Rutile Electrode
A rutile electrode consists of a stick electrode core covered with rutile and titanium dioxide. It ensures stable arc behavior and fine droplet metal transfer.
Physicochemical Mechanism of Action
The rutile electrode consists of a stick electrode core coated with rutile and titanium dioxide. The rutile reduces the voltage between electrode and workpiece, while the titanium dioxide has a stabilizing effect on the arc behavior.
Metallurgical Relevance & Welding Risks
Using a rutile electrode leads to a fine-droplet metal transfer, which raises the hardness and strength of the weld. An insufficient rutile content, however, can cause the electrode to wear out too fast or the arc behavior to become unstable, which leads to poor welding results.
Workshop Practice & Instructions
Use a rutile electrode with a titanium dioxide content of at least 20% and enough rutile. Make sure the electrode is correctly coated and the arc behavior stays stable. If there are problems, check the rutile content and the coating.
