Filler Metals/Electrodes

Filler metals are alloys or pure metals that are heated to liquefy, melt and flow into the space between two close fitting parts, creating a brazed or soldered joint that meets specific requirements for strength and corrosion resistance. Welding electrodes are metal wires with baked-on chemical coatings. The rod sustains the welding arc and is the filler metal used for the joint being welded. The coating protects the metal from damage, stabilizes the arc, and improves the weld. The type of base metal being welded, the welding process and machine, and other conditions determine the type of welding electrode used.
