Electrodes used in arc welding processes are classified as consumable or non - consumable. Filler metal is always added when consumable electrodes are used and never added when non-consumable electrodes are used: a) True b) False

Answer: False

Explanation:

Electrodes used in arc welding processes are classified as consumable or non - consumable electrodes.

In consumable welding process the electrode itself undergoes melting when it is near the weld pool. Hence it gets consumed during the welding process. Additional filler material is not needed in the case of consumable electodes.

In case of non consumable electrode, additional filler material is required. hence Filler metal is always added when non consumable electrodes are used and never added when consumable electrodes are used.
