Orbital welding is a process where the welding arch is rotated continuously around the welded tube through at least 360°. After installing the head and adjusting welding parameters process is carried out in an entirely automated manner. Thanks to the ability to shape root welds (introducing gas into the tube) and achieve almost perfectly smooth face, welds do not require any further processing, therefore they meet highest technological standards.
The process requires very good welding pool control, this is why orbital welding has been carried out exclusively using TIG technique.
