Orbital welding

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. This method and technology was developed to address the issue of operator error in manual gas tungsten arc welding (GTAW) applications requiring precision tube and pipe welding. To ensure high-quality repeatable welds a more stringent weld criteria was set by the ASME.

In orbital welding, an automated computer-controlled process runs with little intervention from the operator.
