Valves and Components

Welding Alloys’ Solution 

  • Expert knowledge and equipment for specialised cladding and repairs of complex parts and shapes often found inside valves and valve components.
  • Localised cladding and repairs with custom-fit consumables to reduce wear where needed, e.g. reduced wear by cavitation in some areas and abrasive wear in other areas of the same valve through the use of different consumables.
  • A large variety of consumables including cobalt based, nickel based and stainless steels.
  • Cost and time savings from repairing worn or damaged components, instead of these having to be replaced.


Replacement parts in exotic materials and even standard materials can be costly and could take months to be delivered, possibly resulting in excessive down time, or the need for increased stock holding of components and spare parts by the equipment owner.

Our technical know-how, combined with our specialist welding personnel and consumables, ensures fast and reliable repair welding of valve and valve components. These repairs often surpass the wear and corrosion resistance of the base material. In addition to repairs, full cladding of components is also carried out, allowing for the use of less expensive and exotic base materials.

Consistency and Customer Service

Our Integra™ engineers can utilise Welding Alloys consumables and automated welding equipment to respond quickly to the customer’s needs and guarantee a consistent high quality finish. Welding Alloys implements strict procedure controls to ensure we carry out repairs of the highest possible standard within the time frame available.
