Electric Arc Welding is a process that uses an electric arc to melt and join metals. The arc is created between an electrode and the workpiece, generating intense heat that fuses the materials together. This method is commonly used in construction and manufacturing due to its efficiency and ability to weld thick materials. The process can be performed in various environments, including outdoors and in confined spaces. Different types of electrodes and welding techniques, such as Shielded Metal Arc Welding (SMAW) and Gas Metal Arc Welding (GMAW), can be employed to achieve specific results based on the materials and project requirements.
