Titanium Grade 1 also known as commercially pure titanium as it comprises of more than 99% titanium along with other elements like iron, oxygen, carbon etc. It is characterized by excellent corrosion resistance with moderate strength, low weight, high ductility and good weldability is desired. The microstructure properties are not greatly affected by thermal treatments or welding temperatures since it is single phase material substantially. Hence the mechanical properties of a good weld joint are equal to or may exceed to those of the parent metal and provide good formability.
