In this type, about 35% in weight of
the coating is titanium dioxide (TiO2) facilitates arc ignition,
makes it possible to work with a soft arc and reduces spatter.
This electrode type is used for general purposes where good welding
properties are required.
This is the universal electrode which may perform welding in every
position, using AC or DC current.
The main properties of rutile type electrodes are as follows:
- Suitable mechanical properties of weld metal,
- Weld beam profile with good appearance due to slag properties,
- Ability to perform welding in all position,
- Easy slag removal
Rutile electrodes can have different coating thick nesses.
The molten weld metal is carried into the work piece through the
arc in the form of drops that become thinner as the coating becomes
the coating thickness positively affects the mechanical properties
of the weld.
This type of coating forms a fast-freezing slag that completely
covers the weld beam, it is rather thick and brownish black.
The properties of the slag depend o the amount and type of the substances
that make up the coating.
