MIG, TIG and spot welding across mild steel, stainless steel and aluminium: structural joints, stainless welds and cosmetic work where the weld is part of the finished appearance.
Overview
Welding chosen for the duty, not for convenience
Welding is the process most often specified badly on a drawing and most often blamed afterwards. Process, filler, preparation, sequence and distortion control are decided by what the joint has to do: carry load, hold pressure, survive a wash-down regime, or simply look right under a spotlight.
The works holds MIG, TIG and spot welding capability. TIG is used where the weld is visible, where the material is thin, and for stainless and aluminium work where heat input and contamination control matter. MIG carries the structural and higher-deposition work. Spot welding covers sheet assemblies where a fusion weld would distort the panel.
Distortion is managed by sequence and by jigging rather than by straightening afterwards. On assemblies that have to fit existing structure, we trial-assemble before despatch.
Capability
Structural welding on frames, platforms, chassis and support steelwork
Stainless welding where surface finish and corrosion resistance are part of the specification
Aluminium TIG welding for lightweight structures and vehicle work
Cosmetic welding where the joint is visible in the finished product
Spot welding of sheet assemblies and panel work
Repair welding, modification and reinforcement of existing fabrications
Applications
Typical work
Access platforms, walkways, staircases and balustrades
Stainless steel staircases, balustrades and architectural metalwork
Racing car chassis and motorsport structures
Vehicle, trailer and horsebox interior metalwork
Broadcast and theatrical structures, including moving and folding assemblies
Repair and modification of existing customer fabrications
What we need
To quote accurately
A drawing showing joint types, weld sizes and any weld symbols
Material grades for every part in the assembly
Whether the weld is structural, pressure-retaining or cosmetic
Any welding procedure, welder coding or inspection standard that applies, so we can tell you early if the work needs a coded shop
Finish requirement: ground flush, dressed, linished, polished or as-welded
Whether trial assembly against existing structure is needed before despatch

one question than quote round a gap.
Process selection
Chosen for the duty, not for convenience
Welding is the process most often specified badly on a drawing and most often blamed
afterwards. This is how the three are actually chosen.
MIG
GMAW
Structural and
higher-deposition work. Frames, platforms, chassis and support steelwork where deposition
rate and penetration matter more than appearance.
TIG
GTAW
Where the weld is
visible, where the material is thin, and for stainless and aluminium where heat input and
contamination control decide the outcome.
Spot
Resistance
Sheet assemblies and
panel work where a fusion weld would distort the panel and no amount of dressing would
recover it.
Welding
Distortion is managed by sequence and jigging, not by straightening afterwards.
On assemblies that have to fit existing structure, we trial-assemble in the works before anything is loaded onto a lorry.
No. We do not hold welder coding or approved welding procedures, and we do not undertake work that requires them. If your specification calls for welders qualified to BS EN ISO 9606, procedures qualified to ISO 15614, or third-party inspection against a coded procedure, you need a coded shop, and we will tell you that at enquiry rather than at delivery.
MIG where deposition rate and penetration matter more than appearance: frames, platforms, chassis and support steelwork. TIG where the weld is visible, where the material is thin, and for stainless and aluminium, where heat input and contamination control decide the outcome. Most real assemblies use both, chosen joint by joint rather than for the whole job.
Yes. TIG on both, with resistance spot welding available on sheet assemblies where a fusion weld would distort the panel. On stainless the specification usually needs to state the finish as well as the joint, because a weld that is structurally perfect can still be rejected on appearance.
By sequence and by jigging rather than by straightening afterwards. Weld sequencing, staggered and back-step technique, and fixturing where the assembly justifies it. Straightening after the fact is slower, less reliable, and on a visible fabrication it usually shows. On assemblies that have to fit existing structure we trial-assemble before despatch.
Yes, in the works or on site. Repair welding, reinforcement and modification of installed metalwork are ordinary work here. See site and project support. Photographs of the existing item, and of how it failed, are the most useful thing you can send.
Not in-house. Independent testing (dye penetrant, magnetic particle, ultrasonic or radiographic) can be arranged through established supply-chain partners where a specification calls for it. Say so at enquiry so it is priced into the job rather than discovered halfway through it.

Rarely one process on its own
Most jobs cross two or three disciplines. Quoting them together removes handling,
transport and the interface risk that comes with splitting a job across suppliers.
