E7018 electrodes are heated before use to remove any moisture content that may have been absorbed from the atmosphere. This helps to prevent hydrogen-induced cracking in the weld metal and ensures better weld quality and mechanical properties. Heating also improves the stability and arc characteristics of the electrode during welding.

There is a coating on electrode. It absorb moisture from an atmosphere.

To remove moisture from it, we have to back that electrode up to 300 ' C.

If we dont heat this electrode, there is a chance to get discontinuity in welding.
