What Is TIG Welding?
TIG welding Gas Tungsten Arc Welding (GTAW) is the highest-precision arc welding process. Unlike MIG, TIG uses a non-consumable tungsten electrode to create the arc; the welder manually feeds a separate filler rod into the weld pool with the other hand, while a foot pedal controls arc amperage in real time. This three-point coordination torch, filler rod, and foot pedal makes TIG the most skill-intensive arc process, and the one that produces the most precise, aesthetically refined welds.
TIG is the correct process when weld aesthetics matter, when material is thin and vulnerable to burn-through, when the alloy demands precise heat management, or when post-weld surface requirements are strict. The “stack of dimes” weld profile visible on properly TIG-welded stainless or aluminum is the result of deliberate, consistent bead placement only achievable with this process. For food-grade 316L stainless, aerospace-grade alloys, architectural visible joints, and thin-section aluminum work, TIG is the standard not an upgrade.
Canawelding is a division of CanaStruct a structural framing company operating across Ontario. Our TIG welders carry AC/DC TIG equipment, pure argon and tri-mix shielding gas, and filler rod for carbon steel, 304 and 316L stainless, aluminum, and chrome-moly on every truck.

Types of TIG Welding Services We Offer
TIG Welding for Every Application
Residential TIG Welding
Homeowners who need precision welding on visible, aesthetically important metalwork. Common residential TIG calls include stainless steel railings and balustrades, aluminum gate fabrication and repair, decorative ironwork, custom furniture, and thin-gauge stainless kitchen fixtures.
We come to your property, assess on-site, and provide a written price before any work begins. No shop drop-off no dismantling of installed metalwork.
Commercial & Food-Grade TIG Welding
Commercial kitchens, food processing facilities, breweries, and pharmaceutical environments requiring 316L stainless TIG work with post-weld passivation. We deliver the complete scope: TIG welding to food-grade finish, heat tint removal, and passivation treatment meeting 3-A Sanitary Standards where required.
Work scheduled during off-hours if required. CWB certification and WSIB clearance provided in advance for any site documentation process.
Industrial & Exotic Alloy TIG Welding
Facilities requiring precision welds on alloys that MIG cannot handle properly — titanium, Inconel, chrome-moly (4130/4140), duplex stainless, and thin-wall tubing. We respond to industrial facilities across the GTA with TIG-equipped mobile rigs and the correct filler for your specific alloy.
HSE documentation, CWB records, and weld procedure specifications available before site entry on every industrial call.
Aluminum TIG Welding (AC)
Aluminum TIG welding requires AC (Alternating Current) — the electrode-positive half-cycle provides oxide cleaning action on aluminum’s high-melting-point oxide layer. Without AC, fusion is poor. We carry AC/DC TIG equipment with 100% argon shielding gas and ER4043/ER5356 filler rod on every truck dispatched for aluminum work.
For thin aluminum sections, tight-access joints, or aesthetically visible aluminum welds, AC TIG produces far superior results than MIG spool gun.

Process Comparison
TIG vs. MIG Welding | When Does Precision Justify the Cost?
TIG welding costs 15–40% more than comparable MIG work due to slower deposition rates and higher skill requirements. That premium is justified when material demands it — thin sections, exotic alloys, food-grade finish, or visible architectural joints. When it isn’t, we’ll tell you to use MIG instead.
When to Choose TIG Over MIG
Choose TIG when: material is thin (under 3mm) and burn-through is a real risk; the alloy requires it (aluminum, titanium, Inconel, duplex stainless); the joint will be visible and aesthetics matter; the application is food-grade or pharmaceutical; or the post-weld surface must pass a strict inspection. When none of these apply, MIG is faster and cheaper for the same structural result — and we’ll tell you so when you call.
TIG Welding vs. Alternative Processes
TIG Welding (GTAW)
Manual · Non-Consumable Electrode · Precision
- Highest precision — fully manual filler rod control, finest bead quality and aesthetics
- Handles thin material from 0.5mm without burn-through risk
- Required for aluminum (AC), titanium, Inconel, chrome-moly, thin-wall stainless
- Food-grade, pharmaceutical, and architectural stainless — the standard process
- Precise foot-pedal amperage control prevents sensitization on stainless
- Significantly slower than MIG — higher cost per metre of weld
- Best for: aesthetics, precision, thin material, exotic alloys, food-grade
MIG Welding (GMAW)
Semi-Automatic · Wire Feed · Production Speed
- Faster — higher deposition rate, better for structural and production repair
- More forgiving technique — semi-automatic wire feed, easier to produce consistent results
- Works on structural steel, stainless (tri-mix), and aluminum (spool gun)
- Best for material 1.5mm and above where TIG aesthetics aren’t required
- Lower cost per hour on most structural and fabrication jobs
- Less aesthetically refined than TIG on visible or thin-section joints
- Best for: structural steel, commercial fabrication, general repair, high volume

Frequently Asked Questions
What is TIG welding and how does it work?
TIG welding (Gas Tungsten Arc Welding / GTAW) uses a non-consumable tungsten electrode to create the welding arc. The welder manually feeds a separate filler rod into the weld pool with the other hand, while a foot pedal controls amperage in real time. This three-point coordination produces the most precise arc welds possible — finer beads, better aesthetics, and compatibility with exotic alloys that MIG cannot handle properly.
Why does TIG welding cost more than MIG?
TIG welding requires more time per metre of weld — deposition rates are lower, technique demands are higher, and each pass is more deliberate. TIG typically costs 15–40% more than comparable MIG work. That premium is justified when material or application demands it: thin sections, exotic alloys, food-grade stainless, or visible architectural joints. When MIG will produce the same structural result faster and cheaper, we’ll tell you.
Is TIG welding required for aluminum?
TIG is often the best process for aluminum, particularly for thin sections, visible joints, or work requiring precise heat control. However, MIG with a spool gun is also a correct aluminum process for thicker material (3mm+) where aesthetics aren’t the priority. AC TIG is required for aluminum oxide cleaning — DC alone cannot disrupt the high-melting-point oxide layer and produces poor fusion. We assess material and application and recommend the appropriate process.
What shielding gas is used for TIG welding?
For most TIG applications — steel, stainless, aluminum — 100% pure argon is the standard shielding gas. Argon-helium blends are used on some thicker materials where deeper penetration is required. For stainless MIG (not TIG), tri-mix is used. Pure argon is carried on every truck dispatched for TIG work across the GTA.
Can you TIG weld stainless steel on-site?
Yes — on-site TIG welding for 304, 316L, and duplex stainless across Toronto and the GTA. Our mobile rigs carry the correct TIG equipment, pure argon shielding gas, and ER308L (304), ER316L (316L), and ER309L (dissimilar joints) filler rod. For food-grade 316L applications, we quote post-weld passivation as part of the full scope — not as a separate add-on after the fact.
How much does TIG welding cost in Toronto?
Precision residential TIG work typically $250–$650; commercial stainless TIG $500–$1,500+ depending on scope, grade, and post-weld treatment. Exotic alloy work (titanium, Inconel) quoted specifically after on-site assessment. No shop drop-off, no travel surcharge within our GTA service area. Written quotes for commercial and industrial clients before any work begins.
What exotic alloys can you TIG weld on-site?
Our TIG welders are experienced with titanium, Inconel, chrome-moly (4130/4140), duplex stainless, 304 and 316L stainless, aluminum (1xxx, 3xxx, 5xxx, 6xxx series), and thin-wall mild steel. If your job involves an unusual alloy, describe it when you call and we’ll confirm capability and the correct filler selection before booking. We don’t guess at filler selection on exotic alloys.
Do you do TIG welding for food processing and commercial kitchens?
Yes — food-grade stainless TIG welding is a core part of our work. We handle 316L stainless TIG with proper heat control, passivation, and surface finish for commercial kitchens, food processing equipment, breweries, and pharmaceutical fabrication. Work can be scheduled during off-hours to minimize production disruption. We advise on 3-A Sanitary Standard compliance for weld profiles and post-weld treatment before quoting.
How quickly can you dispatch a TIG welder to my site?
For standard booked jobs, 1–3 business days across the GTA. For urgent or time-critical work, call us directly at (647) 641-0550 rather than submitting a form. We provide an honest estimated arrival time and hold to it — we don’t give four-hour windows and go silent.
