Underwater welding represents one of the most complex technical challenges in marine engineering. Combining knowledge of metallurgy, hyperbaric physics, and specialized diving techniques, this discipline allows for critical repairs to be carried out on submerged infrastructure without the need to dismantle or relocate it.
Work Methodologies
- Wet Welding:
- Use of special electrodes coated with insulating material
- Protection by means of a bubble of gases generated by the electrode
- Arc temperatures exceeding 3,000°C in an aquatic environment
- Dry Chamber (Hyperbaric) Welding:
- Installation of watertight enclosures around the work area
- Precise control of pressure, temperature and humidity
- Welding quality comparable to that performed on the surface
Specific Applications
- Repair of oil platforms
- Maintenance of underwater pipelines
- Reconstruction of port structures
- Repair of boat propellers and rudders
Technology and Security
- Triple-insulated welding equipment
- Permanent diver-surface communication systems
- Continuous monitoring of physiological parameters of the welder diver
- AWS D3.6 International Certifications
