A dented panel, a rusted arch, or a crumpled section after a minor knock — bodywork damage is one of the most visible problems a vehicle can have, and also one of the most commonly underestimated by drivers. What looks like a simple dent can sometimes hide corrosion underneath, and what looks like a small rust patch can sometimes extend much further than the surface suggests. Getting it properly assessed by someone who welds and fabricates bodywork for a living, rather than just filling and painting over it, makes a real difference to how long the finished repair actually lasts.
At MJ Welding & Fabrication, we provide car bodywork welding and fabrication services to drivers across the West Midlands, from our Halesowen workshop out to towns and cities across the region. In this guide, we’ll explain what proper bodywork welding and fabrication involves, the services we offer nearby, the problems we solve most often, and how to find us wherever you’re searching from.
Why Bodywork Damage Needs More Than Filler
Cosmetic filler has its place for very minor imperfections, but it isn’t a genuine substitute for welding when metal has corroded through, cracked, or been structurally compromised. Filler sits on top of the problem rather than fixing it — if the metal underneath is still actively corroding, it will eventually show through again, often in a worse state than before it was first covered up.
Our guide on how to tell if your car’s sills are rusted explains how corrosion often spreads well beyond what’s visible on the surface, and our overview of the 5 most common car welding repairs covers just how often bodywork issues turn out to need genuine welding rather than a cosmetic fix.
Our Car Bodywork Welding & Fabrication Services
Body Panel Repair
Our body panel repair service handles dents, corrosion, and damaged sections, restoring the panel’s shape and structural integrity rather than just covering the problem with filler and paint.
Full Panel Replacement
Where damage is too extensive to repair economically, our car body panel replacement service fits a replacement panel correctly, matching it to the surrounding bodywork as closely as possible.
Sills & Wheel Arch Welding
Sills and wheel arches are two of the most common bodywork areas to corrode, and also two of the most common MOT failure points on vehicles of any age. Our sills and arch welding service and our guide on sill patch repair vs full replacement explain how we approach this work.
Structural Bodywork & Chassis Welding
Where bodywork damage extends into structural areas, our structural welding service and chassis repair service restore strength to DVSA-compliant standards, covered in more depth in our guide to professional structural welding for anyone wanting the full detail.
Aluminium & Steel Bodywork
Modern vehicles increasingly use aluminium body panels alongside steel structural sections underneath. Our aluminium and steel welding service and our guide on aluminium vs steel welding explain why bodywork repairs need to account for whichever material is actually involved on the vehicle in front of us.
MIG & TIG Welding
Our MIG welding service handles strong steel bodywork repairs, while our TIG welding service provides the precision needed for aluminium panels and detailed bodywork sections that need a cleaner finish. Our comparison guide on TIG vs MIG welding for cars explains the difference.
Exhaust Welding
Bodywork problems sometimes extend to the underbody as well as the visible panels. Our exhaust welding service handles splits, holes, and corrosion along the exhaust line.
Alloy Wheel & Rim Repair
Bodywork damage is often accompanied by wheel damage after the same incident, whether that’s a kerb strike or a more significant collision. Our alloy wheel repair service, alloy wheel crack repair service, and alloy rim crack repair service restore wheels alongside bodywork repairs where needed.
Camper Van & General Automobile Bodywork
Camper vans and larger vehicles often have extensive bodywork and cladding to maintain over their lifetime. Our camper van welding service and general automobile welding service cover this work across all vehicle types.
Classic Car Bodywork Restoration
Restoring bodywork on a classic vehicle often means fabricating replacement panels that are no longer available to buy anywhere. Our guide to classic car restoration welding explains what this specialist fabrication work typically involves.
On-Site Bodywork Welding & Fabrication
Not every bodywork job can come to a workshop, especially for larger vehicles or commercial fleets. Our on-site welding and fabrication service brings the right equipment directly to your location, and our subcontractor welding services support trade and commercial clients needing reliable bodywork welding capability.
Common Bodywork Problems We Solve Nearby
- Rusted or rotten sills and wheel arches, explained in why your car failed its MOT on corrosion
- Dented or crumpled body panels from minor collisions and everyday parking scrapes
- Corroded bodywork that’s spread beyond what looked like a small, contained patch
- Previous poor-quality filler repairs that have masked ongoing corrosion underneath the surface
- Discontinued bodywork panels on classic or older vehicles requiring genuine fabrication
- Mixed-material bodywork, where steel and aluminium panels meet and need different repair techniques
If you’re unsure whether your vehicle’s bodywork needs professional attention, our guides on 10 hidden signs your car needs welding and 7 signs of structural welding repair are useful starting points, and our MOT welding repairs explained guide covers what MOT testers are actually checking for on bodywork.
Why Bodywork Standards Matter for Your MOT
Bodywork corrosion in the wrong place isn’t just cosmetic — the official MOT inspection manual on structural integrity and corrosion sets out clear requirements for corrosion near structural and prescribed areas, meaning bodywork issues close to seatbelt mounts, suspension points, or steering components can cause an MOT failure even if the damage looks purely cosmetic at first glance. Our pre-MOT structural rust checklist is a useful place to start if a test is approaching and you want to catch anything early.
What to Look For in a Nearby Bodywork Specialist
Bodywork repair is one of those jobs where a poor result can be temporarily hidden under fresh paint, so it’s worth checking a few things before booking anyone nearby:
Do they explain whether the repair is filler or welding?
A trustworthy specialist should be upfront about which approach is being used, and why, rather than defaulting to filler for anything that can be visually disguised in the short term.
Can they identify the material involved?
Steel and aluminium bodywork need genuinely different repair approaches, so a specialist should confirm which one they’re working with before giving any quote.
Do they check beyond the visible damage?
Corrosion and structural issues often extend further than what’s immediately obvious on the surface, so a proper assessment should look beyond just the dented or discoloured area itself.
Do they offer fabrication as well as repair?
For discontinued panels or extensive damage, being able to fabricate a replacement section from scratch matters far more than simply patching what’s already there.
Do they mention MOT implications where relevant?
Bodywork near structural or prescribed areas can affect MOT compliance, so a specialist should flag this clearly rather than treating every repair as purely cosmetic by default.
This is exactly the standard we apply to every bodywork job at MJ Welding & Fabrication, and it’s a reasonable, practical checklist to use with any specialist you’re considering nearby, not only us.
What to Expect From a Bodywork Welding Appointment
1. A proper assessment. We check the full extent of the damage or corrosion, not just what’s immediately visible, since bodywork problems often extend further underneath the surface than they first appear.
2. A clear, honest quote. We explain the scope of the repair and the reasoning behind it, with a straightforward price and no hidden extras added once the job is already underway.
3. Correct preparation. Damaged or corroded metal is cut back to sound material before any welding begins — patching over a weak area just delays the same problem for a few more months.
4. The right process for the material. MIG for steel bodywork, TIG for aluminium panels, matched carefully to whichever metal is actually involved on that particular vehicle.
5. Finishing and protection. Repairs are smoothed, treated, and finished to blend in with the surrounding bodywork and protect against future corrosion.
6. A result built to last, and where relevant, built to satisfy DVSA structural requirements for years to come.

Frequently Asked Questions
How do I know if my bodywork damage needs welding rather than just filler? If metal has corroded through, cracked, or been structurally deformed, filler alone won’t fix it — it will only mask the problem temporarily, and the underlying issue will usually resurface later, often looking worse than before. A proper assessment can confirm whether welding is genuinely needed.
Can you match a replacement panel to my car’s existing bodywork? Yes, our full panel replacement service fits replacement panels correctly to match the surrounding bodywork as closely as possible, both in terms of fit and finish.
Do you fabricate bodywork panels for classic or discontinued vehicles? Yes — this is one of the most common reasons customers come to us, particularly where original panels are no longer available to buy through normal parts suppliers.
Will bodywork corrosion affect my MOT even if it’s not structural? It depends on location. Corrosion near prescribed structural areas can cause an MOT failure even if it looks cosmetic, so it’s worth having any corrosion assessed properly rather than assuming it’s purely visual.
Do you offer on-site bodywork welding for larger vehicles? Yes — our on-site welding and fabrication service can bring the right equipment directly to your location for many bodywork jobs.
How quickly can I get a bodywork repair booked in? Turnaround depends on the scope of the job and current workload, but we always aim to assess and book vehicles in as quickly as possible.
