- Page 10 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.
