Welder package
Siemens VAI supplies a range of welders
to handle the though requirements of
coupled pickling tandem mills and
continuous tandem cold mills:
LW21H: Laser welder capable of
processing grades up to 1,300 MPa with
no weld over thickness, with welding
flexibility over a large grade range.
FB21C: The flash-butt technology has
been very successful and is widespread
around the world. Our SIROLL CIS
Weldamatic® process ensures the best
results and high flexibility with respect to
new grades.
FB21S: This flash-butt welder with
integrated shear delivers perfect weld
geometry and minimization of the strip
break rate. DC current ensures very
smooth flashing and the possibility for
pre- and post-weld heating. Oxygen-free
and adapted weld confinement
guarantee good welding of high strength
and high carbon steel grades.
In-house manufacturing and testing
Key components of our mechatronic
packages and other core equipment for
our mills are manufactured and tested in
the Siemens VAI workshop at Montbrison,
France.
