A welding electrode is a coated metal wire or rod that conducts electricity to create an arc for welding, melting the metal and acting as a filler material to join two pieces of metal.

Welding electrodes are essential components used in various welding processes, including shielded metal arc welding (SMAW), also known as stick welding. These electrodes are rods or wires that conduct electrical current to create an arc, which generates heat to melt the workpiece and form a strong joint. The electrode itself can be made of different metals, and it often has a coating that provides additional protection and influences the quality of the weld.

Welding rods, also known as welding electrodes, are essential tools used in the welding process to create a strong bond between two metal parts. These rods are typically made of a metal core surrounded by a coating designed to provide shielding gases, stabilize the arc, and protect the weld from impurities. The core metal of the rod serves as filler material, melting and bonding with the base metal during the welding process.
