Orbitalum: Welding stainless-steel pipe elbows at the push of a button Pneumatic clamping – patent for 6-fold higher productivity Enormous savings, high sustainability Even with the very first generation of the orbital weld head
HX 16, Orbitalum Tools GmbH from Singen in Germany
revolutionized the welding of pipe elbows in fin heat exchangers:
"HX" stands for heat exchanger. Now the company has perfected
its worldwide unique weld head even further and has extended it
into a series: At the push of a button the HX 16P and HX 22P
clamp themselves on the pipe by means of a patented pneumatic
clamping mechanism.
Through this innovation both handling and comfort have been
improved markedly and furthermore the efficiency, cost
effectiveness and quality of the weld result have been increased
notably. Orbitalum thus makes it possible for the HVAC (Heating
Ventilation Air Conditioning) industry to change over more easily
from traditional heat exchangers made of copper to stainless
steel. Stainless steel fulfills the regulations (to F-gases directive)
up to climate-friendly refrigerants.
Stainless steel can only be joined particularly economically,
reliably and with high quality using tungsten inert gas (TIG)
welding in conjunction with mechanized orbital welding. All
closed orbital weld heads or open weld tongs commonly

available on the market are not suitable, as their construction
makes placement between the individual pipes impossible.
Thanks to its outer diameter of only 60 millimeters, a pipe
spacing of only
30 millimeters is sufficient for the HX 16 from Orbitalum for
positioning and clamping at the push of a button.
New users speak of an increase in productivity of six-fold. This
makes it possible to accelerate the procedure of aligning the
weld head and clamping the head by 10 to 15 seconds per
welding cycle. About 1.5 minutes pass per working cycle at a
pipe with 16 millimeter outer dimension and 0.5 millimeter wall
thickness: Clamping, establishment of the inert gas atmosphere,
welding, cooling down in the argon atmosphere, which prevents
annealing colouring of the weld seam. In the past the operator
has to support/hold the weld head by hand during the welding
process. Thanks to the pneumatic clamping the head holds its
position at the pipe elbow by itself. This makes it possible for a
less experienced operator to produce welds with up to three weld
heads (systems) at the same time per cycle.
A further plus for the HX 16P orbital weld head (pipe outer
diameters 15 to 16.8 millimeters) and for its big brother HX 22P
(pipe outer diameters 19 to 22 millimeters) is the closed welding
chamber which means that almost no annealing colours can form
in the heat-affected zone of the weld seam. This means that the
user achieves an enormous saving and simultaneously
inestimably high sustainability: No annealing colour means no
pickling and no passivating. Companies that do not carry out
pickling themselves save comparatively high costs for the
transport to and from the heat exchanger.

The current model HX 16P has already convinced users in
Germany, Italy, Spain, China, India, Korea, Brazil and Mexico –
after all higher degrees of automation also means high
productivity.
This design-based advantage also makes the Orbitalum system
the ideal tool for cost-effective repairs of heat exchangers.
Thanks to their low weight and the well-established Orbitalum
hose package with all the connections for electricity, gas and
cooling liquid, the HX 16P and HX 22P heads are extremely
useful.
All welding power sources from Orbitalum automatically
recognize these heads and their properties so that the operator
only has to call up their specified welding program and start the
process before beginning to weld.
In 2017 the HX product family will be supplemented by a further
model: The HX 12P welds pipes from 9.52 to 12.7 millimeters
diameter and thus completes the portfolio of Orbitalum Tools
GmbH.

New F-gases directive and high copper prices – the manufacturers are switching over to stainless steel. A pipe spacing of 30 millimeters is sufficient for positioning and clamping of the orbital weld head at the push of a button.
