The
HUAHENG HDV32-TIG
circumferential
seam
adopts
the
single-torch
TIG
welding
method
and
is
mainly
used
for
circumferential
seam
welding
in
forms
such
as
pipe-flange,
pipe-fitting,
and
pipe-elbow.
Features:
Different
from
the
traditional
chuck-type
clamping
welding
equipment
on
the
market,
the
disc
drive
mechanism
of
this
equipment
adopts
a
lifting
mode,
which
can
reduce
the
auxiliary
time
for
welding
and
improve
the
welding
efficiency.
The
control
system
has
a
built-in
WPS
expert
parameter
database
and
a
function
for
retrieving
commonly
used
pipe
materials.
It
possesses
the
OSC
(Oscillation
in
Arc
Length)
and
AVC
(Arc
Voltage
Control,
Arc
Length
Tracking)
technologies,
and
can
adopt
the
hot
wire
TIG
process.
Moreover,
it
can
realize
the
functions
of
multi-layer
and
multi-pass
continuous
welding
and
automatic
root
pass
welding
through
the
human-computer
interaction
interface,
greatly
reducing
the
operation
difficulty.
