Our welding capabilities range from manufacture of high integrity stainless steel fabrications to automated robotic welding cells for high volume manufacture of repeatable, critical components.

We have extensive experience in fabrication and welding, allowing us to provide a complete service to our customers. We supply the highest quality finished products in our ISO 3834 accredited welding facility, managed by our European and Internationally certified Technical Welding Manager.

Our welding capabilities range from manufacture of high integrity stainless steel fabrications to automated robotic welding cells for high volume manufacture of repeatable, critical components. For the petrochemical sector, we excel at overlaying hard-facing/corrosion resistant alloys. For the power generation sector, we excel at the fabrication of high pressure, high integrity welds, joining dissimilar materials.

As well as welding, we also have a broad range of heat treatment capabilities. The application of heat treatment is most common following the welding of overlays or fabrications. Post Weld Heat Treatment (PWHT) is undertaken to relieve stresses caused by welding within certain materials. At our disposal, we have electric and gas ovens along with more specialised induction heating systems that are PLC controlled to within 1°C accuracy. Such systems are capable of heating thick walled sections to 750°C for extended periods with very high degrees of temperature stability and control.

Data recorders are used to record temperature rise, dwell times and cooling times. We have the capability to provide our customers with hard copy of electronic versions of this information upon request. All furnaces and data recorders are regularly calibrated as part of our comprehensive calibration system.

Dependent upon the material and weld procedure, a water quench heat treatment may be required. This is performed at our sister company, Goodwin Steel Castings (GSC), who work to the same exacting standards as us. GSC has at their disposal a 50 tonne water quench heat treatment facility and large standard furnaces available.
