Spiral Welding
Our state of the art purpose built spiral welding facilities are suitable for jobs from 25mm up to 1600mm in diameter and up to 6m long. The unit is multi-process enabling open arc, submerged arc and gas shielded welding to take place. The process is digitally controlled and is fully programmable ensuring accuracy and repeatability. Work piece manipulation is synchronised with the movement of the weld head giving a precise and consistent application of material ensuring the best possible quality of job.
With approvals from Shell and DNV for a range of carbon and stainless steels and the ability to use materials such as Hastalloys and inconels, the spiral welding process not only allows for the repair of a component but can also improve the basic properties and enhance its life and performance. Spiral welding is also quicker than remanufacturing a shaft so reducing downtime.
All components and materials are fully treated and inspected with the required heat treatment and non destructive testing before and after the spiral welding process to ensure the surface is free from porosity and underlying defects once finish machined.
