How Does Shielded Metal Arc Welding (SMAW) Work?

Shielded Metal Arc Welding (SMAW) works by creating an electric arc between a consumable electrode and the workpiece. The process begins when the welder strikes the electrode against the metal surface, establishing an arc. This arc generates intense heat, melting both the electrode and the base metal.

The electrode consists of a metal core covered with a flux coating. As the electrode melts, the flux disintegrates. It creates a protective gas and a layer of molten slag. This gas shields the molten weld pool from contamination, while the slag solidifies on top of the weld, preventing oxidation.

The welder moves the electrode along the joint, allowing the molten metal to fuse with the base material. This action forms a strong bond once the weld cools and solidifies. The welder must maintain the correct arc length and travel speed to ensure quality.

In summary, SMAW functions by using an electric arc to melt the electrode and metal, forming a weld protected by gas and slag. This method is versatile and can be used on various materials and positions.
