Titanium welding is gaining more and more popularity. Titanium welding is a quite quick process and rather easy to use instead of other welding possibilities. It means that pure titanium or different titanium alloys are welded in by a welding process. The main welding processes used for titanium welding are the gas tungsten- arc (GTAW) and the gas metal- arc (GMAW). In addition, electronic beam and also laser have been used recently for titanium welding. Moreover, titanium welding can be done by solid state processes, for example like friction welding and diffusion bonding.

Titanium welding techniques are quite similar than those used for welding nickel alloys and stainless steels. The surface has to be extremely clean as well as for other welding types to assure the best results.  In addition, for the best result it is important to use the inert gas correctly for shielding while welding titanium. Titanium weld metal characteristics can be altered by exposure in air or on the impure surface to oxygen, nitrogen or hydrogen during the welding process.

One disadvantage of titanium welding is that it cannot be welded to almost all other metals as an embrittling metallic compound arises and that will result the weld to crack.
