This grade is referred to as commercially pure (CP). Typical uses are in sea water, heat exchanges, piping systems, aerospace industries. AMS specification 4951 encompasses all of the commercially pure welding wires. Titanium is a reactive metal that is sensitive to embrittlement by oxygen, nitrogen and hydrogen at temperatures above 500F. This can be provided by shielding the metal with high purity inert gas or in a chamber. Cleanliness of the joint is a major factorin producing porosity free welds. Protection of the wire at all times is required to assure cleanliness. Can be fusion welded to Zirconium, Tantalum, Nobium and Vanadium. Should not be fusion welded to Copper, Iron, Nickel, and Aluminum, as it will produce extremely brittle welds.
