Model 73 - Small-Bore ID Pipe Weld Head0 pages
The widest range of orbital welding equipment in the world
The Model 73 weld head is designed to make
butt weld, cladding and weld overlay repairs
by remote control on the inside diameters
(ID) of piping and specialized valve systems.
The Model 73 is a smaller version of the
industry standard Model 43 weld head. It is a
rugged, field-proven weld head for use in
small diameter pipe and other limited radial
clearance applications.
The standard weld head is equipped with an AVC
(Arc Voltage Control), Torch Oscillation (weaving),
onboard Wire Feeder, and Travel for use in small
diameters. The weld head can also be equipped
with a remote arc viewing system and remote controlled wire manipulator (wire up/down and in/out)
that allow adjustment of the filler wire to electrode
relationship.
