Welding quality is a key requirement in shipbuilding, especially when working with materials like aluminum.
That’s why we hold the UNI EN ISO 3834-2 certification—the most rigorous international standard for fusion welding of metals.

This certification ensures that all our work—from lightweight structures to complex superstructures—is carried out with the highest standards of quality, traceability, and safety.

Thanks to the 3834-2, we are fully qualified for the construction and refitting of aluminum vessels—a field where precision, process control, and expertise truly make the difference.

At Cartubi, competence isn’t just a value—it’s a certified guarantee.
