18 Nov 2013 Arc Welding • Because of the versatility of the process and the simplicity of its equipment and operation, shielded metal arc welding is one of the world's most popular welding processes. 14. Basics of Arc Welding • The arc is struck between the electrode and the metal. • It then heats the metal to the melting
Shielded Metal Arc Welding. aka arc welding or stick welding. Work to be welded is connected to one side of an electric circuit (the ground cable). A metal electrode is connected to the other side (the electrode cable). These two parts of the circuit are brought together and then separated slightly. The electric current jumps
