Arc Welding: Illuminating the Fusion Process
Definition and Brief Explanation of Arc Welding
Arc welding is a welding technique that utilizes an electrical arc to generate intense heat, melting the metal and creating a fusion between two or more workpieces. The arc is established between an electrode and the workpiece, creating a controlled electrical circuit. As the electrode tip comes into contact with the workpiece, the heat generated from the arc melts the metal, forming a weld pool. The weld pool solidifies as it cools, resulting in a strong bond.
Arc welding encompasses a variety of subcategories, including shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and flux-cored arc welding (FCAW). Each subcategory has its own specific characteristics and applications, but they all share the fundamental principle of using an electric arc to join metals.
