Welding planned around the finished fabrication

Steel, stainless steel and aluminium joined into components and fabrications that fit the application. Our team considers the joint, access, material and weld sequence before work starts, with distortion and the finished dimensions in view. No drawing for the original? We can begin with reverse engineering from the sample.

Joined with care

Welding

Welded components and fabrications, planned around material, joint access and distortion control.

A sound joint starts with the whole design

Welding joins metal components into a fabrication, but the job is about more than laying a weld. Joint preparation, access, material condition, heat input and sequence all affect the finished result. MV reviews how the fabrication will be used and how it must fit its mounting points or mating parts. We choose an appropriate process for the material and joint, then agree the dimensional and visual requirements before making the work.

Choose the joining process

MIG, TIG or arc welding selected around the material, joint design and access.

Plan for distortion

The weld sequence and support of the parts are considered before heat is introduced.

Protect the important interfaces

Mounting faces, holes and locating features are considered alongside the fabrication work.

Check the finished fabrication

The completed work is checked against the requirements agreed for the application.

Rebuild an obsolete fabrication through reverse engineering

When a frame, bracket or welded unit has no drawing, our engineers can review the sample and recover the geometry that matters. Reverse engineering helps separate the intended shape from wear, damage or earlier repairs, so proposed changes can be agreed before the replacement is fabricated.

Keep manufacture and welding connected

Sheet metal work, machined components and welding can be coordinated within the same project. The team can review interfaces before the parts reach the welding stage.

Check what has to fit

We agree which dimensions, mounting points and other features need to be checked after welding and any finishing work.

Which materials can we weld?

We work with steel, stainless steel and aluminium. The exact grade, condition and joint requirements affect the welding approach, so our engineers confirm suitability before the job starts. Tell us about any coatings, previous repairs or unknown materials in the sample.

What finish does the weld need?

The finish should follow the function of the joint and the appearance required. A visible weld may be appropriate; another application may call for controlled blending or subsequent finishing. We agree that requirement before work starts because removing weld material or adding a coating can affect the joint or a nearby fit.

As welded

The weld remains visible. We agree the appearance and acceptance requirements appropriate to the fabrication.

Blended or finished

Where suitable, welds can be dressed or polished to the agreed requirement. Any subsequent coating is considered with the material and application.

Why engineers choose MV for welding

Our team looks at the finished fabrication, including how it is made, where it fits and what it needs to do. Welding can sit alongside reverse engineering, machining and sheet metal work within one project. That keeps the decisions about geometry, joints and assembly connected.

Welding FAQs

Welding questions, answered

Can MV reproduce a welded component from an existing sample?

Accordion toggle icon

A sample can support reverse engineering when drawings are missing. We assess its geometry, condition and the interfaces it must retain, then define a suitable replacement. The original weld arrangement is reviewed rather than copied automatically, particularly where damage or distortion contributed to failure.

What information is needed for a welding quotation?

Accordion toggle icon

Send drawings or photographs, material details, quantities and the required date. Include joint details, critical dimensions, finish requirements and the component’s working conditions. Where a code, qualification or inspection standard applies, provide it before quotation so its requirements can be assessed.

How is the welding process chosen?

Accordion toggle icon

The process is selected around the material, joint geometry, access, thickness and finished requirements. Appearance is only one consideration. Our engineers review how the weld must perform and how the surrounding component will be held, finished and checked before confirming the route.

How do you control distortion in a welded fabrication?

Accordion toggle icon

Welding introduces heat that can move the surrounding material. Joint design, support, weld sequence and allowances all influence the outcome. We review critical interfaces early and consider whether they should be machined after welding to achieve the required final relationship.

Can welded parts be machined afterwards?

Accordion toggle icon

Secondary machining can be included where mounting faces, bores or other interfaces require a controlled finished condition. The fabrication and machining stages must be planned together, including access and material allowance. Specify the dimensions that apply after all operations are complete.

Can you combine welding with sheet metal fabrication?

Icon

Sheet metal components can be incorporated into a welded fabrication where the design and material suit the process. Bends, joint access and heat input affect the manufacturing sequence. We review the complete part, including fasteners, finish and final assembly requirements.

Can a damaged welded component be repaired?

A repair needs an assessment of the damage, material and intended service. Some components are better replaced, especially where the cause of failure or original material cannot be established. Send clear photographs and usage details so we can advise on the next review step without assuming a repair is suitable.

What inspection should I request for a weld?

Inspection should follow the component’s function and any applicable specification. Visual appearance alone does not establish that a weld meets every performance requirement. Tell us which acceptance criteria or testing obligations apply so their availability and scope can be confirmed before work begins.

Can the finished fabrication be coated or otherwise finished?

A finish can be planned around corrosion exposure, appearance, cleaning and subsequent assembly. Surface preparation and inaccessible areas should be considered before the fabrication is made. Identify surfaces that must remain uncoated or maintain a particular fit in the finished component.

Do you take one-off welding jobs and production batches?

Both can be assessed against the same engineering brief. Quantity influences the value of dedicated fixtures and the most practical manufacturing sequence. Send the component details and expected repeat demand so the quotation reflects the whole requirement rather than only the first unit.
