Structural Welding & Fabrication — Edmonton Heavy Duty
A cracked crossmember shouldn't cost youa second vendor and a second week.
Structural welding, frame and fender repair, exhaust work, trailer attachments and one-off fabrication — done here, alongside the mechanical repair, not sublet out. Which is why a structural finding doesn't stall the rest of the job.
- 48 hrs
- Inspection results from scheduled booking — guaranteed
- 24 hrs
- Written estimate after diagnosis — parts & labour itemized
- 40,000 sq. ft.
- Edmonton facility — welding and mechanical under one roof
Proof of capability
Capability you can check before you commit
Welders on staff, not on call — so structural work happens in the same building and the same booking as the mechanical repair, and a crack found on Tuesday doesn't become another shop's Friday. 20-tonne overhead cranes and the floor space to hold a frame or a trailer while it is worked on. Authorized CVIP inspection station, so a structural finding at inspection becomes a repair and a re-inspection in one visit. Working out of a 40,000 sq. ft. Edmonton facility.
What Mach 6 handles
The problems you bring us
Structural Welding — Frames, Crossmembers & Mounts
“The inspection found a crack in the frame.”
Structural welding on frames, crossmembers and mounts. This is the repair that decides whether a unit goes back to work or gets written down, and it is the one where who did the weld matters as much as that it was done. The repair goes in the unit's file with the rest of the inspection paperwork.
Truck Frame & Fender Repair
“It's been rubbing and now it's torn.”
Frame and fender repair, including the corrosion damage that Alberta winters and road salt do to mounting points long before they do it to anything visible. Repaired properly rather than patched, because a fender mount that fails twice takes a wiring harness with it the second time.
Exhaust Welding & Manifold Repair
“It's blowing at the manifold and it stinks in the cab.”
Exhaust welding and repair, manifolds included. An exhaust leak is a cab-air problem, an emissions-reading problem and a heat problem all at once — and on an aftertreatment-equipped unit it can throw sensor faults that look like something far more expensive.
Trailer Attachment & Accessory Mounting
“I need the headache rack and the toolbox moved.”
Trailer attachment and accessory mounting — racks, boxes, plates, hitches and mounts, put on so they stay on. Attachment work done without regard for what the frame is doing underneath is how a mount becomes a crack two seasons later.
Custom Fabrication for Heavy Equipment
“Nobody makes the part anymore.”
Fabrication to suit the unit where an off-the-shelf part doesn't exist — brackets, mounts, guards, plates. Tell us the unit and what has to attach to it. On older equipment this is frequently the difference between a machine that works next season and a machine that becomes parts.
Welding Alongside Mechanical Repair — Not Sublet
“The last shop found the crack and sent me somewhere else.”
That's usually how it happens — a structural finding turns up mid-repair, and a shop without welders has to stop, quote a second vendor, and hand you a second schedule. Here it is one estimate, one booking, one record. This block is the reason the page exists.
The commitments in writing
Two promises. Both in writing.
The Downtime Promise
Inspection results within 48 hours of your scheduled booking — guaranteed. A comprehensive estimate within 24 hours of diagnostic completion. Worst case, that's 72 hours from drop-off to a number you can act on — and you'll hear from us before then, not after. Every unit leaves with a condition report and a digital vehicle inspection you can make decisions from. No surprises. No delays. Just results.
The Estimate Lock
Serial estimating — approve one number, then watch it grow — is one of the top three issues for fleets in this industry. Our Estimate Accuracy & Approval Policy ends it: once approved, your estimate is locked on price and scope. Changing a locked estimate takes manager approval — and nothing changes without yours.
How the process works
Four steps, same order, every time
Same sequence whether it's one unit or a fleet program — that's what makes the 48-hour and 24-hour commitments something we can actually hold.
Tell us what's cracked, or let us find it
Most welding jobs here start as a mechanical booking or an inspection. Tell us the unit and what you've seen; if it turns up during another repair, you'll hear about it the same day.
We assess before we quote
The crack gets looked at in context — what caused it, whether the surrounding structure is sound, and whether a repair or a section replacement is the right call. Photos of what we find, every time.
Your number, inside 24 hours
Parts, material and labour split out, and the structural work priced alongside the mechanical work rather than as a separate job. Approved means locked — changes take manager approval, and nothing changes without yours.
Back on the road, on the record
Repaired, and where the work calls for it re-inspected, with the structural repair documented in the unit's digital history. That record matters more here than almost anywhere else — it is what a buyer, an insurer or an inspector will ask about.
Every job leaves here with a record: what was inspected, what was found, what was approved and what was done. That record is what turns a repair into a maintenance history you can plan against.
FAQs
Questions fleets ask us
Do you fabricate custom mounts and brackets?
Yes. Tell us the unit and what has to attach to it.
Is welding available as part of a larger repair?
That's usually how it happens. Having it in-house is what keeps a structural finding from stalling the rest of the job.
Don't take the website's word for it
Ask to see the paper. A real condition report with the photos of what was found, and a locked estimate — before you commit the unit.
