The two key imperatives of this process are that the weld
maintains the correct mechanical alignment of the pins and
that it does not produce any defect (inclusions). The alignment of the pins is important because the exact shape of
the winding directly affects the efficiency of…

…is
exactly the opposite. This allows the CO laser
light to penetrate through the PET and deposit
most of its heat at the PE/PE interface (see
Figure 4) where melting is desired. The result
is that the CO laser produces a mechanically
