If you haven't already heard of titanium weld wire, read on to discover the benefits and different applications of this metal. Learn how titanium weld wire is better than standard wire and why you should start using it. After all, welds are much stronger and more durable with titanium!
Benefits of Titanium Welding Wire
Titanium is biocompatible, and while it burns in pure nitrogen, it remains brittle at room temperature. Because of this, it is vital to protect titanium welding wire from contaminants. While the main goal is to obtain a bright silver weld, oxygen or gas contamination may render it useless. This is where proper weld preparation comes into play.
Titanium's low thermal conductivity makes it a superior weld material. Titanium requires inert gas until 700degF, but regular argon can be used. The inert gas must also be provided at the correct flow rate to avoid contamination. Titanium Welding Wire is compatible with conventional TIG processes. However, a special purge chamber must be used for TiP TiG welds.
Titanium TIG Welding Wire is highly efficient in the arc process. The process can take up to 20 minutes for a typical titanium weld. The titanium wire's arc starts and finishes more quickly, reducing the need for subsequent heat treatment. It also produces fewer hot cracks during the welding process than tungsten. Aside from its higher heat conductivity, the titanium welding wire is low in amperage, making it a good option for tube/pipe applications.
Applications of Titanium Welding Wire
While titanium is one of the hardest metals on earth, it has some advantages over other metals for welding. Titanium Alloy Welding Wire can be used to join titanium and carbon components. This metal is extremely durable and extremely heat treatable. Compared to other metals, titanium is also strong and has high creep resistance. It is usually welded in its annealed state with a matching filler wire. Below are some of the most common applications for Titanium Alloy Welding Wire.
Unalloyed titanium is the alpha phase at room temperature and transitions to the beta phase at about 8800C. Titanium grades vary in the number of impurities they contain, which can decrease the ductility of the final weld. However, Grade 2 titanium welding filler wire is used for welding titanium alloys that are dissimilar to each other. These materials are welded with matching chemistry. VBC Group produces titanium alloy aerospace welding filler wire that meets the AMS, MSRR 9500, and AWS specifications.
A titanium sponge can be crushed or sheared to make Titanium Alloy Welding Wire. Titanium welding wire feedstock is typically created by crushing and shearing larger pieces of titanium sponge. Its chemical composition and mechanical properties are comparable to that of conventional weld wire. The main difference between titanium and carbon is the mass diffusion coefficient of each material. Titanium will diffuse oxygen faster than carbon, whereas carbon will diffuse at a slower rate.
