Inrotech-MicroTwin

Inrotech Microtwin®

Robotic Welding solution for shipbuilding

The Inrotech-MicroTwin® is a compact and light weight gantry with 2 welding robots, welding machines and a scanning system for identifying stiffeners on panels. Specifically designed for the welding of micro panels, sub-assemblies and T-profiles 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 operator has the option of selecting chain weld, change welding sequence etc. This is easily done on the intuitive touch panel. The robot is delivered as a “plug-and-play” unit and is fully operational once the rails, safety curtain, or fencing, has been installed and the system has been connected to power, shielding gas and compressed air.

Minimal down-time, maximal productivity

Not only automatic welding — also adaptive intelligence

Place the items to be welded randomly within the workspace of the Inrotech-MicroTwin® and press the start button on the intuitive touch panel. The scanning of the panels now takes place. It only takes a few minutes with a scanning speed of 36 sqm per minute.

The operation of the Inrotech-Microtwin® is very simple

Once the scan is completed, the exact position of each profile is verified by the laser sensor, which is integrated in a housing also holding the welding gun. The welding of the profiles now takes place without any further input from the operators side. This means: Place the panels and push the start button…that’s it!

Twin robot gantry

Compact twin-robot gantry for micro panels

2 FANUC robots on a lightweight aluminium gantry
Gantry width up to 6 m
Rail system up to 60 m, configurable in separate working zones
Lincoln Electric R450 power sources with 4R200 AutoDrive wire feeders
Designed for micro/mini panels, sub-assemblies, T-beams and small parts

Inrotech-SensLogi®

From Real Geometry to an Automatic Welding Sequence

Overhead scanning at 6 m/min
Up to 36 m²/min at a 6 m gantry width
Line scanners create a 3D topography of the panels
Local laser sensing identifies profile type, dimensions and precise start and end positions
After scanning, the operator can adjust weld type and size before automatic welding begins

2 ROBOTS, ONE SYSTEM

Let the System Plan the Welds

Inrotech-SensLogic® combines measured geometry with welding logic. No CAD file transfer.
No manual macro selection. A production workflow built around the operator

DOCUMENTED WELDING PERFORMANCE

Parallel welding. Clearly specified performance

PB position: up to 55 cm/min per robot
Combined PB welding rate: up to 110 cm/min when both robots weld simultaneously
PF position: up to 22 cm/min per robot
Combined PF welding rate: up to 44 cm/min with both robots welding

FLEXIBLE PRODUCTION LAYOUT

One working zone welds. Another prepares.

Separate safety zones can allow loading and panel preparation outside the active welding zone
Rail length and gantry width determine the effective welding area
A 16 m rail example provides a 13.35 m effective welding length
Also applicable to suitable skid structures and other assemblies, subject to application review
