TIG vs. MIG: Which is Best for Aluminum?

When you hire an aluminum welder, they will typically choose between two methods based on the job requirements.

TIG Welding (GTAW)

  • Best For: Thin materials, aesthetic welds, automotive parts, aerospace components.
  • Pros: Highest quality welds, precise control, visually beautiful “stack of dimes” look.
  • Cons: Slow process, requires high operator skill.

MIG Welding (GMAW)

  • Best For: Thick plates, ship hulls, structural construction, trailer manufacturing.
  • Pros: Fast travel speeds, easier for long welds.
  • Cons: Higher risk of porosity, less visually appealing than TIG.

🔧 The Expert Edge: Navigating the Challenges of Aluminum Welding

These challenges are why specialized expertise is crucial when looking for an aluminum welder or a shop offering high-quality aluminum welding near me.

1. Oxide Layer: Aluminum forms a tough, ceramic-like oxide layer (Al2O3) that melts at approx 2072.C – far higher than pure aluminum’s approx 660.C melting point.

  • Solution: Use Alternating Current (AC) TIG welding. The AC cycle’s electrode positive (EP) half-cycle cleans the surface, blasting away the oxide layer to expose the molten metal beneath.

2. High Thermal Conductivity: Aluminum dissipates heat extremely quickly, making it difficult to maintain a stable weld pool and achieve deep penetration.

  • Solution: Employ higher amperage settings and fast travel speeds. For thicker sections, preheating the workpiece slightly can help maintain the necessary welding temperature.

3. Porosity: Molten aluminum readily absorbs hydrogen (from moisture, oil, or dirty material), which is then expelled during solidification, leading to small, trapped bubbles (porosity) that weaken the weld.

  • Solution: Meticulous preparation is non-negotiable. Use a dedicated, clean stainless steel brush and non-chlorinated solvent to clean the joint immediately before welding. Ensure shielding gas (100% Argon is standard) is pure and the base metal is completely dry.

4. Hot Cracking: Certain alloys (like some 6XXX and 7XXX series) are susceptible to cracking upon cooling due to shrinkage stress.

  • Solution: Use a carefully selected filler metal (often from the 4XXX or 5XXX series) that lowers the cracking susceptibility of the weld zone chemistry.

How to Get the Durable Flux-Core Weld?

flux-core welds

Welding is no less than a heartbeat to many industry sectors, like construction, multi-scale manufacturing, even electricals and electronics and so on. Its versatility and usage require the process to be as perfect as possible. To ensure proper adhesion and lasting strength, flux-core weld fits as a powerful, versatile, and ideal for thicker metals.

Types of welding include Shielded Metal Arc Welding, Gas Metal Arc Welding, Gas Tungsten Arc Welding, Flux-Cored Arc Welding, Resistance Welding, Submerged Arc Welding, and so on. Flux-Core Weld stands out amongst these. Let us dive into this:

  1. Understand the Importance of Flux-Core Welding

Flux-core welding is not merely a technique, it’s a synergy of chemistry and control. It employs a hollow wire lined with flux, which acts as both shield and enhancer. This internal flux acts like a protective layer for the molten pool from atmospheric contamination while deepening penetration into the metal. What sets flux core welding apart is its notable resilience; flux core welding thrives where other methods falter, amidst gusts, grit, and the raw unpredictability of open-air workspaces.

Unlike traditional MIG welding, it demands no external gas shield, making it a favorite among welders who refuse to pause for the weather. Yet, balance is the quiet backbone of mastery here.

  1. Preparation: The Foundation of Strength

There’s a saying we live by at Minhas Welding “The weld begins long before the spark.” Every welding technique starts with meticulous preparation. The base metal must be immaculate, freed of oil, rust, mill scale, and paint. Impurities are the saboteurs of structural integrity; they trap gas and birth porous, brittle joints.

For thicker metals, beveling the edges before the weld ensures a deeper, stronger connection. The secret? Patience. Proper cleaning and edge work may feel tedious, but they are the quiet rituals that decide whether your weld stands proud, or fails under pressure.

  1. Selecting the Right Flux-Cored Wire for flux-cored wire electrode

Your wire is not just a consumable; it’s the heart of the operation. Choosing it without care is like choosing a foundation without checking the soil. Flux-core wires come in two main types:

  • Self-Shielded (FCAW-S): The warrior of the outdoors, built for resilience where shielding gas would falter in the wind. Ideal for rugged, on-site projects and heavy fabrication.
  • Gas-Shielded (FCAW-G): The artisan’s choice, offering cleaner welds, less spatter, and smoother aesthetics. Best used in sheltered workshops and structural builds.

Each wire type has its calling. Mild steel, stainless, and galvanized metals all demand specific compositions. A cheaper wire might save you cents now, but cost you stability later. Always pair your wire to your metal, not the other way around.

Here is the method that sheds light on how the flux-core method works. With steady hands and understanding of the technique, a welder can surely take care of it perfectly well.

  1. Refining the Technique – Where Science Meets Craft

Flux core welds reward patience and punish haste. The art lies in the angles and the rhythm. Maintain a steady angle, typically between 10° and 15°, depending on whether you push or drag the bead. Travel too fast, and your weld thins out, becomes brittle, and hollow. Move too slow, and it piles up, uneven and spattered.

Keep the arc length consistent, especially with Flux-cored arc welding; this invisible thread decides your weld’s purity. A long arc invites porosity, while a short one chokes the puddle. Skilled welders don’t just see the puddle, they listen to it. The hum, the hiss, the glow, all tell stories of temperature and fusion. At Minhas Welding, our craftsmen read those signs like seasoned storytellers reading between the lines.

  1. The Role of the Environment

Even though flux-core welding was born to brave the elements, nature still has a say in your results. Harsh wind, moisture, and biting cold can warp even the best work. Create wind barriers when possible, and always store your wires in a dry, temperature-stable space. Moisture in your wire means contamination in your weld.

A grounded, clutter-free workspace is another quiet ally. It guarantees consistent arcs and wards off erratic weld lines. Welding is as much about atmosphere as it is about technique, the right environment amplifies your control.

  1. Inspection and Integrity Testing

The weld’s true worth reveals itself under scrutiny. Once your bead cools, examine it with an unflinching eye. Cracks, undercuts, or incomplete fusion are warnings, not mere blemishes. For critical structures, conduct bend or impact tests to ensure endurance.

At Minhas Welding, every joint undergoes rigorous inspection. We believe strength isn’t what you see, it’s what you prove. Our welds don’t just need to look solid; they must endure storms, time, and tension. That’s the creed that separates craftsmanship from convenience.

  1. Skill Over Shortcuts

Durability isn’t an accident, it’s the child of discipline. In welding, there’s no “autopilot.” Robotic Machines can’t replace instinct. Every adjustment, every pass, is a conversation between human intuition and molten metal.

At Minhas Welding, we don’t chase speed; we chase perfection. From structural frameworks to intricate fabrications, we invest in precision and pride. The truth is simple: shortcuts may build fast, but mastery builds forever.

Do You Need to Weld Corrugated Metal Sheets?

corrugated metal sheets

When working with corrugated metal sheets, one question often sparks debate among builders and homeowners alike, do you actually need to weld them? Whether you’re building a shed in Alberta, roofing a cottage in Toronto, Ontario, or putting up siding in British Columbia, the method you choose impacts cost, strength, and long-term durability.

Let’s explore when welding makes sense, when it doesn’t, and how Canadian weather, building codes, and materials influence your choice.

What are Corrugated Metal Sheets and Their Uses

Corrugated metal sheets are thin, wavy-patterned steel or aluminum panels known for their strength, flexibility, and corrosion resistance. The rippled design increases rigidity while keeping weight low, perfect for roofing, siding, fencing, and even modern interior designs.

In Canada, corrugated steel is especially popular for:

  • Residential roofing and siding – handles snow, wind, and temperature swings.
  • Agricultural buildings – barns, storage sheds, and stables.
  • Commercial and industrial structures – warehouses, workshops, and factories.

Because Canada experiences extreme weather conditions, from icy winters to coastal salt air,. choosing the right material and installation method is key to preventing leaks, rust, or premature wear.

Welding vs. Non-Welding Installation Methods

What Welding Means in This Context

Welding fuses metal sheets together by heating them until they melt and bond. Common methods for corrugated steel include MIG (Metal Inert Gas) and arc welding. Welds create strong, permanent joints ideal for structural or load-bearing applications, such as steel frames or industrial supports.

However, welding corrugated sheets is tricky. The thin gauge (usually 26-gauge to 29-gauge) means they can easily warp, burn through, or distort under heat if not done precisely. It also requires skill, special equipment, and safety precautions.

Alternative Fastening Methods

For most Canadian construction projects, welding isn’t necessary. Instead, contractors use:

  • Self-drilling screws with rubber washers (most common).
  • Rivets for tight seams or decorative finishes.
  • Clips and brackets for metal-to-frame installations.
  • Sealants or adhesives in weatherproofing and lightweight applications.

These methods are faster, safer, and easily reversible, allowing for maintenance or panel replacement without cutting or re-welding.

Cost, Time, and Labour Comparison

Method

Skill Level

Labour Time

Cost

Best For
Welding Advanced High $$$ Structural frames, thick panels
Screws / Fasteners Beginner–Intermediate Low $ Roofing, siding, walls
Rivets Intermediate Medium $$ Decorative, detailed joints
Adhesives / Sealants Beginner Low $ Temporary or interior installs

In short: for most Canadian homeowners, welding isn’t worth the extra time or expense.

Do You Need to Weld Corrugated Metal Sheets?

The short answer: rarely.

Welding corrugated metal sheets is typically reserved for heavy-duty industrial or structural applications. For roofing, siding, or fencing, you’ll almost always use fasteners instead.

When Welding Makes Sense

  • Building structural frameworks or supports.
  • Repairing thick steel panels or joining to beams.
  • Working on custom fabrication (like welded art or industrial decor).

When You Don’t Need Welding

  • Installing roofing panels (standard for homes across Canada).
  • Building sheds, barns, or garages using pre-drilled sheets.
  • Projects involving galvanized or pre-painted panels (heat damages the finish).

Canadian building codes don’t require welding for metal roofing or siding. Instead, they emphasize secure fasteners, correct overlaps, and proper sealing to withstand snow loads and moisture.

Practical Insights for Canadian Installers and Homeowners

  • Choose the right gauge – For roofing, 26-gauge corrugated steel is ideal; it’s durable enough to handle snow yet light for easy installation.
  • Pick weather-resistant coatings – Galvanized or galvalume coatings help prevent rust in humid or coastal regions.
  • Mind the overlap – Panels should overlap at least one ridge horizontally and six inches vertically.
  • Fasten correctly – Always drive screws through the flat section of the panel, not the ridge, to prevent leaks.
  • Avoid welding galvanized steel – It releases toxic fumes; always work in ventilated spaces if welding is absolutely required.
  • Inspect yearly – Check screws, washers, and sealant lines after each winter to prevent rust or loose panels.

Pro Tip: For quick, professional results, most Canadian contractors use self-sealing screws and avoid welding altogether. It’s faster, cleaner, and safer, especially in cold weather.

Where to Buy Corrugated Metal Sheets in Canada?

Cost & ROI Considerations

Here’s what to expect when budgeting your project in Canada: (rough estimates)

  • Corrugated steel sheets: CAD $5 – $10 per sq ft (depending on gauge and finish)
  • Installation with fasteners: CAD $2 – $5 per sq ft
  • Welding labour (if used): CAD $70 – $120 per hour

While welding may seem stronger, the return on investment is usually higher with non-welded installations. Corrugated panels fastened correctly can last 40–60 years, withstand harsh Canadian winters, and require minimal maintenance.

Expert Opinions & Real-World Example

According to Forma Steel, a leading Canadian metal manufacturer, “Corrugated panels are designed for easy installation using exposed fasteners, making welding unnecessary for most architectural or agricultural uses.”

In Alberta, one commercial farmer replaced old wood siding with corrugated galvanized panels using only screws and sealant. After six years, the structure remains watertight with no corrosion, proving that proper fastening beats welding for long-term reliability.
