Car Welding & Fabrication
Skilled MIG welding for MOT repairs, structural work and custom fabrication. Done properly, priced fairly.
Whether your car has failed its MOT on corrosion, needs structural chassis work, or you need a custom bracket fabricated, our team has the skills and equipment to get the job done right. We carry out MIG welding on sills, floor pans, chassis legs, subframes, exhaust systems and body panels — using proper repair techniques, not bodge jobs.
Every welding repair is carried out to a high standard with clean, solid welds that will last. We cut out the damaged metal, prepare the surfaces properly and weld in new material. No filler hiding rust, no quick patches that fall apart six months down the line. Typical welding jobs take around 2 hours.
What Types of Automotive Welding Exist?
Automotive welding encompasses several different techniques, each suited to specific applications on a vehicle. MIG welding, which stands for Metal Inert Gas, is the most commonly used method in car repair and the primary technique we use at Demon Autos in Milton. MIG welding uses a continuous wire feed and shielding gas to produce clean, strong welds on mild steel and stainless steel components. It is versatile enough to handle thin body panels without burning through, yet strong enough for structural repairs on chassis rails and subframes.
Arc welding, also known as stick welding, is used for heavier structural applications where deep penetration and maximum strength are required. This technique is particularly useful on thicker steel sections found on chassis legs, tow bars and heavy-duty mounting points. TIG welding offers the most precise control and is used for specialist applications like exhaust manifold repairs and thin stainless steel work. At our workshop near Norton Green and Burslem, we select the appropriate welding method based on the material thickness, the component being repaired and the structural requirements.
Spot welding is another technique commonly used in automotive repair, particularly when replacing body panels that were originally joined at the factory using resistance spot welds. When fitting a new sill section or wheel arch repair panel, we replicate the factory spot weld pattern to maintain the structural integrity of the join. Understanding which welding method to use and when is critical to producing repairs that are safe, durable and pass MOT inspection. Poor welding technique can weaken a structure rather than strengthen it, which is why skilled, experienced welders are essential.
How Does MOT Welding Work?
MOT welding repairs are one of the most common reasons vehicles in Stoke-on-Trent require welding work. During an MOT test, the examiner checks the structural condition of key areas including sills, chassis legs, floor pans, suspension mounting points and outriggers. If corrosion has weakened these components to the point where structural integrity is compromised, the vehicle will fail its MOT. The advisory or failure notice will specify exactly where the corrosion is and what needs to be repaired before the vehicle can pass a retest.
At Demon Autos, we regularly carry out MOT welding repairs for drivers across Milton, Smallthorne, Abbey Hulton and the surrounding areas. The process involves cutting out all corroded and weakened metal, cleaning back the surrounding area to sound material, and welding in new steel sections that match the original thickness and profile of the component. We do not simply patch over rust with thin metal and filler, which is a common bodge that fails again within months. Our repairs are done properly with clean, solid welds that restore the full structural strength of the repaired area.
After welding, we grind the welds smooth where necessary, treat all bare metal with rust-preventive primer and apply protective coatings to guard against future corrosion. Road salt, standing water and the general Staffordshire climate mean that vehicles driven regularly around Burslem, Carmountside and Eaton Park are particularly susceptible to corrosion on their underside components. A proper MOT welding repair, done right the first time, should last for years rather than just scraping through one more test. We are happy to show you the completed repair before any cosmetic finishing so you can see the quality of the work.
When Does a Car Need Structural Welding?
Structural welding is required whenever a load-bearing component of the vehicle has been damaged by corrosion, impact or fatigue. The most common structural welding jobs we carry out at our Milton workshop include sill replacements, chassis rail repairs, subframe reinforcement, suspension turret repairs and floor pan sections. These components form the structural skeleton of your vehicle, and any weakness in them compromises the car's ability to protect occupants in a collision. If you notice rust bubbling through the paint on your sills or under the doors, it is worth having it inspected sooner rather than later.
Accident damage can also necessitate structural welding. Even a relatively low-speed impact can bend, crack or deform structural components that need to be repaired or replaced to restore the vehicle's crashworthiness. Drivers across Norton Green, Burslem and Stoke-on-Trent who have had a bump in a car park or a minor collision should have the affected area properly assessed. Sometimes what looks like cosmetic panel damage on the surface conceals structural deformation underneath that needs professional attention to ensure the vehicle is safe.
Fatigue cracking is less common but does occur on older vehicles and those used for heavy towing or load carrying. Repeated stress on mounting points, brackets and chassis sections can cause hairline cracks that gradually worsen over time. If your vehicle makes unusual creaking or knocking noises from underneath, particularly on rough roads around Smallthorne and Abbey Hulton, it may be worth having the underside inspected. At Demon Autos, we assess structural damage honestly and carry out repairs that restore the component to its full original strength, never just a cosmetic cover-up.
Why Choose Demon Autos for Welding?
Welding quality matters enormously on a vehicle because it directly affects structural safety. At Demon Autos & Recovery on Milton Road, we have the skills, equipment and experience to carry out automotive welding to a high standard on all types of vehicles. Our welders understand the difference between a weld that looks neat and a weld that is structurally sound, and we prioritise strength and penetration over cosmetic appearance. Every repair we carry out is designed to last, not just to get through the next MOT test by the smallest margin possible.
We are straightforward about what your vehicle needs. When you bring a car to us for welding assessment, we will show you exactly where the problem is, explain what needs to be done and give you a clear, upfront price before any work begins. If the repair is not economically viable, for example if the welding cost would exceed the value of the vehicle, we will tell you that honestly rather than taking on a job that does not make financial sense. Drivers across Carmountside, Eaton Park, Norton Green and the wider Stoke-on-Trent area appreciate this no-nonsense approach.
Our workshop is equipped for all types of automotive welding from small exhaust patches to full sill replacements and chassis rail fabrication. We carry a stock of common repair sections and can fabricate custom brackets and mounting points to order. Pricing starts from around sixty pounds for minor welding jobs, with larger structural work quoted on inspection. We are open Monday to Saturday from 9am to 5pm, and you can book online or call us on 07459 759160. If your car needs welding, come to a garage that does the job properly first time.
