How is the manganese range of the SA electrode noted in the AWS classification?

To determine

The method of classifying the range of manganese of electrode that is used in Submerged Arc Welding process in AWS.


Submerged Arc Welding is a type of welding process. It can be used for joining the metals which are similar or dissimilar. In this process, an arc is produced between the electrode and work material that has to be joined. The arc produces an enough heat which is used for joining of these metals. A molten weld pool is formed due to the fusion of metals. The molten weld pool is protected by using a thick layer of flux or slag which is formed by the granular fluxing. The slag prevents the molten metal to react it with the atmospheric air, and hence gives a better quality of weld.

The Submerged Arc Welding process uses a consumable electrode. The electrode used is in the form of wire. The wire is coated with the copper which prevents the electrode from the corrosion. As the melting of electrode takes place, the electrode flows to the workpiece along with the molten pool of flux. The flux gets fused with the parent molten metal and hence make a weld joint. SAW has high amount of deposition rate. The classification of electrode is prefixed with an alphabet letter E which designates electrode
