Working Animation Of Shielded Metal Arc Welding Process


Shielded metal arc welding SMAW is a welding process in which coalescence of metals is produced by heat from an electric arc maintained between the tip of a consumable electrode and the surface of the base material in the joint being welded.

This video explains about shielded metal arc welding process in detail. Which includes construction, working, advantages, disadvantages and applications of shielded metal arc welding process.Watch the video from ADTW learn:

An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric arc between the electrode and the metals to be joined.


The workpiece and the electrode melts forming a pool of molten metal (weld pool) that cools to form a joint. As the weld is laid, the flux coating of the electrode disintegrates, giving off vapors that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination.ADTW learn
