SPECIAL REPAIR WELDING AND WELDING
Repair welding is a complex technological discipline that requires certain specific knowledge and skills. In addition to knowing the function of the parts being repaired, adequate metallurgical knowledge of the materials to be used is required.
​
Welding procedures:
- REL, TIG, MIG-MAG, AUTOGENIC WELDING, EPP, METALIZATION
UNDERWATHER WELDING
Underwater works performed by divers to maintain ships, submarines, platforms, pipelines, etc. are very complex activities. Organizing such jobs requires a large number of highly skilled people and mobilizing a huge amount of equipment. An irreplaceable role in the maintenance of underwater structures is played by the wet underwater welding process, which can very quickly and effectively repair the fractures of structural elements on the spot, and in the case of good preparation and organization, installation welding is possible.
WELDING TECHNOLOGIES AND EXPERT SUPERVISION
Welding is a complex process. The conclusion is that without advanced welding technology, modern projects in shipbuilding, industry and offshore would be impossible.
Adriatic 21 offers the following:
- Development of welding plans
- Development of welding control plans
- Design of technological procedures
- Periodic testing of facilities in operation
- Supervision of the construction and installation of welded structures
- Certification of welding procedures
- Design of project documentation and testing of pressure vessels
The key to welding technology is in the details.
We carry out professional supervision in the ship, industrial and off shore program. A team of specialized and professional engineers, continuous education, extensive years of experience are just some of the qualities that characterize us.
NDT CONTROL OF WELDS
There are various types of NDT testing procedures to ensure the high quality of our welds:
- Visual examinations
- Penetrant testing
- Magnetic testing
- Ultrasound testing
- X-ray examination
and other special procedures depending on the application where welding is used.
