In welding tailored blanks,
Laserline‘s diode lasers
prove themselves by their
high welding quality and
process stability.

Spot-in-spot modules improve
the seam quality and make
even more robust processes
during welding of aluminum in
the outer skin possible.

Changes in the distribution The spot-in-spot design was specifically
of maximal power in the developed for keyhole welding processes: A
exterior of the spot (left side)
towards maximal power bigger outer spot is overlaid by a smaller inner
inside (right side). spot, which takes over the actual keyhole welding
and which, if necessary, can be transferred in the
feed direction. By this, asymmetric seams are
perfectly controlled.

Due to this configuration, the advantages of
keyhole welding (high welding penetration depth
and process speed) can be combined with those
of heat conduction welding (smooth seam surface
and low spatter formation).
