Abstract

Hyperbaric dry welding is an effective way of underwater repair in offshore engineering. Though various welding methods have been attempted at home and abroad for years, problems and limitations exist. This paper conducted a systematic study on character of GMAW method in hyperbaric dry environment. Experimental study on arc characteristics and the establishment of welding process stability are both developed by means of determination of test condition and the application of High-speed camera technology. Combining with analysis of microstructure and mechanical property of welded joints, a complete technology is formed. The research has opened a new road for the development of welding technology in underwater repair engineering.
