What Is MIG, TIG and Arc Welding? A Simple Guide for Brisbane Projects
If you’re trying to understand the difference between MIG, TIG and Arc Welding, here’s the quick version: MIG Welding is fast and strong, TIG Welding is clean and precise, and Arc Welding is tough and reliable outdoors. Each welding method suits a different job, metal type, and level of detail. At SQ Mobile Welding, we use all three methods across Brisbane for structural work, repairs, fabrication, and commercial projects — but the right choice depends on what you’re building or fixing.
This guide breaks down exactly what MIG, TIG and Arc Welding are, how they work, what they’re used for, and how to choose the best method for your job. You’ll also see why MIG Welding is often the go-to option for speed, strength, and versatility.
What Is MIG Welding?
MIG Welding (Metal Inert Gas Welding) is one of the most common welding methods because it’s efficient, strong, and works across a wide range of applications. It uses a continuously fed wire to create the weld, making it easy to use on-site and ideal for fabrication or repair work.
How Does MIG Welding Work?
MIG Welding uses:
- A wire electrode
- Shielding gas (usually argon-based)
- A welding gun that combines both
The wire melts into the joint to form a strong bond.
When Is MIG Welding Used?
It’s best for:
- Structural steel
- Stainless steel
- Aluminium
- Frames and metal structures
- General fabrication
- Trailers and vehicle components
- Gates, fences, and metal frames
Why MIG Welding Matters for Brisbane Jobs
Brisbane conditions — heat, humidity, and outdoor work — demand welding that’s reliable and clean. MIG Welding is ideal because it handles thicker metals, speeds up fabrication, and allows strong welds without slowing down productivity.
SQ Mobile Welding performs MIG Welding daily for industrial, commercial, and residential jobs across Brisbane. We bring the equipment on-site, complete the welds cleanly, and leave you with strong, durable results.
What Is TIG Welding?
TIG Welding (Tungsten Inert Gas) is the method used when appearance, precision, and quality matter most. TIG uses a tungsten electrode and separate filler rod, giving the welder more control and producing cleaner, finer welds.
How Does TIG Welding Work?
TIG Welding involves:
- A tungsten electrode
- A filler rod added by hand
- Inert gas shielding (usually argon)
It’s slower than MIG Welding, but the finish is often superior.
Best Uses for TIG Welding
TIG works well with:
- Thin metals
- Stainless steel
- Aluminium
- Brass, copper, and alloys
- Architectural metalwork
- Detailed fabrication
- Custom jobs where looks matter
Why Choose TIG Welding?
If you need a weld that’s neat, smooth, and visually clean, this is the method. It’s used for high-end projects where quality is more important than speed. For example, custom handrails, decorative metal pieces, and precision pipework all benefit from TIG Welding.
SQ Mobile Welding often uses TIG for architectural welding and detailed commercial fabrication, especially when the finished result is visible.
What Is Arc Welding?
Arc Welding (Stick Welding) is the tough, reliable method suited for heavy-duty and outdoor projects. It uses a consumable electrode coated in flux, which creates a protective gas cloud during welding.
How Does Arc Welding Work?
Arc Welding uses:
- A flux-coated rod
- An electric current that melts the rod
- A shielding layer created by flux
This protects the weld from contamination.
Where Arc Welding Performs Best
Arc is ideal for:
- Rusty or dirty metals
- Outdoor repairs
- Structural steel
- Farm equipment
- Heavy industry
- Remote or hard-access jobs
Why Arc Welding Is So Practical
Brisbane job sites often involve exposure to weather, dirt, and less-than-perfect surfaces. Arc Welding is a strong, durable method that still works even when conditions aren’t ideal. It’s a favourite for fast repairs or rural jobs.
What’s the Difference Between MIG, TIG and Arc Welding?
If you're comparing the three, here’s the simplest way to understand them:
| Welding Type | Best For | Strength | Speed | Appearance |
| MIG Welding | Structural work, general fabrication | High | Fast | Good |
| TIG Welding | Precision and clean finishes | Very High | Slow | Excellent |
| Arc Welding | Outdoor, heavy-duty, dirty metals | High | Medium | Fair |
The short version:
- MIG Welding = strong + efficient
- TIG Welding = professional finish + precision
- Arc Welding = reliable in tough conditions
At SQ Mobile Welding, we work with all three every day and choose the method that gives you the strongest, cleanest and most cost-effective result.

FAQs About MIG, TIG and Arc Welding
1. What is MIG Welding best for?
MIG Welding is best for fabrication, structural metalwork, frames, and thicker metals. It’s fast, strong, and ideal for most on-site jobs.
2. Is TIG Welding better than MIG?
Not better — just different. TIG offers a cleaner finish and higher precision, but MIG is faster and more versatile for general fabrication.
3. When should Arc Welding be used?
Arc Welding is ideal outdoors or on dirty, rusty, or heavy-duty metals.
4. Which welding method is strongest?
All three are strong when done correctly, but TIG is often the strongest for precision work, and MIG is the strongest for thicker metals.
5. Do I need to choose the method myself?
No. We assess your project and choose the method that delivers the safest and most durable result.

Why SQ Mobile Welding and Mobile Camera Security Make the Perfect Collaboration
At first glance, a mobile welding company and a camera technology business might seem worlds apart, one works with steel and fabrication, the other with circuits and connectivity. But when it comes to building mobile CCTV trailers, these two skills fit perfectly together.
Through its ongoing collaboration with Mobile Camera Security, SQ Mobile Welding in Brisbane has created one of the most efficient end-to-end manufacturing setups in Australia. Their partnership blends the strength of high-quality mobile welding with advanced system integration, resulting in rugged, reliable CCTV trailers built for real-world conditions.
How Mobile Welding Shapes the Foundation of Every CCTV Trailer
Every mobile CCTV unit starts with a solid frame, and that’s where mobile welding comes in. SQ Mobile Welding fabricates the steel chassis, mast mounts, brackets, and protective housings that make up the structural backbone of each trailer.
This service includes:
- Heavy-duty steel, aluminium, and stainless fabrication
- Chassis design and custom frame builds
- Precision welding for load-bearing components
- Weatherproof finishing and compliance with Australian towing standards
This structural work ensures every trailer is safe, durable, and designed to withstand harsh Australian environments, from mine sites to remote farms.
How the Collaboration with Mobile Camera Security Strengthens the Product
While SQ Mobile Welding handles the fabrication, Mobile Camera Security contributes the technical expertise, installing power systems, wiring, cameras, and connectivity. Working together, the two teams coordinate from design through to final assembly.
The result is:
- Faster production times
- Seamless fit between frame and electrical systems
- Reduced downtime or rework
- Stronger, more efficient builds
This collaboration means SQ Mobile Welding can deliver not just fabrication, but complete, ready-to-deploy trailers, all built and tested locally in Brisbane.
Why Collaborating Beats Outsourcing
Traditional manufacturing often splits fabrication and electronics between different companies, creating communication gaps and delays. The SQ Mobile Welding partnership model eliminates that.
Here’s what this joint approach achieves:
- Better quality control – both teams inspect and sign off at every stage
- Custom flexibility – each build can be modified quickly to suit the client’s needs
- Shorter lead times – reduced back-and-forth between suppliers
- Improved reliability – no weak points between structural and electrical systems
By collaborating directly, SQ Mobile Welding ensures every project stays on schedule and every trailer leaves the workshop ready for long-term use.
