and realise simultaneous improvement in productivity and product quality.
