Our Emergency TIG Welding Protocol
A structural weld requires precision, not just heat. Here is the step-by-step process we follow for every cracked alloy wheel.
Inspect & Assess
We remove the tyre and run a dye penetrant test to identify the crack path, depth, and termination point. We measure length and location.
Stop-Drill & Prep
We drill a relief hole at the crack termination point and grind a deep V-groove along the fracture to expose clean, unoxidised aluminium.
TIG Weld
Using AC/DC TIG equipment, we lay structural passes from both inside and outside the barrel using matching aluminium-magnesium filler rods.
Test & Finish
We grind the weld flush, pressure-test at full PSI, balance the wheel, and ensure the bead seats flawlessly.
Common Alloy Wheel Cracks We Weld
Every cracked wheel is different. Here are the most common damage patterns we see across Stockport.
Pothole Impact Crack
Inner barrel cracks caused by hitting a pothole at speed. The impact stress fractures the aluminium — often invisible until the tyre deflates. We weld these structural cracks safely.
Hairline Crack Slow Puncture
Your tyre keeps losing pressure but there is no nail. This is a classic hairline crack on the inner barrel. Air escapes through the fracture under load. We weld and seal it completely.
Cracked Rim Lip
Kerb strikes or severe impact can split the rim lip. This affects the tyre bead seal and causes vibration. We weld the lip and machine it back to spec.
Severe Structural Crack
Longer cracks (over 2 inches) or multiple fractures in the barrel. Requires multi-pass welding and careful heat management to restore full strength.
Previous Poor Repair
Someone previously attempted a MIG weld or epoxy patch that failed. We grind out the bad repair, prep the metal properly, and weld it to structural standard.
⚠️ What We Cannot Weld
We do not weld spokes, the central hub mounting face, or wheels with multiple fractures in high-stress zones. We will tell you honestly if the wheel is scrap.
Who We Help With Emergency Wheel Welding
Cracked alloy wheels affect all kinds of drivers — from daily commuters to performance car owners.
Stranded Motorists
Flat tyre caused by a crack you cannot see. No spare wheel or the spare is a space-saver. We weld the crack and refit your tyre the same day so you can drive safely.
High-Performance Cars
Low-profile tyres on sports cars transmit huge impact forces. Cracks are common on 18″–22″ rims. We repair expensive OEM wheels without replacing them.
Commercial Vans & 4x4s
Heavy vehicles crack wheels under load, especially on poorly maintained roads. We weld commercial wheels and pressure test to high PSI ratings.
Enthusiasts & Classic Cars
Aftermarket or rare wheels that cannot be replaced easily. We weld them to structural spec and can arrange cosmetic refinishing after the repair.
Areas We Cover For Alloy Wheel Welding
Workshop-based in Stockport — serving all surrounding areas.
Emergency Alloy Wheel Welding — Safe, Structural, Same-Day
Alloy wheels are made from cast aluminium alloys that are strong but brittle under impact. When you hit a pothole, kerb, or debris at speed, the sudden force can fracture the metal. The result is a crack — often invisible from the outside but weeping air through the inner barrel. A cracked wheel is dangerous because the fracture can propagate and the wheel can fail catastrophically. But a professional TIG weld, executed correctly, restores structural integrity and saves you the cost of a new wheel.
Simply slapping epoxy or MIG welding over a crack is not a repair — it is a temporary patch that will fail under tyre pressure and heat cycling. Structural welding requires AC/DC TIG equipment, matching filler material, and a precise workflow that includes crack assessment, stop-drilling, and multi-pass welding.
TIG Welding vs MIG Welding — Why It Matters
MIG welding applies too much heat too quickly, creating a brittle, porous weld that does not fuse properly to the parent aluminium. The heat-affected zone becomes weak and prone to cracking again within weeks. TIG welding (Tungsten Inert Gas) uses a tungsten electrode to generate precise, controlled heat. The welder can adjust amperage in real time, ensuring deep penetration without overheating the surrounding metal. For alloy wheels, AC (Alternating Current) TIG welding is essential to break through the aluminium oxide layer. We use AC/DC TIG at 150+ Amps with 1.5mm–2mm aluminium-magnesium filler rods that match OEM tensile strengths — creating a weld joint that is often stronger than the original cast wheel.
What Cracks Can Be Safely Welded?
Safe to weld: Inner rim barrel cracks (the most common), rim lip cracks, and some face cracks that are not on structural load-bearing sections. Cracks under 2 inches in length are generally straightforward. Longer cracks require multi-pass welding but are still repairable if the wheel is not extensively fatigued.
Not safe to weld: Spoke cracks, central hub mounting face cracks, multiple cracks on the same wheel, and any crack that runs through a high-stress structural point. In these cases, the wheel is structurally compromised and cannot be restored to a safe condition. We will tell you honestly if replacement is the only option — safety always comes first.
The Step-by-Step Structural Weld Process
A structural weld is not a single action — it is a sequence of precise steps. First, we remove the tyre and perform a dye penetrant test to map the crack. This reveals the exact length and direction of the fracture, including invisible micro-fractures. Second, we stop-drill the crack termination point — a relief hole that prevents the crack from propagating under thermal stress during welding. Third, we grind a deep V-groove along the crack line, removing all paint, lacquer, and oxide to expose clean aluminium. Fourth, we pre-heat the surrounding zone to prevent the alloy from acting as a massive heat sink. Fifth, we perform AC/DC TIG welding from both the inside and outside of the barrel, laying down structural passes with matching filler material. Finally, we grind the weld flush, pressure test at full PSI, and balance the wheel.
Cost Comparison — Weld vs New Wheel
A new OEM alloy wheel for most cars costs £300–£600. For premium brands (BMW, Mercedes, Audi, Porsche), a single wheel can cost £800–£1,200 or more. Aftermarket replicas may be cheaper but often have different offset and load ratings. Our welding service starts from £50 for a small crack — a fraction of the cost. You retain your original wheels, maintain your vehicle’s value, and get back on the road the same day. For wheels with multiple cracks or severe damage, we assess on a case-by-case basis and provide a transparent quote before any work begins.
After Welding — Cosmetic Refinishing Options
Welding generates localised heat that discolours or scorches the surrounding finish. If the crack is on the inner barrel, this is invisible once the tyre is fitted. If the crack extends to the outer face, we recommend a full cosmetic refurbishment after welding. We offer powder coating and diamond-cut refinishing services that restore the wheel to factory condition. Many customers opt for a full set refurbishment to ensure all wheels match perfectly.
Frequently Asked Questions — Alloy Wheel Welding Stockport
Everything you need to know about emergency alloy wheel welding, safety, and costs.
Is it safe to drive on a welded alloy wheel?
Yes, provided the weld is an AC/DC TIG repair executed with proper deep penetration and stop-drilling on the inner barrel or rim lip. It is completely unsafe to weld structural components like spokes or the central mounting hub.
How long does an emergency alloy wheel weld take?
A structural emergency crack repair typically takes 1 to 2 hours. This includes stripping the tyre, preparing the metal, precision welding, and immersion pressure testing.
Why is my tyre losing air pressure if there is no nail in it?
This is a classic symptom of a hairline crack on the inner barrel of your alloy wheel, usually caused by hitting a pothole. Air forces its way through the fracture under the weight of the vehicle, causing a continuous slow puncture.
Will welding ruin the look of my custom wheels?
Welding requires intense local heat, which will naturally discolour or scorch nearby paint or powder coating. If the repair is on the inner rear barrel, it is invisible from the outside. If the crack extends to the front face, a cosmetic diamond-cut or powder coating refurbishment is recommended after structural welding.
What types of cracks can be welded on an alloy wheel?
We can weld cracks on the inner rim barrel, the rim lip, and the wheel face (depending on location). We cannot safely weld cracks on the spokes, the central hub mounting face, or any structural load-bearing component that compromises the wheel’s integrity.
How much does emergency alloy wheel welding cost in Stockport?
Hairline cracks under 1 inch start from £50. Deeper cracks (1–2 inches) on the inner barrel cost from £80. Complex or multi-pass structural repairs cost from £120. Send a photo on WhatsApp for an accurate quote before we start.
Can a cracked alloy wheel be welded without removing the tyre?
No. The tyre must be completely removed to inspect the crack properly, stop-drill the termination point, and perform the TIG weld safely. Welding with the tyre on is dangerous and prevents proper structural penetration.
What is the difference between TIG welding and MIG welding for alloy wheels?
TIG (Tungsten Inert Gas) welding is the only safe method for structural alloy wheel repairs. It provides precise heat control and allows the use of matching aluminium-magnesium filler rods for deep fusion. MIG welding applies excessive heat and results in brittle, porous welds that fail under pressure.
How do I know if my alloy wheel crack is repairable?
A wheel is repairable if the crack is confined to the inner rim barrel or lip and is under 2 inches in length. We assess the location, direction, and depth using dye penetrant testing. Cracks on spokes, the hub, or multiple fractures in the same area are generally not safe to weld.
Is a welded alloy wheel as strong as a new wheel?
When performed with correct AC/DC TIG technique, stop-drilling, and deep V-groove preparation, a welded repair can restore the wheel to its original structural integrity — often exceeding the parent metal’s strength at the weld joint. However, the surrounding heat-affected zone must be carefully managed to prevent micro-fractures.
Do you offer mobile alloy wheel welding in Stockport?
We offer a mobile service for initial inspection and tyre removal. However, TIG welding requires a controlled workshop environment with specialised AC/DC equipment and a welding bench. We can collect your wheel or you can bring the vehicle to our Stockport workshop for the repair.
What causes alloy wheels to crack?
The most common cause is impact with potholes, kerbs, or debris at speed. Low-profile tyres transmit the shock directly to the wheel rim. Other causes include manufacturing defects, over-tightening of wheel nuts, and long-term metal fatigue from cyclic loading.
Can you weld a cracked alloy wheel on the inside barrel?
Yes. Inner barrel cracks are the most common and the safest to weld because they are not visible and the structural load is well-distributed. We have full access to the inner barrel once the tyre is removed and the wheel is mounted on our welding bench.
What is stop-drilling in wheel welding?
Stop-drilling is a technique where we drill a small relief hole precisely at the end of the crack. This prevents the crack from propagating further during the welding process due to thermal expansion. It is a critical step for ensuring the repair lasts.
Do you pressure test alloy wheels after welding?
Yes. Every welded wheel undergoes a full pressure test at operational PSI (typically 30–35 PSI for cars, higher for vans). We also perform a balance check and bead-sealing test before the wheel is returned to you.
Is it cheaper to weld or replace a cracked alloy wheel?
Welding is significantly cheaper. A replacement OEM alloy wheel can cost £300–£1,000+ depending on the make and model. Our welding service starts from £50 for a simple crack, saving you hundreds of pounds while retaining your original wheels.
Can you weld diamond-cut or polished alloy wheels?
Yes, but the diamond-cut or polished finish will be affected by the heat-affected zone around the weld. After structural welding, we recommend a professional diamond-cut or powder coating refurbishment to restore the cosmetic appearance.
How long does a welded alloy wheel repair last?
A properly executed TIG weld with correct preparation and matching filler material lasts the lifetime of the wheel. The welded area should not fail if the repair was performed to structural standards and the wheel is not subjected to repeated severe impacts in the same area.
Can you weld alloy wheels with cracks longer than 2 inches?
We assess each crack individually. Cracks longer than 2 inches require multi-pass welding and careful heat management. In some cases, we may advise that the wheel is beyond safe repair if the crack is extensive or located in a high-stress area.
What is the typical turnaround time for emergency wheel welding in Stockport?
For emergency bookings, we aim for a 1–2 hour turnaround. We prioritise urgent repairs so you can get back on the road the same day. Contact us with your location and crack details, and we’ll book you into the next available slot.
