SensLogic Technology 

The Inrotech-MicroTwin is a compact and light weight gantry featuring 2 small robots, welding machines and a scanning system for identifying stiffeners on panels. Specifically designed for the welding of micro panels in the shipbuilding industry, but can also be used for other purposes.

Works fully automatic, push the “start” button; after completed scanning the welding starts automatically.


The Inrotech-MicroTwin is named as such due to the fact that  two welding robots are working together – as a pair of twins. An aluminum mini-gantry forms the basis of this welding robot system. In one of the side towers the two robot controllers are placed together with the electrical cabinet. The other side tower holds the two Kemppi A7 welding machines.

MicroTwin can be delivered with a gantry at any width (internal) up to max. 6 m.

On the top of the gantry, Inrotech’s SensLogic line scanners are positioned. These scanners create an overall image of the panels, which are located in the working area.

The welding gun housing holds a laser sensor for accurate sensing of where welding starts, ends and connections.


The gantry system is running on a tooth-rack rail system, which can be installed directly onto the floor or on conveyor systems.


The Inrotech-MicroTwin is specifically designed for the welding of micro panels, mini panels and sub-assemblies in the shipbuilding industry. However, it can be used for a variety of welding jobs across various industries.

Being a fairly new product, the Inrotech-MicroTwin with its SensLogic technology, still needs to be explored on the global stage before its full potential is clear. However, no doubt the intelligent and self-programming functionalities are extremely appealing for many customers world-wide.


Operation is as simple as can be: push the green button and wait until the panels are welded! No further input is required from the operator.

As in all Inrotech solutions the user interface is an intuitive touch panel, windows and icon based. All icons on the touch screen are self-explanatory and can be translated into any language. Even the cameras on the gantry are displayed on the large touch screen.


The Touch screen can be placed either on the floor next to the line or on the gantry in a strong and flexible arm.

Through the touch screen the operator has access to several functions and features enabling the operator remotely to control any given situation of the Inrotech-MicroTwin welding robot, performing service, pause for wire change or whatever is necessary.
