Your welding process drives the robot configuration, torch selection and parameter set. CBOXTEC systems support the processes most common in structural and heavy fabrication:
Primary arc welding process for structural steel. Wire-feed automation, high deposition rates, 60–300 cm/min travel speed on typical fillet welds.

Thin-wall and critical joints. Low spatter, precise heat input. Used on stainless, aluminum and alloy pipe work.
Request a Quote
Resistance spot welding for sheet metal and automotive body assemblies. Fast cycle times, no filler material.
Request a Quote
Thick stainless and alloy plate. Deeper penetration than TIG at higher speeds. Keyhole mode for single-pass welds on 6–12 mm plate.

Narrowest heat-affected zone. Precision thin-gauge joints and high-speed seam welding where distortion must stay under 0.3 mm.

A plant that fabricated 8,000 tonnes of H-beam columns annually was suffering higher than targeted attrition of welders, making it difficult to replace them. Two manual welding stations running 1 welder each were the bottleneck.
2 CBOXTEC rail-mounted welding robots fitted with Bochu teachless programmation and long-range seam tracking. Total rails length: 14 meters at each station.
Pendant programming has been fully eliminated by the teachless system. Now the operator imports the Tekla model at the start of each batch, loads the pieces onto the fixturing and supervises both robots from one console.
A mid-size shipyard needed to automate bulkhead and deck panel welding but could not install permanent robot cells inside the hull. Space between stiffeners measured 400–600 mm, and the panels moved between stations.
4 CBOXTEC collaborative welding robots with magnetic bases and arc tracking.
Cobots roll between stations on deck, clamp magnetically, and the operator drag-teaches the first pass. Arc tracking handles the ±2–3 mm fit-up gaps that are normal on tack-welded ship panels. One operator now supervises two cobots.
Previously 4 welders in pairs would weld 3.2 m wide, 1.0 m deep box girder sections with diaphragm plates at 400 mm centers. Quality inspection found 6% of the batch outside flatness tolerance.
1 CBOXTEC gantry type welding robot with vision 3D line-scan and point cloud reconstruction. Portal span: 4.5 m.
Before welding, the 3D vision system scanned each girder section, built a point cloud model of the actual part geometry and generated the weld path from the scan rather than from drawings. Flatness rejects dropped to 0.8%.
CBOXTEC robotic welding systems are deployed across the heavy-fabrication sectors that shape modern infrastructure and transport.
High-volume repetitive arc welding onto fillet joints material 6-40 mm thick. Rail-mounted and cantilever systems handle the longest seams.

Gantry robots span wide plate work; cobots handle confined compartment welding where full-size cells cannot fit.
Explore Solution
Gantry systems to fit 5 m spans are used for handling the over-sized plate assemblies. Point cloud reconstruction welds join components without a clean 3D model.
Explore Solution
Tight dimensional tolerances require uniform welds and low distortion. Workstation cells with automated loading maintain cycle time uniformity across 3-shift production.
Explore Solution
Spot welding robots for body-in-white lines; MIG/MAG arc welding cells for structural fabrication. High-volume, low-mix production with cycle time aim of 60 seconds or less.
