All About Welding Rods

A consumable electrode or welding rod does exactly what it says on the tin. When these filler electrodes are used to weld a joint, the rods melt and are consumed in the process of bridging the gap between the parent metal and the other metal part. Stick electrodes, solid wires, and flux-cored wires are some of the most common welding consumables used in GMAW, MIG welding, flux-cored arc welding (FCAW), and Electroslag welding (ESW).

Non-consumable Electrode is the second type.

A non-consumable electrode, on the other hand, maintains its integrity and does not change its properties while melting. The only reason to use such an electrode is to create and maintain an electric arc.

The fact that non-consumable electrodes are made of materials with higher melting points, such as tungsten, graphite, and carbon, is the mystery behind their solid structure after welding. However, oxidation or vaporisation can cause the non-consumable rods to deteriorate over time.

The only issue is that fillers must be manually fed while working with a non-consumable electrode. Non-consumable electrode applications include Tungsten Inert Gas Welding (TIG), Carbon Arc Welding (CAW), and Atomic Hydrogen Welding (AHW).
