Full Description

This report discusses the welding behaviors of the elements tungsten, tantalum, molybdenum, columbium, zirconium, titanium and beryllium and their alloys. For purposes of discussion, these elements have been divided into a refractory metals group comprised of the first four elements mentioned and a reactive metals group comprised of the last three elements. The refractory metals are members of Groups V-A and VI-A in the periodic table and consequently exhibit many similar properties. Property similarities among the reactive elements are not consistent since beryllium is a member of Group 11-A and titanium and zirconium are members of Group IV-A of the periodic table. Despite the group designation, all metals discussed share the common characteristic of reacting with the atmospheric gases, oxygen and nitrogen.
