The metal core works as conductor of the current that
maintains the arc. The metal core melts and is deposited
into the weld pool.
The covering on a shielded metal arc welding electrode
is called flux. The flux on the electrode performs many
dierent functions.
These include:
Pducing a protecti gas aund the weld area
Proding fl elemen and dedize
Creating a protective slag coating or the ld as it
cools
Establishing a charactetics
Adng allng elements.
Covered electrodes serve many purposes in addition to
adding filler metal to the molten pool. These additional
functions are provided mainly by the covering on the
electrode.
