Welding Techniques Explained: MIG vs. TIG vs. Stick
Welding is the backbone of metal fabrication, and choosing the right welding method can impact the strength, finish, and efficiency of your project. The three most common welding processes are MIG, TIG, and Stick. Each has its own strengths and ideal uses. Let’s break them down:
1. MIG Welding (Metal Inert Gas)
What it is:
Also known as Gas Metal Arc Welding (GMAW), MIG welding uses a continuously fed wire electrode and shielding gas to join metals.
Best for:
Mild steel, stainless steel, and aluminum
Projects requiring speed and efficiency
Automotive work, heavy-duty repairs, or light industrial fabrication
Pros:
✅ Fast and efficient
✅ Easier to learn for beginners
✅ Cleaner welds with less post-cleaning
Cons:
❌ Not ideal for outdoor work (wind affects shielding gas)
❌ Can be more expensive due to gas and equipment
At DSNR Fabrications:
We often use MIG welding when time is a factor, or for producing multiple consistent welds in a short time — especially on medium to large parts.
2 TIG Welding (Tungsten Inert Gas)
What it is:
Also known as Gas Tungsten Arc Welding (GTAW), TIG welding uses a non-consumable tungsten electrode and separate filler rod, with shielding gas to protect the weld.
Best for:
Thin metals, precision work, and intricate welds
Stainless steel, aluminum, copper, and exotic metals
High-end finishes (e.g., architectural, aerospace, custom art)
Pros:
✅ High-quality, precise welds
✅ Clean and aesthetically pleasing results
✅ Great for thin or delicate materials
Cons:
❌ Slower process
❌ Requires skilled hands and more experience
❌ Equipment is more expensive
At DSNR Fabrications:
We use TIG welding for projects that demand precision and craftsmanship, like custom metal components, pressure vessels, or decorative pieces.
3. Stick Welding (Shielded Metal Arc Welding)
What it is:
Stick welding uses a consumable electrode coated in flux. When melted, the flux forms a gas shield and slag to protect the weld.
Best for:
Outdoor or remote welding
Structural steel, pipelines, or heavy equipment repair
Rusty or dirty metals
Pros:
✅ Works well outdoors and in windy conditions
✅ Equipment is simple and portable
✅ Doesn’t require shielding gas
Cons:
❌ More cleanup due to slag
❌ Less precise than MIG or TIG
❌ Not ideal for thinner materials
At DSNR Fabrications:
Stick welding is a go-to technique for field repairs and structural jobs where durability and strength are more important than appearance.
Choosing the Right Technique
Each project at DSNR Fabrications is unique — which is why we choose the welding method that best matches the material, location, purpose, and quality requirements.
