Q

TRUE OR FALSE: Using coated electrodes, it improves the penetration of the weld and therefore ensures a sound joint.

A

TRUE

17
Q

TRUE OF FALSE: The coating facilitates the striking of the electric arc and enables it to burn stably, thus making the electrode suitable for use with an alternating current.

A

TRUE

18
Q

TRUE OR FALSE: Using coated electrodes, this can be provided a flux for the molten weld pool from which inserts impurities and forms a protective slag which can be readily chipped off when cooled and solidified.

A

FALSE

19
Q

TRUE OR FALSE: The coating can be made at the time of manufacture in order to replace any alloying elements in the electric core.

A

TRUE

A

Undercut

31
Q

It is the metal to be welded or cut.

A

32
Q

It is produced by a low-voltage, high-amperags current jumping the air gap between the electrode and the joint to be welded.
