Dedicated laser
welding line for orbitals
TAILORED Orbitals® from ThyssenKrupp Tailored Blanks feature
a function- and load-oriented structure precisely matched to the
conditions in the part. Unlike other tailored products, they are made
from tubular starting material, rather than from flat blanks.
The rotationally symmetrical parts are manufactured on a
dedicated laser welding line, on which up to five individual tube
segments can be joined together end-on. The individual segments
can consist of different materials such as carbon steel and stainless
steel, and can have different diameters, different wall thicknesses
and different coatings. The result is a starting material that is
optimised from the outset for a particular application.
Typical areas of use for Tailored Orbitals include car seats,
exhaust systems, cockpit support tubes and chassis parts. For
example, ThyssenKrupp Tailored Blanks has developed a tailored
orbital alternative for a rear seat back reinforcement made from a
conventional tube. The new solution reduces weight by around a
kilogram because the conventional structure is made from a tube
of uniform wall thickness, that thickness being determined by the
highest loads occurring in the part. The part made from a tailored
orbital on the other hand is of varying wall thickness. In the lower
third of the seat back, where the heaviest loads occur, the material
is 1.5 to 2.5mm thick. In the other areas, 1 to 1.5mm is sufficient.
Tailored Orbitals for shock absorber reservoir tubes achieve
claimed weight reductions of up to 30%. ThyssenKrupp Tailored
Blanks has developed a new solution for a current mid-size platform.
Unlike the conventional solution, with uniform wall thickness, the
Tailored Orbitals solution has a thickness of around 2.5mm only
in the highly stressed lower section of the tube. Further up, wall
thicknesses of well below 2mm are sufficient.
Tailored Orbitals can be fabricated just like conventional straight-
seam welded tubes. The orbitals do not have to be cut to length
first, because this is part of the manufacturing process, as is
machining of the tube ends. Dimensional tolerances are similar
to those of straight-seam welded tubes. In addition, Tailored
Orbitals can shorten production processes by combining several
manufacturing steps.
The orbitals are available in lengths of up to 2,500mm, and in
diameters that can vary between 30 and 90mm within one tube.
They can be made in all carbon and stainless steels suitable for
laser welding.
