Fully automated welding of large ship blocks. These massive, one-off structures come with tight spaces and complex geometries. Suspended between double hulls, intelligent robots coordinate seamlessly — welding efficiently, without collisions.

All you need to know

The Block Welding Gantry is engineered for the heavy-duty demands of modern shipbuilding. It offers precise, automated welding of large steel assemblies, using CAD-driven robot paths and advanced collision avoidance. Whether dealing with thick plates, various weld joints, or complex block configurations — the system delivers consistent, high-quality welds with minimal manual intervention.

Fully automated welding of large block sections

Welding massive double-hull blocks requires more than just reach — it demands control, consistency, and coordination. The Block Welding Gantry delivers fully automated welding inside these giant structures, handling one-off geometries without compromising speed or quality.

Multi-robot coordination in confined spaces

Inside large double-hull blocks, space is limited — but precision can’t be compromised. The Block Welding Gantry suspends multiple robots within the structure, each following automatically calculated paths to prevent collisions.

One operator, full control

Despite the complexity of the task, a single operator can oversee the entire gantry. Through a graphical interface, they can load jobs, monitor progress, and intervene when needed. This reduces labor cost and increases uptime.

No programming needed during day to day operation

Every Block Welding Gantry is powered by RinasWeld, KRANENDONK’s intelligent software for automated welding. RinasWeld reads your 3D CAD model, detects all seam locations between double-hull blocks, and calculates accurate robot paths — even in confined areas. It generates a complete collision-free welding program and sends it to the gantry. Operators simply select the job on the touchscreen and start production, ensuring consistent welds and safe operation in even the most challenging environments.
