| The T-Head model weld
heads (Models 417 & 418) are "full function" - with the capability
of reproducing all the precise motions of a skilled manual GTAW
welder. They are specifically designed for multipass pipe welding
applications. These weld heads consistently produce welds meeting
the most stringent code quality standards. The T-Heads are ideal
for larger diameter/heavy wall pipe welding requirements.
Used with the Pipemaster Power Source Models,
these weld heads improve productivity by increasing duty cycle,
reducing repair rates and producing welds of consistent quality.
The T-Head is a rugged head for larger diameter /
heavy wall applications requiring precise welding process control of
GTAW.
WELD HEAD MOUNTING/ROTATION
The weld head is mounted on the pipe by means of
metal Guide Rings(patented), which are available for all standard
pipe / tube sizes. The weld head mounts entirely on one side of the
joint, allowing use for pipe-to-fitting welds.
FLX-TRACK
FLX-Track® allows long linear seam
welds on flat or curved surfaces, such as tanks and vessels
requiring precision GTAW welding. FLX-Track allows ID, OD, and
compound curvature welds to be made. Standard 2.3m (7.5') track
sections quickly interlock to form longer lengths and mount on the
workpiece using magnet, vacuum, or stud-gun attachment. The track
flexes to conform to different diameters, eliminating the need to
purchase special tracks for each new application. (For Model 418
only)
TORCH OSCILLATION (WEAVE)
The width and speed of the torch oscillation stroke
are independently programmed. Torch "Dwell" is independently
adjustable at both oscillation stroke end points. A "Cross Seam
Adjustment" steering control on the remote Pendant allows the welder
to track the torch on the weld seam without the need for manual
adjustments near the arc. Pulsed current is automatically
synchronized with torch oscillation when both functions are operated
simultaneously.
ARC GAP CONTROL (ARC VOLTAGE CONTROL)
The Arc Gap Control electronically maintains a
desired arc length as the torch rotates around the pipe.
USE ON PREHEATED PIPES
The T-Head drive system incorporates heat-tolerant
components and a water-cooled housing for use on CrMo and other
alloys requiring preheat. Mounting the head on an oversize Guide
Ring with adapter feet creates an air space, preventing heat damage.
