Manual Arc Welding is a process that uses an electric arc to melt and join metal pieces together. In this technique, a welding rod is used as both an electrode and filler material. The heat generated by the electric arc causes the metal to melt, allowing it to fuse with the base materials. This method is commonly used in various industries due to its versatility and effectiveness. Welders can control the welding process manually, making it suitable for different positions and types of metals. Safety precautions, such as wearing protective gear, are essential to prevent injuries from sparks and intense light.
