Welding & Fabrication
Our certified welding services support the fabrication and repair of expansion joints, bellows and associated pressure components, as well as pipework and pressure vessels. We specialize in TIG, MIG and Sub-Arc welding for carbon steel, stainless steel and other exotic alloys. All welding is performed to the most relevant industry standards required to ensure structural integrity, leak-tight performance and long-term durability in high-pressure and high-temperature environments.

What We Weld & Fabricate
Our welding and fabrication capability supports both new manufacture and repair work, including:
-
Expansion joint fabrication and repair, including associated frames, hardware and interfaces;
-
Bellows-related components and supporting structures (as part of engineered assemblies);
-
Pipework fabrication, including spool work and equipment connections;
-
Pressure components, where integrity and inspection scope are critical;
-
Pressure vessel fabrication and repair (scope defined by specification and project requirements).
If your requirement is a complete engineered assembly, we can integrate welding with machining, fitting, inspection and testing so the delivered component fits and performs as intended.
Welding Processes & Materials
Welding Processes
We specialise in:
-
TIG welding for controlled, high‑integrity welds;
-
MIG welding where appropriate for productivity and repeatable quality;
-
Sub-Arc welding for where it is the best-fit process, such as in heavy pipework;
-
And other welding methods where necessary.
The process selection is duty-led: material, thickness, joint geometry, access, distortion control, and required inspection regime all influence the approach.
Welding Materials
We weld and fabricate using:
-
Carbon steels and steel alloys for end fittings such as flanges;
-
Stainless steels for the flexible bellows components themselves;
-
Specialist alloys also for bellows component where specified for temperature, corrosion-resistance or mechanical performance;
-
Titanium or aluminium under very specific circumstances in which it is optimal.
If you have a specific grade requirement, send it with your enquiry and we will align procedure and inspection scope to that specification.
Quality, Standards & Leak-Tight Performance
We support delivery aligned to your project requirements, typically including:
-
Welding carried out to relevant industry standards as required by specification (often, but not only, ASME IX and ISO);
-
Weld procedure and qualification approach appropriate to the duty (as specified);
-
Fit-up and distortion control to protect alignment and sealing performance;
-
Inspection and documentation packages matched to project and sector expectations.
Where weld integrity is critical, we encourage defining inspection and test requirements early so they are built into the plan rather than discovered late.
Inspection, NDT & Testing Support
Depending on what your specification requires, welding and fabrication work can be supported with inspection and test scope such as:
-
Weld inspection and verification;
-
Non‑destructive testing, including radiography and other methods where specified;
-
Pressure testing and leak testing, where applicable to the assembly and required by the project;
-
Documentation packs supporting traceability and release requirements.
If your project requires a specific testing regime, include it in your enquiry so lead time and scope can be confirmed accurately.
Typical Applications & Sectors
Our welding and fabrication services are commonly used in projects where performance and durability matter, such as:
-
High‑pressure and high‑temperature systems;
-
Power generation and CHP utilities and critical connections;
-
Marine and offshore environments, where access is limited and reliability is essential;
-
Oil and gas and LNG skids and modular pipework systems.
Industrial process plant pipework and pressure-related fabrications.
Repair & Refurbishment Capability
Welding and fabrication is frequently required for maintenance and repair scenarios, for example:
-
Repair of damaged or leaking assemblies where safe and practical;
-
Restoration of interfaces, frames or pipework sections;
-
Controlled fabrication work during shutdown windows.
If your requirement is driven by downtime, include your shutdown date and constraints so we can advise the most practical route and whether FastTrack handling is appropriate.
How To Request A Quote
To quote welding and fabrication work quickly, please send:
-
Drawings, isometrics, or a clear description of scope (photos help for repair work);
-
Material grades and any project-specific standards or code requirements;
-
Operating pressure and temperature where relevant to scope definition;
-
Required inspection and testing scope (NDT, pressure testing, leak testing);
-
Documentation expectations (traceability, inspection records);
-
Quantity, delivery expectations, and any shutdown or critical dates.
If you are unsure what inspection scope you need, send the specification or project requirement and we will help interpret it into a practical plan.
FAQs About Welding & Fabrication
Do you provide certified welding to the relevant industry standards? Yes. Welding is performed to the most relevant standards required by your project specification, with inspection and documentation scope aligned to those requirements.
Which welding processes do you offer: TIG, MIG and Sub-Arc? We specialise in TIG, MIG and Sub-Arc welding, selecting the most appropriate process for the job, particularly in regards to the material.
Can you fabricate and repair expansion joints, bellows and associated pressure components? Yes. We support both manufacture and repair work across expansion joints, bellows-related assemblies, pipework and associated pressure components, subject to project scope and feasibility.
Can inspection, NDT and leak-tight testing be included? Yes. Inspection and NDT can be included where required, and pressure or leak testing can be planned where applicable to the assembly and specification.
What do you need from me to quote welding and fabrication work quickly? A drawing or photos, material grade, duty conditions where relevant, inspection and documentation requirements, and your delivery or shutdown deadline.
