The TungStud (1) is placed onto the metal surface (2) that is to be protected. To protect the weld pool a ceramic ferrule (3) is placed around it.

When an electric current is applied, the TungStud raises up and an arc is initiated..

The arc causes TungStud and metal surface to become partly fused.

The TungStud sinks into the fused mass.

The two become completely joined.
Whenever you are welding on TungStuds, suitable protective equipment must always be worn!
