Types of Welding

We offer a comprehensive range of welding services, including:

  • TIG Welding (Tungsten Inert Gas) – Provides precise control, ideal for thin materials and critical welds.
  • MIG Welding (Metal Inert Gas) – Suitable for thicker materials, offering speed and efficiency.
  • MMA Welding (Manual Metal Arc) – Versatile and effective for various metals and conditions.
  • Submerged Arc Welding – Used for thick materials, providing deep weld penetration and high-quality results.
  • Robotic Welding – Ensures consistency and efficiency in repetitive welding tasks.

Our extensive range of welding techniques enables us to select the most appropriate method for each project, ensuring optimal results.

Case Studies

Explore a selection of our recent metal fabrication projects, demonstrating the breadth of sectors we serve and the exceptional standards we uphold. Each case study showcases our expertise in delivering complex, high-precision fabrications, ranging from structural steelwork to bespoke stainless steel components, tailored to meet our clients’ exact specifications.

Combustion Exhaust Lined Duct

WEC Fabrication recently completed the manufacture of a specialist Combustion Exhaust Lined Duct for an aerospace application. The duct forms part of a combustion exhaust system for an aerospace application. It is designed to support the safe and effective movement of exhaust gases through the system.


The project involved the fabrication of 12 individual sections, which together formed an overall duct length of 25 metres. With a diameter of approximately 4.62 metres, the finished structure required careful planning, skilled fabrication and precise coordination throughout the manufacturing process.

Wave Machine

Our WEC Fabrication Division recently completed the welding and fabrication of a large wave machine structure at our Darwen facility. The project required the production of a heavy-duty chamber design to integrate with systems used to generate controlled wave motion for testing and research purposes.

Our team delivered the full fabrication package in house, from preparation and forming through to welding and final assembly.

Multiple flanged connections were incorporated into the design to allow integration with pumping and control systems responsible for generating and regulating wave movement within the system.
All welding was completed by our coded welders, ensuring the finished structure met the required standards for strength, durability, and long-term performance.

Trommel Mixing Drum

The Trommel Mixing Drum was manufactured at our WEC Fabrication’s facility in Darwen using a combination of specialist machinery and highly skilled fabricators.

Our workshop is equipped to handle large and complex fabrications, including:

• Craneage capabilities of up to 40 tonnes
• Advanced robotic welding systems
• High-capacity plate rolling equipment
• Precision cutting and forming machinery

These capabilities allowed our team to fabricate the cylindrical drum sections with accuracy, ensuring alignment and high-quality weld integrity throughout the structure.

Blast Baskets for Aero Engine Test Beds

Project: Blast Baskets for Aero Engine Test Beds
Client: Rolls Royce
Location: Derby, East Kilbride, Cardiff

WEC Group has fabricated and installed multiple Test Beds for various organisations such as Rolls Royce (Test Bed 54 and 80), General Electrics based in Wales and BAE Systems in Scotland.
One of our most recent projects is a 17m long x 6.5m diameter blast basket for the worlds largest indoor engine test bed facility at Rolls Royce, Derby.

The testbed will support engines such as Trent XWB and Trent 100 and will also be able to facilitate the UltraFan, which is Rolls Royce’s engine for the next generation of aircraft.

Silence Control Exhaust Stack Fabrication

Sector: Energy
Project: Silence Control Exhaust Stack
Location: Aberdeen

WEC Fabrication successfully completed the manufacture of a high-specification Silence Control Exhaust Stack for a key customer in the energy sector. Designed and fabricated to meet exacting requirements, this complex structure was delivered within a strict 16-week lead time, ensuring it was installed on schedule during a planned site shutdown in Aberdeen. Constructed from a combination of 321-grade perforated stainless steel and carbon steel, the exhaust stack was built to withstand high temperatures and demanding environmental conditions. The structure comprised 10 separate fabrications, each measuring approximately 4.2 metres wide and weighing over 5 tonnes. Once fully assembled, the stack was meticulously insulated with glass fibre to enhance thermal efficiency and noise reduction.

Arches of Oman

Project: Arches of Oman
Artist: Giles Rayner
Location: Muscat, Oman

Our architectural metalwork division, m-tec, was commissioned to fabricate a striking 12-metre-high architectural stainless steel water feature, now a centerpiece in the private gardens adjacent to the Royal Opera House in Muscat, Oman. Designed by renowned sculptor Giles Rayner of GR Sculpture Ltd, the sculpture embodies a seamless blend of artistry and engineering. The Duplex stainless steel structure was meticulously fabricated and polished by m-tec’s expert engineers at their UK headquarters. The project took three and a half years from concept development to final installation, with rigorous quality control at every stage.
