Fibre laser welded tube mill for USA
YODER Manufacturing of Cleveland,
Ohio, USA, has supplied a QVW-150
fibre laser welded tube mill for producing
decorative stainless components up to
38mm (1½") diameter.
The complete system consists of an
entry end, forming machine, fibre laser
welder with twin-spot welding head,
sizing machine with integrated double cut
shear system, brush de-burring system
and a triple head centreless finishing
system, all fully integrated for ease of
operation. The mill also includes an ID
marking system, so the tubing coming
off the mill will be complete, ready to be
accurately located and welded into the
customer’s fabricating assembly.
By de-coupling the finishing system
after the cut-off, and utilising centreless
brush technology, instead of an inline
solution, the customer will be able to
easily vary their type of polished or
brushed finish, for the various products
that they supply to different end markets.
This can be done with the tube mill still in
operation, and accumulating in process
tubes, effectively maintaining continuous
throughput of the overall system.
This method of finishing, combined with
the laser welding system, will enable the
user to have one system instead of two
TIG welding tube mills. It is claimed that
the efficiency of this solution has enough
available production capacity that the
customer will be able to delay the need
for additional tube making equipment by
several years.
Yoder has provided similar systems,
in recent years, for the chemical, oil and
gas, and automotive markets, which
require the integration of non-destructive
testing and/or annealing equipment,
depending on the specific application.
For this latest tube mill, Yoder
developed its new fibre-based fusion
welding system with twin-spot welding
optics. With these latest developments,
laser welding is becoming more robust
for the tube mill environment and less
costly to operate when compared to CO
2
counterparts, as well as TIG/plasma
welding. With the new fibre laser welding
system there is no theoretical limit to tube
diameter, and with this system the wall
thickness capability has been practically
expanded to 9.5mm (0.375").
Yoder designs and builds equipment,
tooling and systems for metal forming,
tube and pipe and heavy industrial
material handling applications. The
company can provide both engineered-
to-order and off-the-shelf manufacturing
solutions that increase production
capacity and efficiency through
integrated, streamlined processes,
automation and faster machines.

Change at the head of Paul Wurth
MARC Solvi, chief executive officer of
Paul Wurth SA since 1998, will resign
from his function as of 31 December
2014, but will remain a member of the
company’s board of directors.
Georges Rassel, who has been active
at Paul Wurth since 1988, and chief
operations officer since 2011, has been
appointed by the board of directors as
Mr Solvi’s successor.
Michel Wurth, chairman of Paul
Wurth’s board of directors, commented,
“Marc Solvi has, during the last 17 years
with his work as chief executive officer,
contributed decisively to the growth and
successful economic development of our

took a majority stake in 2012, he helped
to significantly shape the integration into
SMS and, consequently, laid the basis
for a next step in the company’s further
development. We respect his personally
motivated decision to resign as chief
executive officer by the end of the year.
We welcome very much that he will
continue to accompany the company’s
development with his years of experience
as member of the board of directors.”
Located in Luxembourg since
its creation in 1870, the company
Paul Wurth designs and supplies
technologies and installations for the
iron making industry.
At a regional level, the company
is also specialised in planning and
managing major construction and
infrastructure projects. The Paul
Wurth Group operates more than 20
subsidiaries in the main steelmaking
regions of the world.
