How to choose welding electrodes?

Choosing an electrode is determined by the requirements of the welding job. These include:

Tensile strength
Ductility
Corrosion resistance
Base metal
Weld position
Polarity
Current

There are light and heavy coated electrodes. Light coated electrodes have a light coating that is applied through brushing, spraying, dipping, washing, wiping, or tumbling. Heavy coated electrodes are coated by extrusion or dripping. There are three main kinds of heavy coatings: mineral, cellulose, or a combination of the two. Heavy coatings are used for welding cast iron, steels, and hard surfaces.
