In welding, what is the purpose of an electrode?

To create the arc
To deposit filler metal
To hold the base metals
To protect the welder

The correct answer is: To deposit filler metal

The purpose of an electrode in welding is to deposit filler metal. When an electric current passes through the electrode, it creates an arc that melts the electrode and adds filler metal to the weld joint, helping to create a strong bond between the base metals being joined. Options A, C, and D are incorrect because the primary function of the electrode in welding is to provide filler material to the weld joint, not to create the arc, hold the base metals, or protect the welder.
