Back on the road, safely
Aluminum Diesel Fuel Tank Repair in Calgary, Alberta
We understand that downtime costs money — that’s why we’re committed to getting your equipment back on the road or job site safely and efficiently. With years of experience in mobile welding, aluminum fabrication, and tank restoration, we deliver quality craftsmanship you can trust.
A leaking or cracked aluminum tank is usually repairable. Aluminum fuel tanks are welded from fairly thin sheet, so the repair has to be done cleanly and with careful heat control, otherwise the area around the weld can crack again. Getting the prep and the process right is what makes the fix last.
- Heavy trucks, semi-trailers and construction equipment
- Pickup tanks through large semi and equipment tanks
- In-shop repairs or mobile service
What we fix
Common Aluminum Fuel Tank Problems We Repair
A quick look at the most common tank failures we see.
Corrosion and pinhole leaks
Corroded spots and pinholes are cleaned back to sound metal and sealed with weld.
Impact or puncture damage
Dents, impact damage and punctures are repaired or patched.
Broken mounting brackets
Brackets and straps are re-welded or rebuilt so the tank sits securely.
Filler neck and cap repairs
Damaged filler necks and cap areas are repaired to seal properly again.
Drain plug and bung replacement
Worn drain plugs and bungs are replaced and welded in.
Our skilled welders inspect every tank thoroughly before repair to ensure structural integrity and safe operation.
How We Repair an Aluminum Fuel Tank
Thorough prep and testing for a safe, leak-free repair.
Inspect the Tank
We find every leak, crack and weak area and check the overall condition of the tank.
Prepare It Safely
The tank is emptied and cleaned so it is safe to weld, and the repair area is taken back to clean aluminum.
Weld the Repair
TIG or MIG welding is matched to the tank wall and the type of damage, with brackets and fittings rebuilt as needed.
Pressure-Test
Every repair is pressure-tested before the tank goes back on the truck or machine.
Repairs by type
Typical Tank Repairs
Select a tab to see how each problem is handled.
Cracked Seams and Split Welds
Vibration and frame flex put stress on tank seams and the welds around mounts. Once a crack starts it keeps growing, so we grind it out completely, weld it with full penetration and blend the area so the tank carries load evenly again.
Mounting Brackets and Straps
A tank that moves on its mounts will crack sooner or later. Broken or fatigued brackets are re-welded or replaced, and worn strap areas are reinforced so the tank stays put.
Filler Necks, Bungs and Drain Plugs
Leaks often start at filler necks, sender bungs and drain plugs. We repair or replace the fitting and weld it in so it seals properly. Read more in our fuel tank repair article.
