Welding, Machining and Fabrications for Renewable Energy Projects

Renewable Energy

Arc Energy Resources provides weld overlay cladding, fabrications and CNC Milling/Turning for components in the Hydro, Geothermal and Tidal power generation industries.

We specialise in corrosion resistant weld on layers that form a protective barrier inside pipelines, valves, flanges and specialist fabrications known as ‘weld overlay cladding’. This process can be used in hydro power turbines, protecting the inside of pipes against the corrosion effects of forced falling water, salts and other detritus. Arc Energy’s weld overlay cladding can also be used to reduce the damaging effects of cavitation, the phase changes that occur from pressure changes in a fluid to form bubbles, resulting in noise or vibration in the water column. The implosion of these bubbles against a solid surface, such as a hydraulic turbine, may cause erosion and lead to reductions in capacity and efficiency pressure.

Arc Energy’s welding engineering team will be able to aid in deciding on the ideal weld overlay combination to use. Typical welding alloy materials in common use at Arc Energy include Inconel 625, Inconel 825, monel, hastalloy and stainless steels amongst many others. Our specialist welding can also help with the protection of tailraces once the water has been through the turbine and heads back to the river.

CNC Milling/Turning work

Alongside our welding we also offer specialist CNC Milling/Turning and are able to turn components within tolerances +/- 0.0127mm and a range from 25mm up to 1.25 metres, across a wide range of materials, including: nickel alloys, aluminium alloys, titanium, mild & stainless steels, nylons and plastics.

Specialist fabrications

We can fabricate spools, pressure vessels, well head equipment and subsea piping with all our work carried out in accordance with our quality management system certified to ISO 9001 and our welding management system certified to ISO 3834-2.
