Corrosion Resistant Alloy (CRA) Welding Overlays

We make overlay of Corrosion Resistant Alloys by welding, such as welding overlay of Inconel 625 for Sour Service Ball Valves (with high content of H2S). The welding overlay is a key process which, according to our experience, it is strongly recommendable to be performed and controlled in-house in order to provide the most advanced quality product within the required timeframes.

For this purpose, we perform this process in-house by means of state of the art welding machines to weld Corrosion Resistant Alloys, and our highly skilled and experienced welding team led by an International Welding Engineer. All the process is carried out according to the established procedures, monitoring and supervising strictly the key parameters through the process, in order to ensure the quality and reliability of the welding. Prior, during and after welding we perform all the subsequent test and quality checks in order to ensure the good quality of the overlaid valves.
