The mechanical properties and corrosion resistance of the base metal AT6 titanium alloy is studied and joints welded with electromagnetic stirring of the weldpool (EMS) are investigated in order to choose the welding method which gives joints similar in properties to that of the base metal. The mechanical properties of welded joints in AT6 alloy by the automatic, manual with SP2V filler, and with the AT3sv filler methods are determined. Results indicate that welding with EMS raises the tensile strength, ductility, and impact strength of the welded joints to the level of the base metal. The results also show that joints welded manually with AT3sv filler have high strength, low susceptibility to anodic dissolution in the zone of active potential, and the lowest corrosion rates in the media studied. It is recommended that equipment made of AT6 alloy should be welded with EMS using AT3sv filler wire.
