Structural Welding Repairs Ireland
Load-bearing steel is not somewhere to cut corners. We weld chassis rails, mounts, crossmembers and structural sections back to strength using correct-gauge steel.
In short
- Structural welding covers the load-bearing steel of a vehicle: rails, outriggers, crossmembers, sills, mounts and subframe pick-up points.
- Repairs use steel of the correct gauge and profile, welded for full penetration, not thin plate tacked over rust.
- Every structural repair is sealed and coated so the new steel is protected from day one.
- Send WhatsApp photos of the affected area to 087 919 2193 and we'll tell you honestly whether it's a repair worth doing before you travel to the yard.
What counts as structural
Anything that carries load or holds a safety-critical component is structural: chassis rails and box sections, outriggers, crossmembers, suspension and subframe mounts, seatbelt anchorage areas, spring hangers and towing points.
These areas are also the ones an NCT tester examines most closely, because corrosion there changes how a vehicle behaves in a crash or under load.
How we approach a structural repair
- Assess and photograph the affected area on the ramp
- Support the structure before any steel is removed
- Cut back to clean, sound metal — no guessing
- Fabricate the replacement section to match the original profile
- MIG weld for full penetration, then dress the welds
- Seal, prime, paint and coat the finished repair
Why gauge and profile matter
Welding thin sheet over a rotten chassis rail is not a repair — it changes where load is carried and creates a stress point at the edge of the plate. Matching the original steel thickness and shape keeps the load path where the manufacturer intended it.
Where a section has an internal strengthener or a closed box profile, it has to be rebuilt the same way rather than left as an open channel.
Every repair, step by step
- Vehicle on the ramp — full underbody assessment and photos
- Corroded steel cut back to clean, solid metal
- Repair sections fabricated from correct-gauge steel
- MIG welded, dressed back and checked for full penetration
- Seams sealed to keep water out of the joint
- Primed and painted before any coating goes on
- Underbody protection applied over the finished repair
- Photos of the work sent to you before collection

Frequently asked questions
What is structural welding on a vehicle?
Welding repairs to load-bearing steel — chassis rails, outriggers, crossmembers, mounts, sills and suspension pick-up points — as opposed to cosmetic panel work.
Do you weld both chassis and body structure?
Yes. We work on ladder chassis, monocoque floor and sill structures, and the mounting points that connect suspension and body to them.
What welding process do you use?
MIG welding, which is the standard process for automotive steel repair of this kind.
Can you weld vehicles that failed the NCT on structure or corrosion?
Yes — that's a regular job. Send us the fail sheet and photos and we'll work to exactly what was marked.
Do you protect the repair afterwards?
Always. Bare welded steel corrodes quickly, so every repair is sealed, primed, painted and coated before it leaves.
