Electrode Welding

Electrode welding is a widely used welding method. The welding arc occurs between the electrode and the workpiece.

The high temperature of the arc melts the electrode and the metal during welding. The material to be welded must be protected from oxygen in the air. This protection is caused by the gases released when the electrode coating burns during welding.

However, during cooling, this protection is provided by the slag formed on the seam, which is later removed. In electrode welding, the coating of the electrode is important. This can be done with an acidic, basic, rutile or cellulose coating.
