Beginner’s Guide to Shielded Metal Arc Welding – PrimeWeld
Shielded metal arc welding is an electric arc welding process. It uses fixed length, consumable electrodes that come covered with flux. When this flux burns at the arc, it forms a gas shield protecting the molten weld metal from the elements. Other arc processes like MIG and TIG also protect the arc -- with supplied gas rather than created gas.
