Electric arc welding is a widely used metal joining process that employs electrical energy to generate heat for melting and fusing metallic components. During welding, an electric arc is established between the electrode and the workpiece, producing sufficient heat to create a molten weld pool that solidifies upon cooling, forming a strong bond. To protect the molten metal from atmospheric contamination and undesirable chemical reactions, shielding materials such as slag are utilized. Arc welding processes may use either consumable or non-consumable electrodes and can operate with alternating current (AC) or direct current (DC) power sources. The electrode functions as a conductor, transmitting electrical current to the workpiece and generating the heat necessary for fusion. Power sources for arc welding are generally classified as constant current (CC) or constant voltage (CV) systems. Current primarily influences heat input, while voltage affects arc length. Manual welding processes, including Shielded Metal Arc Welding (SMAW) and Gas Tungsten Arc Welding (GTAW), commonly employ constant current power sources to maintain stable welding conditions despite fluctuations in voltage. Understanding the principles of arc welding and power source characteristics is essential for achieving high-quality welds and optimizing welding performance in industrial applications.

In order to fuse two metal components, electric arc welding uses electrical heat to cause melting, which, when cooled, forms a solid connection. In order to protect the molten metal from exposure to the atmosphere and stop chemical reactions, slag is injected throughout this operation. A power source that creates an electric arc between the metal material and the electrode to be fused is necessary for this process. Both consumable and non-consumable electrodes, as well as alternating or direct current, are used by welders. An electrode is a conductor that creates the heat required for melting and fusing by sending electric current to the metal to be welded. Whether an electrode is consumable or non- consumable depends on the specific arc welding process being used. The electrical energy needed for the arc welding process may be obtained from a variety of power source methods. Constant voltage and constant current power sources are the most common varieties.
