3.1.2 Function of the Stick Electrode Coating

Stabilization of the
arc and lonization
of the arc space

Protection of the weld
metal from atmospheric
oxygen and nitrogen

This protection is achieved by the generation of shielding gases and slag during the
melting of the electrode.

Compensation of alloy burn-off.
