Shielded metal arc welding (SMAW), also known as stick welding, is a common welding process that uses an electric arc to melt and join metals. In this method, a coated electrode is used, which produces a protective gas and slag as it melts. This shielding helps prevent contamination of the weld from the surrounding atmosphere. The process is versatile and can be used on various metals, including steel and iron. SMAW is often favored for its simplicity and portability, making it suitable for both indoor and outdoor applications. It is widely used in construction, repair, and fabrication industries.
