Figure 9. Numerical result of maximum temperature across the section (left figure) and along the
width at different depths (right curves), case with LSP (the horizontal high temperature band is
located in the composite with a peak at the interface).
The thermal field across the assembly section,
resulting from the numerical simulation, clearly
indicates that the copper protection over-heats
(Figure 8).
From this point, the academic partner IREENA
ran a new batch of simulations to improve the
inductor design and thermal requirements for the
tooling. They identified a specific set of process
parameters (among others speed, gap inductor/
composite part, cooling, power, a new inductor
design and some tool support upgrades to weld
without burning the LSP). This implementation
results in the temperature fields and measurements
in Figure 9 and Figure 10, which is a drastic
improvement compared to the previous results.
On the one hand, experimental implementation
of the modelling recommendations gives a
better thermal field, in which the LSP over-heat
disappears. On the other hand, temperature width
gradient increases. It reaches ±60°C in the welding
tests with LSP, while it was around ±25°C without
LSP.
RESULTS - A WELD WITH LSP
The typical assembly results presented hereafter
(Figures 11 and 12) are for pultruded stringers on
19-ply skins with LSP. This section will analyse a
weld using visual and ultrasonic inspection, and
cross-sectional micrographs. The upper face of the
skin, on stringer side, is clean with no visual mark,
even close to the stringer free edge.
