Electrodes—also known as electrorods—are a vital part of the welding process. Made from metal wire or rods, they conduct electricity to create the heat needed for welding.
Varying Purposes for Electrodes
Some electrodes are consumable and melt into the weld, while others are non-consumable and are used only to create the welding arc. Selecting the proper electrode directly impacts weld strength, quality, and performance.
Electrodes Protect the Molten Weld
Welding electrodes are classified by the American Welding Society (AWS) using codes such as E7018, which identify strength, coating type, and current compatibility. The electrode coating protects the molten weld from contamination and improves arc stability.
Reliable Coatings from WestBay
Common coating types include rutile for smooth, low-splatter welds; cellulosic for deep penetration; basic for high-strength applications; and acid coatings for clean, high-quality welds on non-ferrous metals. Westbay Gases can help you choose the right electrode for your specific welding needs.
