Sažetak
This paper presents an experimental study of influence of shielding gas composition on TIG produced weld bead geometry and its corrosion resistance. Short overview of properties, application and weldability of Titanium was provided in the introduction of the paper. Within the framework of the experimental work, four bead on plate welds were produced using two different shielding gases (EN ISO 14175: I1 and EN ISO 14175: I3) and two welding speeds (v(1) = 9 cm/min, v(2) = 15 cm/min). Influence of shielding gases was investigated by analysing weld bead geometry and corrosion resistance testing. Weld bead geometry analysis showed that shielding gas has a significant influence on the penetration and width. Using EN ISO 14175: I3 as shielding gas resulted in larger penetration and width of the weld bead when welding with both welding speeds. Corrosion testing implicates that higher heat input results in a lower corrosion resistance of the welded joint.
