When the hydraulic and fuel lines
on a single jetliner can total 700
assemblies, the golden ideal of
welding and of tube making is
identical: a faster weld at no sacrifice
in quality. Even orbital welding is
continually fine-tuned to deliver its
benefits at ever-higher speeds.
Tube makers have mastered welding
set-ups for rotation, dwell and
penetration parameters, different for
each size of tubing. They know how
to regulate a power supply for welding
current, primary and background
amperes, weld bead overlap, and for
delay of rotation at the start of the
weld and current downslope at the
end. They share with welders a zeal
amounting to passion for a clean cut-
off operation with smooth surfaces.
For as long as welding is the method
by which tube and pipe are joined, the
advances that lie ahead for the two
already highly developed technologies
will be made in tandem. In the
meantime, this partnership of equals
acknowledges a common obligation: to
provide perfect leak-tight joints having
uniform circumferential weld strength
to the automotive, defence, aerospace,
biomedical and machine tool industries
of the world.
