What is Orbital welding
Oct 06, 2016

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 (GTAW). In orbital welding, computer-controlled process runs with little intervention from the operator.The process is used specifically for high quality repeatable welding. 


The main components of every orbital welding system are the power source and controller, the welding head and, where required, a wire feed mechanism. Welding of certain sizes and material types will also require the use of a water/coolant system. There are a large number of factors that can have an influence on the welding result. These aspects include the arc length, magnitude and pulse frequency of the welding current, welding speed, inert shielding gas, parent material, filler material, weld preparation, and thermal conductivity. Ultimately, a high quality weld is achieved through detailed knowledge of how to precisely adjust all these parameters for each individual welding task.
