Heavy Equipment Welding & Repair Services in the GTA
Heavy equipment welding is the repair, reinforcement, and fabrication welding performed on excavators, loaders, cranes, and trailers, using CWB-certified processes rated for high-strength steels like AR400 and Hardox. CanaWelding sends a certified mobile welder to your job site, so equipment goes back to work the same day instead of sitting in a shop queue.
What Is Heavy Equipment Welding?
Heavy equipment welding is repair, reinforcement, and fabrication welding performed on large construction and industrial machinery, including excavators, backhoes, bulldozers, loaders, cranes, and trailers. It is not the same as general metal repair. Heavy equipment is built from high-strength steels like AR400, AR500, and Hardox, and welding them without the right process and filler metal can leave a joint weaker than the base material.
CanaWelding's welders are CWB-certified under CSA W47.1, the standard that governs structural and heavy fabrication welding in Ontario. That background, combined with CanaWelding's roots as the welding division of CanaStruct Inc., an HCRA-licensed structural framing contractor, means the same rigor applied to load-bearing steel on a building gets applied to a cracked boom arm or a worn bucket lip.

Industrial Equipment and Machinery Welding
Conveyor systems, machine supports, and processing equipment welded and reinforced without a full shutdown.
Trailer and Heavy Vehicle Frame Welding
Frame, hitch, and structural repairs for dump trailers, flatbeds, and commercial fleet vehicles.
Crane and Lifting Equipment Welding
Boom sections, outriggers, and lifting attachments welded to the precision that load-bearing equipment requires.
Patch Welding vs. Build-Up Welding: The Two Types of Weld Repair
There are two major types of weld repair used on heavy equipment: patch welding and build-up welding. Patch welding cuts out a cracked, holed, or broken section of steel and welds a new patch or plate over the damage. Build-up welding deposits layers of weld metal onto a worn surface, like a bucket tooth or cutting edge, to restore the part's original dimensions.
| Patch Welding | Build-Up Welding | |
|---|---|---|
| Used for | Cracks, holes, punctures, broken frame sections | Worn bucket teeth, cutting edges, pins, and bores thinned by abrasion |
| What happens | Damaged steel is cut back to sound metal, a matching patch or plate is shaped and welded in, full penetration where the equipment is load-bearing | Weld metal, often a hardfacing alloy, is layered onto the worn surface and ground back to the original profile |
| Goal | Close the damage and restore structural integrity | Extend the part's working life instead of replacing it |
Equipment Welding Repair Cost in the GTA
Minor repairs on standard structural steel components typically range from $400 to $1,200 on-site. Equipment welding repair cost depends on the extent of the damage, the steel grade involved (AR400 and Hardox cost more in filler and prep time than mild steel), how accessible the damaged area is, and whether the repair is a patch weld or a full build-up. What we quote is what you pay, with no shop-rate surprises added once the welder is on-site.
Heavy Equipment Welding: On-Site vs. Shop Repair
Shop repair means loading the machine onto a trailer, waiting for a bay, and paying for the downtime in between. On-site repair is faster, less expensive, and puts the machine back into service the same day. CanaWelding brings a fully equipped mobile welding unit, generator, and CWB-certified welder directly to the job site, so there's no transport, no waiting list, and no second trip because a piece of equipment got left at the shop.
How It Works: Assess, Quote, Weld
Assess
A certified welder inspects the damage on-site or from photos, confirms the steel grade, and identifies whether the job needs a patch weld, a build-up weld, or both.
Quote
A clear, itemized quote before any work starts. What we quote is what you pay.
Weld
CWB-certified repair performed on-site with documentation provided, so the equipment is back to work the same day.
Backed by a Structural Framing Background
CanaWelding is the welding division of CanaStruct Inc., owned by Zura Mirzikashvili, a Licensed HCRA Builder & Vendor with a construction and structural framing background dating to 2011. Heavy equipment welding carries the same load-bearing stakes as structural steel. A cracked boom arm or a failed frame weld is not a cosmetic fix, it is a structural one. That is the standard CanaWelding's welders are held to on every piece of equipment they touch.

Frequently Asked Questions
What types of heavy equipment do you weld?
CanaWelding repairs excavators, backhoes, bulldozers, graders, loaders, cranes, trailers, and conveyor systems. If a machine is built from structural or high-strength steel, a CWB-certified welder can assess and repair it on-site, without loading it onto a trailer first.
Are your welders CWB-certified?
Yes. Every welder CanaWelding sends to a job site is CWB-certified under CSA W47.1, the same standard engineers specify on structural drawings. It's not a self-declared credential, it's a regulated one, verified through the Canadian Welding Bureau.
How much does equipment welding repair cost?
Minor repairs on standard structural steel components typically range from $400 to $1,200 on-site. Equipment welding repair cost depends on the extent of the damage, the steel grade, access to the machine, and whether the job is a patch weld or a build-up weld. What we quote is what you pay, with no shop-rate surprises added after the welder arrives.
Can you weld high-strength steels like AR400 and Hardox?
Yes. CanaWelding's welders work regularly with AR400, AR500, Hardox, and T1-grade steels, using the correct preheat, filler metal, and process for each grade. Welding these steels without matching the process to the material can leave the joint weaker than the surrounding metal, so this isn't work handled with a standard mild-steel setup.
Do you provide weld documentation for regulated equipment?
Yes. CanaWelding provides weld documentation as required for regulated or fleet-managed equipment, including photos and a written record of the repair performed.
What are the two major types of weld repair?
The two major types of weld repair are patch welding and build-up welding. Patch welding cuts out a cracked, holed, or broken section of steel and welds a new patch or plate over the damage. Build-up welding deposits layers of weld metal onto a worn surface, like a bucket tooth or cutting edge, to restore the part's original dimensions instead of replacing it.
How much does patch welding cost?
It depends. Patch welding cost is driven by the size of the damage, the steel grade, and how accessible the area is on the machine, so every project is different. The only way to get an accurate number is a free, on-site quote, not a flat rate quoted over the phone.
Do you serve Mississauga and Brampton?
Yes. CanaWelding dispatches mobile welders for heavy equipment repair across Mississauga and Brampton, along with the rest of the GTA, usually with same-day availability.
Ready to Put Your Equipment Back to Work?
A cracked boom, a worn bucket, or a fractured frame doesn't need a shop appointment. CanaWelding sends a CWB-certified welder to the job site, assesses the damage, and gets equipment back to work the same day.
