In the orbital welding process, tubes/pipes are clamped in place and an orbital weldhead rotates an electrode and electric arc around the weld joint to make the required weld.  An orbital welding system consists of a power supply and an orbital weldhead.

Power Supply: The power supply / control system supplies and controls the welding parameters according to the specific weld program created or recalled from memory.  The power supply provides the control parameters, the arc welding current, the power to drive the motor in the weld head and switches the shield gas(es) on/off as necessary.

Weld Head: Orbital weld heads are normally of the enclosed type and provide an inert atmosphere chamber that surrounds the weld joint.  Standard enclosed orbital weld heads are practical in welding tube sizes from 1/16 inch (1.6mm) to 6 inches (152mm) with wall thickness’ of up to .154 inches (3.9mm).  Larger diameters and wall thickness’ can be accommodated with open style weld heads.
