During the MMA welding process, the arc created between
the work piece and the consumable electrode rod melts the
parent metal and the filler metal in a weld pool.
The electrode’s flux coating reacts during this process
and develops into a shield gas protecting the weld bead.
Part of this reaction leaves a trail of slag which solidifies
behind the weld pool protecting the weld as it cools.
The most common varieties of electrodes are cellulosic,
rutile and basic, the latter two being the most general
purpose.
Selection of the appropriate specification electrode is
important to achieve a good quality weld. Seek guidance
if unsure of selection.
