Coated Electrode. A coated electrode is made of a metallic wire (called core wire) coated uniformly with flux material. While fluxing, the electrode about 20 mm of its length is left bare at one end for mounting it into the electrode holder. The flux material used for coating of the electrode is a bad conductor of electricity.

Rutile welding electrodes contain a high proportion of titanium oxide (rutile) in the coating. Titanium oxide promotes easy arc ignition, smooth arc operation and low spatter. These electrodes are general purpose electrodes with good welding properties. They can be used with AC and DC power sources and in all positions.

Depending on the main constituent of their flux, they are grouped into three categories: cellulosic, rutile and basic. All electrodes consist of a core wire (typically 2.5–6mm diameter) coated by a flux. The …

The coating of the welding electrodes takes on specific tasks during welding. The type and structure of the coating determine the melting character of the rod electrode and its welding properties. Basically, the following types of coating are distinguished: A = acid coating; R = rutile coating; RR = rutile, thick coating; RA = rutile-acid coating

A strong, tough coating. Easier slag removal. Improved deposition rate. Metal-arc electrodes may be grouped and classified as: Bare or thinly coated electrodes. Shielded arc or heavy coated electrodes. The …
