Welders use different tools for different welding jobs. Depending on the material you’re welding, the purpose of the weld, and even the environment you’re working in, you’ll need to use specific tools to get good results. Understanding which tools and welding processes to use, and when, is one of the key things covered in welding training programs.
What’s the Difference Between a Welding Stick and a Welding Rod?
The terms “welding sticks” and “welding rods” refer to specific types of tools, but there is some crossover. When people in the welding trade talk about welding rods, they’re referring to the broad category of welding tools, of which welding sticks are a subset.
Welding sticks and welding rods are used for different purposes:
- A welding stick is a form of welding rod used for something called Shielded Metal Arc Welding (SMAW)
- Other welding rods are used for other processes such as Gas Tungsten Arc Welding (GTAW/TIG or GTAW/MIG)
Welding rods can be consumable or non-consumable. A consumable welding rod serves two purposes. It acts as an electrode, and also melts during the welding process, serving as a filler material. In contrast, non-consumable welding rods act as a stable electrode, but don’t melt. Welders use a separate filler material which to create the bond.
While the overall welding process is similar with both welding sticks and welding rods, there are some minor differences:
- Welding sticks: Before welding, the stick is loaded into the electrode holder. When the stick comes into contact with the piece being welded, it forms an arc and generates heat. This heat melts the base metal and the electrode core. The flux coating evaporates, and this creates a shielding gas which forms a slag to protect the weld. Once the weld has cooled, the slag can be removed, leaving behind a clean weld bead.
- Welding rods: When welding with a non-consumable rod, it’s important to choose the correct type of rod for the material, and load an appropriate filler. The rod doesn’t melt, but rather maintains a continuous arc, while the filler and the base material melt to form a bond. The overal process is similar, however, and once the weld has cooled the welder will remove any slag, leaving a clean join.
How do You Become a Welder?
The best way to become a professional welder is to complete a training program that covers the practical skills required to work with different materials and tools. At the Environmental Technical Institute (ETI), we offer a comprehensive welding training program that arms learners with the theoretical and practical skills required to work in a variety of welding jobs. The program covers health and safety, welding processes and more.

Key Takeaways
What is the difference between a welding stick and a welding rod?
A welding stick is a specific type of welding rod used in Shielded Metal Arc Welding (SMAW), while “welding rod” is a broader term that includes consumable and non-consumable rods used in various welding processes.
How do welding sticks and welding rods work differently?
Welding sticks melt during the welding process and act as both the electrode and filler material, while non-consumable welding rods maintain the arc and require a separate filler material to create the weld.
How can you become a professional welder?
Completing a welding training program helps students learn welding techniques, safety procedures, and how to work with different materials and welding equipment.
