powerful 450 W fiber laser. It comes with a hand piece
with an integrated wire feed (wire thickness 0.6 mm) with
automatic feed, with which homogeneous welding can
be carried out. During the welding process, the welding
seam width can be adjusted manually. The hand piece
is attached to a 3.5 m long energy chain and weighs no
more than 1.5 kg. Thus, it is very easy to handle and fle-
xible to use.
The AL-ARM welding system is completed by a 3D visua-
lization. This is realized by means of (pass-through) 3D la-
ser protection goggles, which show the surrounding and
the welding task simultaneously. The welding area is en-
larged and the process-relevant data, e.g. the crosshair, is
superimposed.
Laser safety is of great importance: The integrated mate-
rial recognition allows the welding process only when the
hand piece is placed on the workpiece. This avoids direct
laser radiation being emitted uncontrolled. The built-in
laser safety circuit is approved by TüV Süd.
By using the laser system AL-ARM, laser welding of po-
res, ripples and offset seams can be carried out in a mo-
bile, fast and extremely flexible manner.
