Alloy Wheel Repair & Welding — Valencia
Structural crack repair, TIG welding, wheel straightening, and cosmetic kerb damage restoration. Every repair starts with a safety-first structural assessment. The Wheel Lab, Alaquàs, Valencia.
Call Us Now WhatsApp for AssessmentDamaged alloy wheels are more than an aesthetic problem. A bent rim causes tyre bead seating issues, uneven wear, and vibration that gradually damages wheel bearings and steering components. A cracked wheel is a genuine safety risk — particularly at motorway speeds. At The Wheel Lab, we take structural integrity as seriously as cosmetic appearance, and every wheel that comes in for repair is assessed structurally before any aesthetic work begins.
Our repair workshop handles everything from the most common kerb scrapes to complex crack repairs requiring TIG welding and heat treatment. Whether you have bent a wheel on one of Valencia's many tram tracks or potholed roads, or arrived in Spain with a wheel damaged in transit, we can assess the situation and give you an honest recommendation — including telling you when a wheel is beyond safe repair.
Types of Alloy Wheel Damage We Repair
Kerb Damage
Scuffs, gouges, and material removal from the outer lip and spoke faces caused by contact with kerbs. The most common damage type. Repaired cosmetically after structural check.
Bent Rims
Impact deformation to the rim, typically from potholes. Causes air loss and vibration. Straightened using hydraulic press equipment with dial gauge verification.
Cracks & Fractures
Stress fractures typically at spoke roots or barrel. Repaired using TIG welding with aluminium filler rod, followed by post-weld heat treatment and finishing.
Corrosion Damage
Deep oxidation pitting, typically on the barrel or bead seat area. Treated, filled where appropriate, and re-coated to restore corrosion resistance.
Impact Damage
High-energy impacts from potholes or road debris that deform spokes or the face. Assessed case by case — some impacts cause non-visible internal cracking.
Valve Hole Issues
Damaged or corroded valve holes causing slow air loss. Cleaned, assessed, and restored or sleeved as appropriate.
TIG Welding for Alloy Wheels
Tungsten Inert Gas (TIG) welding is the correct process for structural repair of aluminium alloy wheels. It provides precise, controllable heat input and produces clean, strong welds that are suitable for finishing — unlike MIG welding, which is faster but leaves a coarser bead that is difficult to dress to a smooth surface.
Our TIG welding operators work specifically with aluminium alloys. The process requires:
- Thorough cleaning of the crack or fracture area to remove all contamination
- Correct filler rod selection matched to the wheel's aluminium alloy grade
- Controlled pre-heat to reduce thermal shock and prevent new cracking
- Post-weld heat treatment to relieve internal stresses in the repaired zone
- Dressing and finishing of the weld bead to match the surrounding surface
A correctly executed TIG weld repair on an alloy wheel restores structural integrity to a level suitable for normal road use. We will always document what was found and what was done, so you have a clear record.
Wheel Straightening
A bent alloy wheel — one where the rim has been deformed out of its original flat plane by a pothole or other impact — can often be straightened using a hydraulic press and a suitable forming die. The process involves careful cold or warm pressing of the deformed section back to within manufacturer tolerances.
Straightening is verified using a dial gauge to measure runout both radially and laterally. We do not consider a wheel "straight" until it measures within acceptable tolerances — typically 0.5–1.0 mm runout for road use.
Our Safety-First Assessment Protocol
Before any repair work commences, every wheel at The Wheel Lab goes through a structured assessment:
- Visual inspection of spoke roots, barrel, bead seats, and valve hole area
- Measurement of remaining material thickness where damage is present
- Rim runout measurement to identify bending and distortion
- Assessment of whether the damage type and location is safely repairable
- Honest recommendation — we will tell you clearly if a wheel should be replaced rather than repaired
We do not charge for this assessment, and we do not have a financial incentive to pass wheels that should fail — our reputation depends on the safety of our work.
Repair Workflow
From intake to collection — what happens to your wheel.
Structural Assessment
Visual and dimensional inspection before any work. Safety clearance before proceeding.
Quote & Approval
Fixed written quote provided. No work begins until you approve the price.
Strip & Clean
All coatings removed to allow accurate assessment of damage extent on bare metal.
Structural Repair
Welding, straightening, or crack repair as required. Post-repair inspection confirms integrity.
Cosmetic Finish
Restored to original or customer-specified finish: robotic painting, paint, or polishing.
Final QC
Runout recheck on straightened wheels. Visual inspection before collection.
Repair and Refinish Combination
In most cases, structural or cosmetic repair is combined with a full wheel refinish. Once a wheel has been stripped and repaired, it makes both practical and economic sense to refinish it to a high standard at the same time. We can finish repaired wheels in:
- Original factory colour (robotically painted to match)
- Custom colour of your choice from our 200+ colour library
- Diamond cut finish (if the wheel design is suitable)
- Polished or mirror finish

What our customers say
Real reviews from our customers, translated from Spanish.
“I brought in the wheels of my BMW 3 Series with deep kerb scratches. The Diamond Cut CNC left them looking like they had just come out of the factory. The precision of the machine is incredible — every line is perfect.”
“They repaired a wheel on my Golf R that had a hard impact and I thought was scrap. They straightened it, repainted it and it came out perfect. They saved me buying a new €400 wheel.”
“Diamond Cut on my MINI Cooper wheels. They looked destroyed by the Valencia kerbs and now they shine like new. The CNC lathe works magic. Fair price and fast turnaround.”
“Robotic painting for my Mercedes C-Class wheels. The finish is flawless — no orange peel, no imperfections. This is not a workshop, it is a real laboratory. I will definitely be back.”
“All four wheels on my Audi A4 had severe corrosion. They returned them with an OEM finish, like new. You can see the 5-phase protocol they follow in the final result. Very professional.”
