Orbital Welding Applications



Orbital Welding, the most suitable method for faultless combining the ultra pure stainless steel pipe. We can plan, install and test pipelines according to your needs and train them to use.

Orbital welding is a specialized area of welding whereby the arc is rotated mechanically through 360° (180 degrees in double up welding) around a static workpiece, an object such as a pipe, in a continuous process. The process was developed to addresses the issue of operator error in gas tungsten arc welding processes. In orbital welding, computer-controlled process runs with little intervention from the operator. The process is used specifically for high quality repeatable welding.

It is very difficult to achieve the highest standards of quality and safety using manual welding. This is due to certain welding positions, overhead and down-hand welds for example, often leading to faulty welds due to restricted access the user has in these welding positions. In order to have complete control over the weld pool, a perfect balance must be maintained between gravitational force and surface tension at every position of the torch. By using mechanised variants of the technique, certain parts of the welding process are handled by mechanical components. Note that a welder will always be monitoring and controlling the process. In an ideal situation, all welding parameters would be fully programmed before welding is started. In practice, however, the presence of variable constraints means that it is often necessary for the welder to make corrective interventions.

Orbital welding can provide reliable welding of reproducible quality using wide-ranging techniques and differing types of technique. This can be performed to a high standard even when using unusual materials, thick walls, small tube diameters and even within a difficult working environment.

Owing to its ability to realise high purity results, orbital welding found its place in the production of clean-room components for the semiconductor industry. Its application has now expanded to the construction of pipework and equipment for diverse industries like food processing, pharmaceuticals, chemical engineering, automotive engineering, biotechnology, shipbuilding and aerospace.
