Inrotech-Crawler
Inrotech-Crawler®
Heavy fabrication multipass welding
The Inrotech-Crawler® travels on flexible titanium rails, magnetically attaching to large steel structures—flat, curved, vertical, overhead—ideal for welding pipes, tanks, vessels, ship hulls, bridges and more. The Inrotech‑Crawler™ brings adaptive, automated, high‑quality multipass welding directly to large structures—enhancing productivity, precision, and flexibility—without requiring specialized programming or setups.
Define start and stop points and press “start”. The robot now automatically identifies the welding groove by means of a line scanner and automatically calculates the number of passes, location of each pass, welding speed and weaving pattern; no matter position or plate thickness.
Get to know our Inrotech-Crawler®
The Inrotech-Crawler® features proprietary WeldLogic software, which automatically scans grooves, calculates the number and placement of weld passes, and adjusts welding parameters in real time. This intelligent automation helps ensure consistent, high-quality multipass welds with minimal operator input.

Multipass welding - large tubes
Flexible robot in almost any position
The Inrotech-Crawler can be positioned on flat or curved surfaces (down to 1 m. radius). In vertical or horizontal position (even over-head positions). This gives high flexibility when handling different joint orientations and part geometries, helping maintain consistent weld quality without extensive repositioning of the workpiece

Welding targets
Adaptive multipass welding
The Inrotech-Crawler has the ability to target a large number of welding jobs in the global industries. Butt-weld connection and other connection types requiring multipass welding, almost no matter shape or position, is a potential welding target for the Inrotech-Crawler. Obvious targets are; large pipes connections (in- and outside), assembly of blocks in shipbuilding, Storage tanks, Construction, renewables and many more. Can be employed in workshops or at construction sites
