Alloy Wheel Welding: Everything You Need to Know
What is Alloy Wheel Welding?
Alloy wheel welding is a specialised repair process used to fix cracks and structural damage in alloy wheels. It involves fusing metal to restore the integrity of the wheel, preventing further deterioration. If left untreated, a damaged alloy wheel can lead to a flat tyre or even complete structural failure, making timely repairs essential.
Is it Safe to Weld Alloy Wheels?
Yes, welding alloy wheels is safe when done by a skilled professional. Many assume it compromises wheel integrity, but when executed correctly, it restores strength effectively. Ensuring the repair adheres to industry standards is essential for safety and longevity.
Cracked Alloy Wheel Repair
Cracks in alloy wheels typically result from potholes, kerbs, and rough road conditions. These cracks can weaken the wheel’s structure, potentially leading to failures if ignored. Severe impacts can also cause buckling, which further compromises performance and safety.
How to Identify a Cracked Alloy Wheel
- Gradual loss of tyre pressure
- Unusual vibrations while driving
- Visible cracks or deformations on the wheel’s surface
Does a Cracked Alloy Wheel Cause an MOT Failure?
Yes, a cracked alloy wheel can lead to an MOT failure if the tester deems the structural integrity compromised. Addressing damage promptly can help avoid this issue.
Will a Welded Alloy Wheel Fail an MOT Test?
A properly welded alloy wheel will not cause an MOT failure. However, if the repair is substandard, it may still fail. Professional execution is crucial to ensure roadworthiness.
Insurance Rejection
Many, but not all, insurance companies are hesitant to cover damage to repaired wheels, whether they've been welded or not. This is primarily due to the difficulty in assessing the long-term integrity of a repaired wheel after an accident. Even a professionally done weld can be a potential point of weakness, and insurers are concerned about liability if the wheel were to fail in a subsequent accident.
They prefer new wheels because they can be guaranteed to meet factory specifications. However, some insurers may cover welded wheels if the repair is documented and performed to specific industry standards (e.g., ISO 16949 or SAE J2530). It's crucial to check with your insurance provider before having any wheel repairs done. Ask them specifically about their policy regarding welded wheels and what documentation they require.
How Long Does It Take to Weld an Alloy Wheel?
The process can take anywhere from a few hours to a full day, depending on factors like the crack’s length and location, the wheel’s material (some alloys are more challenging to weld), and the type of finish required.
For example:
- A simple crack near the rim might only take a few hours.
- A complex crack near the hub requiring straightening could take a full day.
- Some materials, such as magnesium alloys, require extra care and preparation, potentially extending the repair time.
Different Welding Techniques for Alloy Wheels
- TIG (Tungsten Inert Gas) Welding: The most commonly used method for alloy wheels, TIG welding provides precise heat control, making it ideal for thin materials and delicate repairs.
- MIG (Metal Inert Gas) Welding: While faster than TIG welding, MIG welding is less precise and typically not recommended for high-performance alloy wheels.
- Pulsed TIG Welding: This advanced technique is used for heat-sensitive materials like magnesium alloys, allowing better temperature regulation.
How to Find a Qualified Welder
Look for welders certified by relevant organisations. Ask to see examples of their work, enquire about their experience, and check online reviews or referrals from reputable mechanics or tyre shops.
Alternatives to Welding
- Wheel Replacement: The safest option for severely damaged wheels.
- Professional Refurbishment: Suitable for cosmetic damage but does not address structural cracks.
However, refurbishment does not address structural cracks. If your wheel has any cracks, even small ones, they must be repaired before any cosmetic work is done.

Final Thoughts
Alloy wheel welding is a practical repair method when performed correctly. Regular maintenance and professional inspections ensure the longevity and safety of the repaired wheel. If you suspect a crack in your alloy wheel, seek expert advice to prevent further damage and maintain optimal road safety.
