Why Aluminium Welding Matters
Modern vehicles are evolving rapidly. Manufacturers are shifting from traditional steel to aluminium to reduce weight, improve fuel efficiency, and enhance performance. Aluminium is now found in chassis frames, body panels, engine components, and wheels. According to industry data, aluminium usage in vehicles has increased by over 80% in the last decade as automakers strive to meet stricter emissions regulations.
This shift presents a significant challenge for automotive repair. Welding aluminium is fundamentally different from welding steel. It requires specialist equipment, advanced techniques, and expert knowledge to achieve safe, durable repairs. At MJ Welding and Fabrication, we specialise in professional aluminium welding for cars, vans, and campervans across the West Midlands.

What Makes Aluminium Welding Different?
The Challenges of Aluminium
Aluminium behaves differently from steel under heat. It has a lower melting point (around 660°C compared to steel’s 1,370°C), but it also conducts heat much faster. This means heat spreads quickly away from the weld area, requiring higher amperage and faster welding speeds to achieve proper fusion.
Key challenges include:
- Oxide layer: Aluminium forms a tough oxide coating that melts at a much higher temperature (over 2,000°C) than the base metal. This oxide must be removed before welding, or it will contaminate the weld.
- Porosity: Aluminium absorbs hydrogen from moisture, which can cause bubbles (porosity) in the weld, weakening the joint.
- Cracking: Aluminium expands and contracts significantly under heat. Without proper technique, welds can crack as they cool.
Why TIG Welding Is the Gold Standard
TIG (Tungsten Inert Gas) welding is the preferred method for aluminium due to its precision and control. Unlike MIG welding, TIG allows the welder to separately control heat and filler material, making it ideal for thin sections and complex shapes.
TIG Welding – Best for aluminium panels, alloy wheels, stainless steel exhausts. Clean, precise, and spatter-free.
Why West Midlands Cars Need Expert Aluminium Welding
The Corrosion Challenge
While aluminium is more corrosion-resistant than steel, it’s not immune. The West Midlands’ combination of road salt, clay soil, and industrial air particulates creates an aggressive environment that can pit and corrode aluminium components. Salt spray acts as an electrolyte, accelerating galvanic corrosion when aluminium contacts steel.
Common Aluminium Components in Modern Vehicles
- Chassis frames – High-strength aluminium alloys are used in many premium and electric vehicles
- Body panels – Bonnets, doors, wings, and boot lids
- Alloy wheels – Aluminium alloys are standard for modern wheels
- Engine components – Cylinder heads, engine blocks, and sumps
- Suspension components – Control arms and subframes
Damage Typical in Aluminium Vehicle Parts
- Cracked or broken body panels
- Damaged aluminium structural components
- Corroded metal frames or subframes
- Weakened joints and seams
- Cracked alloy wheels
- Damage from potholes or impacts

Common Aluminium Welding Issues – Problems and Solutions
Issue 1: Cracked Aluminium Body Panels
The Problem: Aluminium body panels are prone to cracking from impact or metal fatigue.
The Solution: Precision TIG welding restores strength without warping the panel. We thoroughly inspect the damage, prepare the area by removing corrosion and aligning the metal, then apply TIG welding with carefully controlled heat. After welding, the panel is finished and inspected for structural integrity.
Cost and Time: Most aluminium panel repairs are completed within a few hours to a day, depending on the size and extent of the damage.
Issue 2: Damaged Aluminium Chassis Components
The Problem: A damaged chassis can compromise the safety and stability of your vehicle.
The Solution: We carefully inspect the aluminium chassis, repair cracks, or replace damaged sections using precision welding and structural reinforcement techniques. This process restores the vehicle’s strength, alignment, and overall driving safety.
Cost and Time: Complex chassis repairs may take 1-2 days.

Issue 3: Cracked Alloy Wheels
The Problem: Cracked alloy wheels are dangerous – they can lose air pressure suddenly or fail while driving. Common causes include potholes, kerb impact, corrosion, and overload.
The Solution: We use precision TIG welding to repair cracks and restore structural integrity. The crack area is ground clean, welded with matching aluminium filler rod, machined smooth, and pressure-tested.
Cost and Time: £60-120 per wheel – takes 2-3 hours.
Issue 4: Corroded Aluminium Panels
The Problem: Corroded aluminium panel edges and surfaces can compromise structural integrity and aesthetics.
The Solution: Corroded sections are treated and repaired using targeted welding techniques that remove damaged material and restore solid, clean metal. This prevents further corrosion from spreading.
Cost and Time: Varies by extent – typically 2-4 hours.

10 Frequently Asked Questions About Aluminium Welding
Q1: Is aluminium welding different from steel welding?
Yes. Aluminium requires TIG welding due to its heat sensitivity, while steel is commonly welded using MIG or ARC welding. Each method requires different equipment and skills to ensure a strong and durable repair.
Q2: Can you weld aluminium on my car?
Yes. We specialise in TIG welding for aluminium chassis, body panels, and alloy wheels. Our technicians are fully trained and equipped to handle all types of aluminium damage.
Q3: Does welding restore the original strength of aluminium?
Yes, when carried out by a professional using the correct method, welding restores the original strength and durability of the metal component, ensuring it performs reliably under everyday driving conditions.
Q4: How do I know if my aluminium panel needs welding or replacement?
Signs include visible cracks, corrosion, damaged body panels, unusual vehicle handling, or structural weakness after an accident. We recommend a professional inspection to assess the damage.
Q5: How long does aluminium welding take?
Repair time depends on the extent of the damage. Minor welding jobs can be completed within a few hours, while more complex structural repairs may require a longer assessment and repair period.
Q6: Is aluminium welding expensive?
It can be slightly more due to the specialist equipment and expertise required, but it is often still more cost-effective than a full panel replacement and delivers excellent results when done correctly.
Q7: Can you weld aluminium and steel in the same repair job?
Yes. Modern vehicles often use both materials, and our technicians are equipped and trained to handle both aluminium and steel welding in a single repair job with the correct technique for each metal.
Q8: Do you provide a warranty on aluminium welding repairs?
Yes. Every repair comes with a warranty on both parts and labour (3-12 months, depending on the part). We stand behind our work.
