SMAW, or Shielded Metal Arc Welding, is a manual welding process that uses an electric arc to melt and join metal pieces. In this method, a coated electrode is used, which produces a protective gas and slag to shield the weld from contamination. This technique is commonly employed in various industries due to its versatility and effectiveness. The SMAW process is suitable for welding different types of metals, including steel and iron. It is often used in construction, manufacturing, and repair work. The simplicity of the equipment and the ability to work in various positions make SMAW a popular choice among welders.
