Abstract
In this study, commercial pure titanium sheets (ASTM Grade 2) were joined by resistance spot welding method by using different parameters (electrode force, welding current and welding time). In the welded joints; effects on weld nugget diameter, electrode dept intensity, crack type, hardness and microstructure properties of electrode force, welding current and welding time were investigated. The experimental results showed that increasing electrode force, welding current and welding time increased the weld nugget diameter and electrode dept intensity. On examination of fracture types, welding parameters were understood to be suitable for this study. It was seen that weld nugget hardness is higher than HAZ and base metal in all weld parameters. Microstructural examinations showed that the grains formed increasing welding parameters were growed and local twins were formed due to heat emerged during welding and high plastic deformation.
