If you’ve been around welding for a while or are just starting, you’ve probably heard both terms: arc welding and stick welding. It can be a little confusing at first because, technically, stick welding is a type of arc welding. But in everyday conversation, many people use “arc welding” to refer to the broader category and “stick welding” as a specific process within that category.

I’ve worked with both methods, and while they share some similarities, they also have key differences that matter depending on the job. If you’re wondering whether to use stick welding or another form of arc welding for your project, let’s break it down in a way that makes sense.
Understanding Arc Welding
Arc welding is a broad term that refers to any welding process that uses an electric arc to generate heat and fuse metals. The arc is created between the workpiece and an electrode, which can be either consumable or non-consumable. The intense heat from the arc melts the metal and forms a weld.
Arc welding includes several different methods, such as:
- Stick welding (Shielded Metal Arc Welding or SMAW)
- MIG welding (Gas Metal Arc Welding or GMAW)
- TIG welding (Gas Tungsten Arc Welding or GTAW)
- Flux-cored arc welding (FCAW)
- Submerged arc welding (SAW)
Each of these has its own advantages and best-use scenarios, but they all rely on the fundamental principle of an electric arc melting metal to create a strong bond.
What Is Stick Welding?
Stick welding, or Shielded Metal Arc Welding (SMAW), is one of the oldest and most widely used forms of arc welding. It’s called “stick welding” because it uses a stick-shaped electrode that is coated in flux. This flux melts and creates a shielding gas that protects the weld from contaminants in the air.
This method is known for its versatility and durability, making it a favorite for outdoor welding, structural work, and repairs. Since it doesn’t require external gas like MIG or TIG welding, it works well in windy or dirty environments.
Differences Between Arc Welding and Stick Welding
Since stick welding falls under the arc welding category, the real question is: how does it compare to other arc welding processes? Let’s look at the major differences.
| Feature | Arc Welding (General) | Stick Welding (SMAW) |
|---|---|---|
| Definition | Any welding process using an electric arc | A specific type of arc welding using a flux-coated stick electrode |
| Electrode Type | Consumable or non-consumable | Always consumable |
| Shielding Method | Can use gas or flux | Uses flux from the electrode coating |
| Equipment Needed | Varies by process | Simple machine, electrode holder, ground clamp |
| Skill Level | Some methods are easier (MIG) or harder (TIG) | Requires practice but is beginner-friendly |
| Portability | Some processes need gas tanks (MIG/TIG) | Very portable – no gas required |
| Best For | Varies – industrial, precision, and automated welding | Structural work, outdoor welding, repairs |
| Cleanliness | Some methods are clean (TIG/MIG) | Produces slag and spatter |
Strengths of Stick Welding
One of the biggest reasons stick welding is still so popular is its toughness. It’s often the first choice for heavy-duty applications because it creates strong, deep welds. Here’s why stick welding is a great option:
- Works in rough conditions – No need for shielding gas means it’s great for outdoor welding, even in the wind.
- Affordable – Stick welding machines are simple and cost less than MIG or TIG setups.
- Handles thick metal well – It’s great for heavy-duty applications like structural steel and pipe welding.
- Works on rusty or dirty metal – Unlike MIG and TIG welding, stick welding doesn’t require a perfectly clean surface.
Where Stick Welding Falls Short
As great as stick welding is, it does have some downsides compared to other arc welding methods.
- Produces a lot of slag – The flux coating creates slag that must be chipped away after welding.
- More spatter – Stick welding can create a lot of sparks and spatter, requiring more cleanup.
- Not great for thin metals – Stick welding can easily burn through thinner materials.
If you’re working on automotive repairs, detailed fabrication, or stainless steel projects, you might be better off using MIG or TIG welding, which provide cleaner, more precise welds.
Arc Welding Methods Compared to Stick Welding
To help you understand where stick welding fits in, let’s compare it to other popular arc welding methods.
Stick Welding vs MIG Welding
MIG welding (Metal Inert Gas welding) uses a wire-fed electrode and shielding gas. It’s great for clean, fast welds on thinner metals. However, it requires a gas tank, so it’s not as portable as stick welding.
- Stick welding is better for outdoor welding and dirty metals.
- MIG welding is better for clean metals, thinner materials, and production work.
Stick Welding vs TIG Welding
TIG welding (Tungsten Inert Gas welding) is one of the most precise welding methods. It uses a non-consumable tungsten electrode and a separate filler metal, with shielding gas protecting the weld.
- Stick welding is faster and easier to learn.
- TIG welding produces cleaner and more precise welds but is much slower and requires more skill.
Stick Welding vs Flux-Cored Welding
Flux-cored arc welding (FCAW) is similar to MIG welding but uses a flux-filled wire instead of a shielding gas. It’s commonly used in construction and heavy fabrication.
- Both stick welding and flux-cored welding work well outdoors.
- Stick welding is simpler and doesn’t require a wire feeder.
- Flux-cored welding is better for high-production work and thicker materials.
Choosing the Right Method for Your Project
If you’re wondering which method to use, it depends on what you’re welding.
- For farm equipment, fences, or general repairs? Stick welding is a solid choice.
- For automotive work or clean indoor welding? MIG or TIG welding is better.
- For thick structural steel? Stick welding or flux-cored welding is the way to go.
- For precise, high-end welds? TIG welding is best.
Stick welding is one of the most versatile and reliable arc welding methods, but if you’re doing production work or need clean welds, other forms of arc welding may be a better fit.
Conclusion
Stick welding is just one of many arc welding methods, but it stands out because of its simplicity, affordability, and ability to handle tough welding conditions. If you need something that works outdoors, on thick metal, and in rough environments, stick welding is hard to beat.
However, if you want cleaner, faster, or more precise welds, other arc welding methods like MIG or TIG might be a better choice. The key is knowing what works best for your specific project.
If you’re just getting started, stick welding is a great place to begin because it teaches fundamental skills that apply to all welding techniques.
Frequently Asked Questions
Is stick welding the same as arc welding?
Stick welding is a type of arc welding, but arc welding includes many different methods, like MIG and TIG.
Why is stick welding better for outdoor work?
Stick welding doesn’t require a shielding gas, so wind and weather don’t affect it as much as MIG or TIG welding.
Is MIG welding easier than stick welding?
Yes, MIG welding is easier for beginners because it has a continuous wire feed and produces cleaner welds.
Can you weld aluminum with stick welding?
Technically, yes, but it’s difficult. MIG or TIG welding is a better choice for aluminum.
What is the strongest type of welding?
It depends on the application, but stick welding and flux-cored welding are often used for heavy-duty structural work because of their deep penetration and strength.
