Comau and Fincantieri, are presenting the first result of their joint collaboration at Automatica 2023 in Munich, Germany: MR4Weld (Mobile Robot for Welding) mobile robot, an innovative outdoor automation solution to improve quality, performance and well-being during labor-intensive welding activities. The companies have also renewed their strategic agreement to apply technology, digitalization and innovation within cutting-edge mobile robotic solutions that will increase production speed and worker well-being by automating traditionally manual processes.

Having first signed a letter of intent in 2021, which was aimed at developing robotized steel welding solution prototypes and the resulting construction of a series of machines – after successful completion of production tests of the prototypes which are currently undergoing, Comau CEO, Pietro Gorlier, and Fincantieri CEO, Pierroberto Folgiero, have signed a renewed agreement, which foresees the development of additional mobile robotized machines and solutions for unstructured environments.Source: ComauSource: Comau

Considered a new paradigm in bringing automation beyond the factory floor, the MR4Weld mobile robot is being tested and will be subsequently used within Fincantieri shipyards to autonomously weld steel structures, with a possible three-fold increase compared to a manual process. It features a high-payload, six-axis articulated robot fitted with a welding torch that is installed on a tracked undercarriage and equipped with an integrated vision system to autonomously identify welding joints. More importantly, it guarantees better welding quality while reducing ergonomic risks, helping the transformation of the shipbuilding production process by ensuring greater flexibility and improved safety in addition to lower overall costs.

Designed to be able to move in any environment and to collaborate with workers, MR4Weld can be easily managed by a single operator during transfer and welding activities. The system also employs digital tools to collect welding and production data that can be used to record the welded joints. Since MR4Weld is in complete compliance with current safety regulations, it can be used without fences on each of the multiple vessel decks. The cutting-edge solution can also be seamlessly integrated within Comau’s digital infrastructure, further safeguarding the robotic system’s productivity and profitability.

As part of the renewed collaboration, the companies will develop advanced and mobile robotics to automate other repetitive activities of the shipbuilding processes including those characterized by vertical and non-linear surfaces as well as unstructured environments, in addition to the testing of Comau’s exoskeletons for further improving the operators’ ergonomic conditions and well-being. Fincantieri will also work with Comau to strengthen and upgrade the technical skills of its operators in terms of using and programming the robotized mobile systems, by adapting to the shipbuilding operators dedicated advanced training formats, which are already developed by Comau. Implementing automated solutions for highly repetitive and non-high value-added production activities represents one of the pillars of Fincantieri’s strategy.

Comau will also take yet another step toward differentiating its core business and expanding into new segments beyond the factory floor. The companies will also begin industrializing their unique MR4Weld robotics solution, which can be applied not only to the shipbuilding industry but also to industries that require the production of large steel infrastructures, among others.
