Step-by-Step Alloy Wheel Crack Repair Process

Step-by-Step Alloy Wheel Crack Repair Process – What Happens at Onyx Alloys

Step-by-Step Repair Process

Step 1

Initial Inspection & Crack Assessment

Our technicians begin by thoroughly inspecting the wheel for visible cracks, hairline fractures, or hidden damage. We assess the severity, location, and repairability of the crack to determine if welding is a safe and viable option.

Step 2

Tyre Removal & Wheel Preparation

Once approved for repair, the tyre is safely removed, and the wheel is cleaned to remove any dirt, brake dust, or contaminants. This ensures the crack is clearly visible and ready for precise repair.

Step 3

Crack Grinding & Cleaning

The cracked area is ground back to bare metal to expose the full extent of the damage. This step is essential to ensure a strong bond and remove any corrosion or weak material from the weld zone.

Step 4

Precision TIG Welding

Using TIG (Tungsten Inert Gas) welding, we carefully repair the crack by applying new alloy material. This method delivers a high-strength, clean weld that restores the wheel’s structural integrity.

Step 5

Grinding, Shaping & Finishing

After welding, the repaired area is smoothed and shaped to match the original wheel profile. Our technicians ensure a seamless finish that’s both strong and visually tidy.

Step 6

Pressure Testing & Final Checks

Finally, the wheel is pressure tested to confirm the repair holds under load. Once cleared, the tyre is refitted, and the wheel is balanced – ready to go back on your vehicle.

Frequently Asked Questions

Is your welding process safe for all alloy wheels?

Yes – we use TIG welding, which is suitable for most aluminium alloy wheels and provides a strong, long-lasting repair.

Will the crack still be visible after repair?

No – the weld is smoothed and refinished to match the rest of the wheel. In most cases, it’s barely noticeable.

How long does the alloy wheel refurbishment process take?
Upto 3 working days depending on damage and service required.
Do you pressure test every repaired wheel?

Absolutely. Pressure testing is a crucial final step to ensure the integrity of the weld and safety on the road.

Can you repair multiple cracks on the same wheel?

We can often repair more than one crack, but this depends on the location and severity. We’ll advise honestly during inspection.

Do I need an appointment, or can I walk in?

Appointments are preferred, but we do accept walk-ins when possible. Give us a call to check availability.
