E7018 stick electrodes are designed to operate with either a power source that provides either an AC or a DC (electrode positive-EP or electrode negative-EN) current..
Tungsten: Tungsten is the most popular type of arc welding rod because it's durable and produces consistent heat.
It's also the most expensive.
Copper: Copper is a good option if you need a rod lighter than tungsten but still produces a strong weld.
It's also less expensive than tungsten..
The most common types of steel welding rods are mild steel, low alloy steel and stainless steel.
Depending on the type of work being performed steel welding rods are available with or without a flux coating..
Some common welding consumables are stick electrodes, solid wires, and flux-cored wires that are widely used in Gas Metal Arc Welding (GMAW), MIG welding, flux-cored arc welding (FCAW), and Electroslag welding (ESW)..
Tungsten: Tungsten is the most popular type of arc welding rod because it's durable and produces consistent heat.
It's also the most expensive.
Copper: Copper is a good option if you need a rod lighter than tungsten but still produces a strong weld.
It's also less expensive than tungsten..
The classification of welding electrodes takes into account factors such as the electrode metal, flux coating, current utilized, welding position, performance traits, chemistry, and mechanical properties of the weld metal, among others..
Tungsten: Tungsten is the most popular type of arc welding rod because it's durable and produces consistent heat.
It's also the most expensive.

Simply put, a welding electrode is a type of welding rod.
Sometimes a welding rod melts permanently into the materials being welded.
Other times, it does not.
Interestingly, certain methods like Stick welding often cause the wire to melt into the weld materials.
The chart below covers all of the most used welding rods like E6010, E6011, E6013, E7018, etc.
Choice of a stick welding electrode is often specified in the Welding Procedure Specification (WPS), but if you are new to stick arc welding, or the job doesn't define the electrode, this guide will help you make the right choice.
