Naval carpentry is a key sector in the maritime industry, essential for the construction, maintenance, and repair of a vessel’s metal structures. The proper functioning of a ship depends on the quality of the materials used, the precision of the structural work, and the expertise of the professionals involved.

With over 70 years of experience, Se.r.navi stands out for the quality and reliability of its services. The company offers a wide range of carpentry work, from certified welding to the construction and repair of naval structures, as well as on-board electrical and electronic systems. Thanks to a highly specialized team and cutting-edge equipment, Se.r.navi delivers tailor-made solutions for every need.

Welding is one of the most critical aspects of naval carpentry—a key technique for assembling and repairing metal structures. The quality of the welding directly impacts the strength and safety of the vessel, which is why Se.r.navi employs a team of qualified welders certified by international bodies such as RINA and DNV-GL.

Se.r.navi’s professionals are available seven days a week, offering a wide range of welding techniques to meet the diverse needs of the maritime sector.

• Electrode Welding: A traditional method that ensures strong, long-lasting joints, ideal for carbon steel and stainless steel.

• MIG (Metal Inert Gas) Welding: Mainly used for aluminum and light alloys, offering high precision and speed.

• MAG (Metal Active Gas) Welding: Suitable for carbon steels, providing deep penetration and excellent mechanical resistance.

• TIG (Tungsten Inert Gas) Welding: Perfect for high-precision work, used on thin materials and special alloys requiring flawless finishes.

• Submerged Arc Welding: Ideal for thick materials, offering high productivity and quality through full protection of the weld pool.

• PTA (Plasma Transferred Arc) Welding: Used for overlaying special materials such as bronze and stellite, ensuring excellent wear and corrosion resistance.

Naval structures are exposed to intense mechanical and environmental stress, requiring regular maintenance to ensure vessel safety and longevity. Se.r.navi provides highly specialized repair services for all structural parts of a ship.

• Ship Hulls: Repairs of damaged plates, replacement of compromised sections, and structural reinforcements to improve vessel strength.
