Welding Electrode and Rod

Definition

The Welding Electrode and Rod are the components of the welding circuit through which current is conducted between the electrode holder and the arc.

Purpose

The purpose of the welding electrode and rod is to conduct the electrical current that creates the arc needed to melt and join metals. They also often provide filler material that adds to the weld joint.

Examples of Use

• Stick Welding (SMAW): Using a consumable electrode rod coated with flux to create the weld.
• MIG Welding (GMAW): Using a continuous wire electrode fed through a welding gun.
• TIG Welding (GTAW): Using a non-consumable tungsten electrode and a separate filler rod if needed.

Related Terms

• Flux: A material used to protect the weld area from oxidation and contamination.
• Arc Welding: A welding process that uses an electric arc to melt the metals at the welding point.
• Filler Metal: Additional metal added during the welding process to help join the metals.

Notes

The choice of electrode and rod depends on the type of welding, the materials being joined, and the desired properties of the finished weld. Proper handling and storage are essential to maintain their quality and effectiveness.
