Model 52 Heavy Duty Precision Weld Head0 pages

The widest range of orbital welding equipment in the world
The Model 52 is engineered and designed
for high-deposition circumferential and flat
welding in heavy industrial and harsh field
applications where quality requirements are
stringent and the use of the GTAW process
is beneficial. It is intended for all-position,
automated welding of pipe, plate or fittings
using the Cold or Hot Wire Feed GTAW (TIG)
process.
The Model 52 weld head provides all functions
necessary for high-quality orbital pipe welding and
other elements required for an automated pipe
welding system, such as precision guide rings, and
one of several AMI Power Supplies.
