Introduction: Why Quality Welding Matters for Your Vehicle
Imagine driving to meet your family on Eid morning, and your car fails its MOT because of a rusted sill. Or worse, a cracked alloy wheel gives way on a roundabout. These are not just inconveniences—they are safety hazards. At MJ Welding & Fabrication, we believe your vehicle should be as ready for celebration as you are. That is why we are offering 30% OFF all our welding and fabrication services this Eid-ul-Adha.
Whether you need car welding in Stourbridge, alloy wheel crack repair, or aluminium chassis fabrication, our 15+ years of expertise ensure your car, van, or camper van is restored to structural perfection. This guide will explain everything you need to know about modern automotive welding, why steel and aluminium require different techniques, and how our Eid offer makes professional repairs more affordable than ever.
Understanding Automotive Welding – MIG, TIG, and ARC
Not all welding is the same. A professional garage uses specific methods depending on the metal type, thickness, and location on the vehicle. At MJ Welding & Fabrication, we master three key techniques:
MIG Welding (Metal Inert Gas) – For Structural Strength
MIG welding is the workhorse of car body repairs. It uses a continuously fed wire electrode and shielding gas to create strong, fast welds. We use MIG welding for:
- Car sills and wheel arches – Common rust areas on vehicles over 5 years old.
- Chassis rails and subframes – Restoring the backbone of your car or van.
- Exhaust brackets and mounts – Stopping annoying rattles and misalignments.
Why MIG for MOT repairs? MOT testers look for corrosion within 30cm of structural mounts (seatbelts, suspension, etc.). MIG welding deposits strong, clean metal that passes inspection easily.
TIG Welding (Tungsten Inert Gas) – Precision for Aluminium & Stainless Steel
TIG welding is like surgery for metals. It uses a non-consumable tungsten electrode, giving the welder complete control over heat and filler material. This is essential for:
- Alloy wheel crack repair – Aluminium wheels require low heat input to prevent warping.
- Aluminium body panels – On Land Rovers, Audi, Jaguar, and modern vans.
- Stainless steel exhausts – Creating leak-proof, smooth joints.
Key Fact: Aluminium dissipates heat 5x faster than steel. Without TIG expertise, welds crack easily. Our technicians use pulsed TIG to preheat and cool gradually, ensuring a permanent repair.
ARC Welding (Stick Welding) – Heavy-Duty Structural Repairs
While less common on thin body panels, ARC welding is our choice for commercial vehicles, truck chassis, and thick mounting brackets. It penetrates deep into heavy steel, ideal for:
- Commercial van chassis extensions
- Tow bar mounting plates
- Agricultural vehicle repairs
The Most Common Welding Repairs (With Eid Discount)
Our 30% OFF Eid offer applies to every service below. Here is what each repair involves and why professional work matters.
1. Alloy Wheel Crack Repair (Most Popular Service)
The problem: Potholes, kerb impacts, and fatigue cracks in alloy wheels. Even a hairline crack causes slow air leaks and, under hard braking or cornering, sudden wheel failure.
Our process:
- Step 1 – Crack detection: We use dye penetrant testing to find the full crack length (often longer than visible).
- Step 2 – Grooving: V-ing out the crack to create a V-shaped groove for full penetration welding.
- Step 3 – TIG welding: Using AC (Alternating Current) TIG with 4043 or 5356 aluminium filler rod.
- Step 4 – Heat treatment: Stress-relieving the weld area to prevent future cracks.
- Step 5 – Machining & balancing: We skim the wheel face and re-balance to factory spec.
Why trust us? A backyard weld on an alloy wheel is dangerous. Porosity (tiny gas bubbles) weakens the joint. Our TIG process ensures 100% dense welds, restoring wheel strength to 90-95% of original.
Eid Offer Price: 30% off our standard £80-£150 per wheel.
2. MOT Failure Car Welding – Pass First Time
In the UK, corrosion is a leading cause of MOT failure, especially on vehicles over 10 years old. Common failure points:
- Nearside and offside sills (within 30cm of suspension or seatbelt mounts)
- Outer and inner sills
- Floor pans – Especially under driver/passenger feet
- Spring mounting points – Front and rear
- Subframe fixing points
Our MOT welding service:
We do not just patch over rust. We cut back to clean, weldable metal, fabricate new sections from zinc-coated steel, and weld using a stitch technique (to prevent distortion). Every weld is then sealed, primed, and undercoated.
Pro tip: Book your MOT welding with our Eid offer. Even if your test is 2 months away, repairing early prevents rust from spreading to expensive areas like chassis legs.
3. Aluminium Welding – Cars, Vans & Campers
Aluminium is lightweight and strong, but it is finicky to weld. Common issues we fix:
- Cracked aluminium sumps (oil pans)
- Aluminium chassis cracks – On trailers, horseboxes, and camper vans
- Aluminium body panels – Dents, tears, and seam splits
- Aluminium radiator brackets
Why aluminium fails: Aluminium forms an oxide layer that melts at 2000°C (vs 660°C for the base metal). Without AC TIG cleaning action, welds are contaminated. Our Lincoln Electric TIG welders automatically adjust frequency to break the oxide layer, creating clean, shiny welds.
4. Car Sills & Wheel Arches Welding – Structural Restoration
Sills are the structural beams under your doors. When they rust, your car’s rigidity drops by up to 40%. Our process:
- Remove interior trim and sound deadening (to prevent fires)
- Cut out all perforated metal
- Fabricate new sills from 1.2mm or 1.5mm Zintec steel
- Weld using plug welds (like factory spot welds) and continuous seams
- Apply weld-through primer inside cavities
- Finish with seam sealer and stone chip protection
For wheel arches: We replace the entire arch lip (where rust starts) and blend into the quarter panel, so you cannot see the repair.
5. Camper Van & Motorhome Welding
Campers face unique challenges: roof vents, window cutouts, and heavy interior fittings stress the body. We specialize in:
- Roof rack mount reinforcement
- Side step and running board brackets
- Pop-top roof frame repairs (aluminium and steel)
- Chassis extension for long wheelbase vans
Camper special: Use our EID30 code for 30% off any structural weld. We also offer free rust assessment for camper vans booked during the offer period.
Steel vs. Aluminium – Why Expertise Matters
Many garages claim to weld both, but the techniques are vastly different. Here is a simple comparison:
| Property | Steel | Aluminium |
|---|---|---|
| Melting point | ~1400°C | ~660°C |
| Heat conductivity | Low (holds heat) | High (dissipates heat fast) |
| Oxide layer | Minimal (rust, not oxide) | Thick, hard (melts at 2000°C) |
| Welding method | MIG or ARC most common | AC TIG or pulsed MIG required |
| Filler metal | ER70S-6 (mild steel) | 4043 or 5356 (aluminium-silicon) |
| Post-weld | Grind and paint | Stress relieve + polish |
Mistakes we see from non-specialists:
- Using steel wire on aluminium (guaranteed crack)
- No gas shielding (porous weld)
- Overheating aluminium (melted panel)
- Not cleaning oxide (dirty weld)
At MJ Welding & Fabrication, we have separate MIG torches, liners, and gas bottles for steel and aluminium to prevent cross-contamination.
Why Stourbridge Drivers Trust MJ Welding
Our location in Halesowen (just 10 minutes from Stourbridge town centre) makes us convenient for drivers across the West Midlands. But convenience is not why customers return. Here is what makes us different:

Frequently Asked Questions About Our Welding Services
Q1: Is welding as strong as the original metal?
A: When done correctly, yes. A proper MIG weld on clean steel is often stronger than the surrounding parent metal because the filler wire has slightly higher tensile strength. However, a heat-affected zone (HAZ) can be slightly softer. Our stitch welding technique minimizes HAZ, so strength remains OEM-like.
Q2: How long does a typical car sill welding take?
A: A single outer sill (one side) usually takes 2-3 hours for cutting, fabricating, welding, and sealing. Both sills take 4-5 hours. With our Eid discount, you save 30% on this labour.
Q3: Can you weld a cracked alloy wheel without removing the tyre?
A: No. For safety, we must remove the tyre and wheel weights. The heat from TIG welding (around 200°C at the rim) can damage tyre rubber and bead. We fully dismount, weld, then remount and balance.
Q4: Do I need to remove interior carpets for sill welding?
A: Ideally yes, or at least pull them back. Welding sparks can smolder behind carpets for hours before a fire starts. We ask customers to clear the boot and rear seat area. If you cannot, we use fire blankets and have an extinguisher ready, but removing carpets is safer.
Q5: What about rust prevention after welding?
A: We apply three layers inside and out: weld-through primer on bare metal, then brush-on seam sealer, then aerosol cavity wax (like Dinitrol or Bilt Hamber) injected into drain holes. This stops rust returning for years.
Q6: Do you weld stainless steel exhausts?
A: Yes, using DC TIG welding with 308L stainless filler rod. The result is a clean, golden weld that does not rust like mild steel exhausts. Plus, 30% off during Eid offer.
Q7: I have a Japanese import van (aluminium body). Can you help?
A: Absolutely. We regularly weld Toyota HiAce, Nissan Elgrand, and Mitsubishi Delica campers. Their aluminium panels are thin (1-1.2mm), so we use low-amp AC TIG with a copper backup bar to prevent blowthrough.
The Cost of NOT Welding – A Safety Perspective
Some drivers delay welding to save money. Let us look at the real costs:
- MOT failure: £40-£65 retest fee + the welding cost anyway.
- Crumbling sill: In a side impact, a rusty sill collapses. Repair cost? Your health or worse.
- Cracked alloy wheel: A full wheel blowout at 60mph could cause a multi-car accident. Insurance may not pay if a known crack was ignored.
- Exhaust leak near engine: Carbon monoxide entering cabin – headaches, dizziness, and for passengers (children/elderly), fatal.
Our Eid offer makes professional welding cheaper than a single MOT retest. At 30% off, a typical £200 sill repair becomes £140. That is less than a full tank of fuel.
Preparing Your Vehicle for Welding – A Checklist
To save time and ensure safety, please do this before your appointment:
- Remove all personal belongings from the boot and rear seats.
- Pull back carpets near the repair area (if possible).
- Remove any plastic trim clips (we can do this, but you avoid breakage risk).
- Ensure the fuel tank is less than half full (safety precaution).
- For alloy wheels: Leave the locking wheel nut key in the glovebox.
- Bring your MOT fail sheet if you have one (shows exact failure points).
If you cannot do any of the above, just tell us when booking. We will manage it, but preparation speeds up the job.
