An Assessment over Underwater Welding Technique

Abstract

The underwater welding is developing technology of the present and the future. Many ships and offshore platforms need the underwater welding process during emergency. There are many research institutes in the world developing techniques for underwater welding. Welding in marine and offshore application is an area of research and understanding where still many unsolved problems are present. . This paper contains principles of underwater welding, types of underwater welding, advantages and disadvantages of underwater welding and recent trends in research works are taken to enhance welding technology and possessions of underwater welds. This paper also contains conventional and advanced underwater welding techniques.
Key words: Underwater welding; wet welding; dry (hyperbaric) welding; SMAW; FCAW; TIG FRW
