If you're new to welding—or have been around it for a while—you’ve probably heard about MIG, TIG, and Stick welding. But knowing which one to use, and when, can be confusing. Each process has its strengths, weaknesses, and ideal applications.
In this guide, we’ll explain how MIG, TIG, and Stick welding work, what makes them different, and how to choose the right one for your next project—whether you're working in the garage, tackling home repairs, or doing serious fabrication.
MIG, TIG, and Stick Welding: A Quick Overview
Before we dive into the details, here’s a brief look at what each welding method is all about:
MIG Welding (Metal Inert Gas)
MIG welding uses a continuous wire electrode fed through a gun. An electric arc melts the wire and the base metal while a shielding gas (usually argon or an argon mix) protects the weld from contamination. MIG is easy to learn, efficient, and ideal for beginners and DIYers. It’s commonly used for thin metal sheets, auto repairs, and home improvement projects.
TIG Welding (Tungsten Inert Gas)
TIG welding uses a non-consumable tungsten electrode and a separate filler rod (if needed). It provides a precise and clean weld, making it the go-to choice for aluminum, stainless steel, and applications where appearance matters. While it takes more skill and patience, TIG produces top-tier weld quality.
Stick Welding (Shielded Metal Arc Welding)
Stick welding uses a coated metal rod (electrode) that creates its shielding gas as it burns. It’s rugged, simple, and works well in outdoor or dirty environments where wind or rust might be a problem. It’s perfect for structural work, farm repairs, and heavy-duty metal.
How Each Welding Method Works (Step-by-Step)
Understanding the basic operation of each welding style helps you get better results and avoid common mistakes.
MIG Welding: How to Use It
-
Set Polarity: Use DCEP (Direct Current Electrode Positive).
-
Choose the Right Gas: Typically 75% Argon and 25% CO₂.
-
Adjust Wire Feed & Voltage: Match your settings to the material thickness.
-
Welding Technique: Maintain a slight push angle (10–15 degrees), and move at a steady speed for consistent welds.
-
Watch Out For: Excess spatter, poor wire feed, or incorrect gas flow can affect your weld quality.
TIG Welding: Best Practices
-
Prepare the Electrode: Use a sharp tungsten tip (e.g., 2% thoriated).
-
Arc Start: Use high-frequency or lift start—avoid touching the electrode to the workpiece.
-
Add Filler Manually: Hold the torch at 10–15 degrees and feed the filler rod into the weld puddle carefully.
-
Tips: Keep your torch steady, ensure smooth gas flow, and avoid overheating the workpiece.
Stick Welding: The Basics
-
Choose the Right Electrode: Common options include E6013 and E7018.
-
Polarity Settings: Depends on the electrode—check the packaging.
- Striking an Arc: Tap or scratch the rod to start the arc, then maintain the right arc length (about the diameter of the rod).
- Keep It Steady: Control travel speed and angle for cleaner welds.
When to Use Each Welding Type
Each welding process shines in specific situations. Here’s how to choose the right one based on what you’re working on:
MIG Welding: Best for Home Repairs and DIY Projects
If you're fixing up furniture, working on car panels, or crafting metal decor, MIG welding is fast, clean, and beginner-friendly. It’s ideal for thin materials and gives you good-looking results with less hassle.
TIG Welding: Best for Precision and Appearance
When weld quality and appearance matter—like on stainless steel kitchen equipment, aluminum bike frames, or motorcycle tanks—TIG is the way to go. It’s great for intricate, high-precision jobs.
Stick Welding: Best for Outdoor and Heavy-Duty Work
Working on a farm? Repairing structural steel or gates? Stick welding doesn’t need shielding gas, so it handles wind, rust, and dirt like a champ. It’s perfect for tough environments and thick materials.
