WeldLogic Technology - Adaptive Multipass Welding Technology
The Inrotech-Crawler is a highly advanced state-of-the-art piece of robotic welding technology, which has the potential of revolutionizing the welding business.

Although it includes advanced technology, it is extremely easy to use: Install the titanium rails in a proximate distance to the welding groove. Define start and stop points and press “start”. The robot now automatically identifies the welding groove by means of a 3D scanner and automatically calculates the number of passes, location of each pass, welding speed and weaving pattern; no matter position or plate thickness.

The weight of the robot carriage is 45 kg.


Inrotech uses a very small customized robot which is placed on a carriage running on a flexible rail system, which is fixed to the substrate by means of switchable magnets. These ensures a safe dependable fixation to the substrate (as long it is magnetic).


The rails are made of titanium, which is both flexible and strong. They come in standard lengths of 3m but can be adjusted to any desired length.

The carriage (which has a weight of 45 kg only!) holds a multitude of functions: 3-D gyro for automatic adjustment to welding position, drive, water cooler, gas cup cleaner, toggle buttons, tool exchanger for welding gun / scanner, emergency button, wire straightener, camera, temperature sensor etc.

The carriage is connected to the controller/welding machine by means of a Super snake system, which makes the cable extremely light and flexible.

Furthermore, the system is provided with battery back-up for safe shut downs in the event of power cuts.

We dare to say that this is the most advanced and versatile welding machine on the market.


The Inrotech-Crawler has the ability to target a huge number of welding jobs in the global industries. Any kind of butt-weld connection, no matter shape or position, is a potential welding target for the Inrotech-Crawler. Obvious targets are; inside and outside of large pipes connections of any type and with any thickness of steel, block assemblies both inside or outside, many kinds of plate and seam weldings etc. Suitable for industries like: Oil & Gas, Offshore, Shipbuilding, Construction, Renewables, Wind & Hydro and many more.


The Inrotech-Crawler can be positioned on flat or curved surfaces (down to 2 m. diameter). In vertical or horizontal position (even over-head positions).

The rails can be joined to any desired length.

The operator must position the rail within a proximate distance from the weld groove, so it is within reach of the robot. When the rail is in position it is fixed by simple switchable magnets and can easily be disconnected again.

Finally, the operator just has to give very few commands or even just press START to initiate the fully automatic scanning and welding process of the Inrotech-Crawler.
