Development of filler wire for underwater welding as a repair tool for adaptation on AUV

摘要

In connection with intensive ocean development and interrelated expansion of underwater technology (oil and gas production from ocean beds, construction of offshore wind park etc.) problems of high-quality welding and cutting technology take on special significance. One of progressive line of investigation is underwater machine welding by means of filler wire. This article consider possibility of adaptation filler wire to autonomous underwater vehicles, design of self-protecting filler wire, its composition, influence of powder particle size on quality of wire and production double jacked filler wire at the Institute of Material Science of University Hannover.
