Stick Electrodes

In SMAW (shielded metal arc welding) jobs, stick welding electrodes feature a metal core that melts and fuses with material from a workpiece to form a weld. They're also known as welding rods because they feature a coating that produces shielding gas as it heats up, keeping impurities out of the weld pool. This eliminates the need for an external source of shielding gas, allowing them to be used in windy outdoor environments. A weld is formed when an arc is formed between an electrode and a workpiece, and the heat from the arc melts and fuses material from the workpiece and the electrode.
