MIG, TIG, Stick, and Flux Core are the four most popular welding techniques. Each transforms metalwork projects through unique processes and strengths.
These methods use different approaches, from feeding a wire with shielding gas to striking an arc with a coated rod, to join metals efficiently, cleanly, or even in tough outdoor conditions.
Each technique creates welds with distinct qualities, making them ideal for everything from car repairs to heavy-duty construction and detailed artistic work.
Understanding how these welding methods differ can help you choose the right one for your next project, whether you are aiming for speed, strength, or a flawless finish.
Are you curious about which welding technique will unlock the best results for your work? Read on to discover the key differences, advantages, and real-world uses of MIG, TIG, Stick, and Flux Core welding.
Understanding MIG vs. TIG vs. Stick vs. Flux Core Welding Techniques
Welding is a way to join metal parts together, but not all welding is the same. Let’s break down the four main welding techniques so you can see what makes each special.
What is MIG Welding?
MIG (Metal Inert Gas) welding, also called Gas Metal Arc Welding (GMAW), uses a gun that feeds a thin wire and shielding gas to melt and join metal.
It is quick, easy to learn for steel, and makes clean welds. For aluminum, MIG welding requires a spool gun and 100% argon shielding gas.
Best for: Beginners, car repairs, and home projects
Why pick MIG? It is fast, simple, and works on many metals (especially steel). For aluminum, special equipment is required.

What is TIG Welding?
TIG (Tungsten Inert Gas) welding, also called Gas Tungsten Arc Welding (GTAW), uses a non-consumable tungsten electrode and a separate filler rod. It gives you the most control and makes beautiful, smooth welds.
Best for: Art, bikes, thin metals, and projects that need to look great
Why pick TIG? It is neat, precise, and works well on aluminum, stainless steel, and many special metals.
What is Stick Welding?
Stick welding, also known as Shielded Metal Arc Welding (SMAW), uses a rod covered in special flux.
When you strike it, it creates an arc that melts the metal and the rod, joining them together. It is tough and works even on rusty or dirty metal.
While there are special electrodes for aluminum, stick welding is rarely used for aluminum due to poor weld quality.
Best for: Outdoor jobs, repairs, thick or dirty metal
Why pick Stick? It is simple, affordable, and works anywhere, even in windy or less-than-perfect conditions.

What is Flux Core Welding?
Flux Core Arc Welding (FCAW) is similar to MIG, but the wire has special flux inside that creates its own shielding gas when it melts.
No gas tank is needed if you use self-shielded flux core wire, which is great for outdoor work. Most hobbyists use self-shielded flux core.
There is also dual-shielded flux core, which uses both flux and external shielding gas, but this is mainly found in heavy industry.
Best for: Outdoor welding, fences, gates, heavy repairs
Why pick Flux Core? It works in the wind, is fast, and is great for thick steel.
Note: Flux core is generally not used for aluminum or non-ferrous metals in the U.S.

MIG vs. TIG vs. Stick vs. Flux Core: Comparing the Main Differences
Each welding technique has its own strengths and weaknesses. Comparing them side by side can help you see which one is best for your needs.
Speed and Ease of Use
Some welding techniques are faster or easier to learn than others. Knowing which ones are simple can help you get started faster.
- MIG: Fastest and easiest for beginners (especially for steel)
- TIG: Slow but gives the best-looking welds and is the most difficult to learn
- Stick: Simple setup and works in tough conditions
- Flux Core: Fast like MIG and better for outdoors
Weld Quality and Appearance
The way your weld looks and how strong it is can depend on the technique you use. Some methods make very neat welds, while others are stronger but messier.
- MIG: Clean welds, but not as neat as TIG
- TIG: Super smooth and attractive
- Stick: Strong but can look messy, with more spatter
- Flux Core: Strong, but produces more smoke and requires more cleanup
Best Places to Use Each Method
Where you weld matters too. Some methods are better for indoor work, while others are perfect for outdoor jobs.
- MIG: Indoors, garages, workshops
- TIG: Indoors, for art or detailed work
- Stick: Outdoors, farms, construction sites
- Flux Core: Outdoors, windy places, big jobs
MIG vs. TIG vs. Stick vs. Flux Core: Pros and Cons Table
It helps to see the good and bad points of each welding technique. A quick table makes it easy to compare them all at once.
|
Welding Technique |
Pros |
Cons |
|
MIG |
Fast, easy, neat |
Needs shielding gas, not for windy areas |
|
TIG |
Super neat, precise |
Slow, hard to learn |
|
Stick |
Cheap, works outdoors, on dirty or rusty metal |
Messy, more clean-up, more spatter |

MIG vs. TIG vs. Stick vs. Flux Core: Best Metals for Each Technique
Not every welding technique works the same on every metal. Some metals need special care or certain welding methods to get the best results.
Steel
Steel is one of the most common metals to weld. It works well with almost every technique.
- Best with: MIG, TIG, Stick, or Flux Core
- Great for beginners: MIG or Stick
Aluminum
Aluminum is light and needs a gentle touch when welding. TIG is preferred, but MIG can also work with a spool gun and 100% argon shielding gas.
Flux Core and Stick are generally not used for aluminum in the U.S. While special electrodes and wires exist, they are rarely used due to poor results.
- Best with: TIG (sometimes MIG with proper setup)
- Why: Needs gentle, careful welding
Stainless Steel
Stainless steel is strong and shiny. TIG and MIG are usually used for best results, especially when appearance matters. Stick welding is possible but less common for clean, attractive welds.
- Best with: TIG or MIG
Cast Iron
Cast iron is heavy and can crack if not welded carefully. Stick welding is the most common choice.
- Best with: Stick
Copper & Nickel
Copper and nickel are used in special projects. TIG welding provides the most control for these metals.
- Best with: TIG

Frequently Asked Questions
What are the 4 main types of welding?
The four main welding techniques are MIG, TIG, Stick, and Flux Core. Each uses different tools and methods to join metal pieces together. These are popular because they work for many kinds of projects and skill levels. Choosing the right one depends on your project and experience.
Which welding technique is easiest for beginners?
MIG welding is usually the easiest for beginners because it is simple to use and does not need a lot of practice to get started. Stick welding is also fairly easy, especially for outdoor or repair work. Both are good choices if you are new and want to learn quickly.
Can I use these welding techniques outdoors?
Yes, you can use Stick and self-shielded Flux Core welding outdoors because they do not need extra shielding gas and are not affected by wind. MIG and TIG are harder to use outside because wind can blow away the shielding gas that protects your weld. For outdoor work, Stick or Flux Core are the best options.
Which welding technique makes the strongest welds?
All four techniques can produce strong welds when used correctly. Stick and Flux Core are favored for heavy-duty or dirty steel, while TIG is preferred for thin, clean metals and precise applications. Weld strength depends more on technique, material, and setup than the process itself.
What kind of projects are best for each welding technique?
MIG welding is great for cars, bikes, and home repairs. TIG is perfect for art, bikes, and anything that needs to look smooth and clean. Stick welding is best for repairs, farms, and construction, especially outdoors. Flux Core is great for fences, gates, and heavy machinery, especially outside.
