Text 2. What Is Orbital Welding
The term Orbital-Welding is based on the Latin word ORBIS = circle.
This has been adopted primarily by aerospace and used in terms of Orbit
(noun) or Orbital (adjective) for the trajectory of a man-made or natural
satellite or around a celestial body. The combination Orbital Welding
specifies a process by which an arc travels circumferentially around a work
piece (usually a tube or pipe). The concept Orbital Welding is basically a
loosely defined term that is usually used for processes only, where the arc is
travels at least 360 degrees around the work piece without interruption.
Consequently, processes, which interrupt the full 360-weld sequence such as
for better puddle control (often used for MIG/MAG welding, using the down-
hand welding sequence in 2 half-circles), can not truly be called orbital
welding.
Possibilities and Limitations
From welding terminology Orbital Welding belongs to the category
semi-mechanized (TIG-) welding. Because of the need for good control of the
weld puddle, the Orbital-Welding process is only practiced with the TIG
