low crystallinity of the final weld. A post process
anneal cycle is being explored as a manufacturing
possibility since parts can be annealed in bulk
using lower cost equipment. Prior to annealing, the
specimen was welded at the rate of 12.7 mm/s and
385°C. A preliminary annealing cycle was selected
for this study, which would need to be optimized
in the future.
Manufacturing Environment
The last weld parameters evaluated were the effects
of different manufacturing environments on the
final weld quality. Both specimens were welded at
12.7 mm/s and 385°C.
As a manufacturer it is important to verify
that drying affects the final part quality as it is
an extra processing step that requires time and
money. For this preliminary screening, drying
was compared to " ambient " panels that had been
exposed to immersion tank ultrasonic inspection,
wet wafer saw machining, and shop temperature
and humidity conditions. The panels were weighed
and then dried at 120°C for over 96 hrs. The dried
panels were welded within 1 hr after removal from
the drying oven.
In addition, a panel that was exposed to oily
fingerprints and dust contamination representative
of potential shop handling conditions was
welded. This is not meant to be a full study on
contamination, but to begin to understand the
sensitivity of an induction weld to contaminants
which are detrimental to adhesive bonding.
Quality Inspection
After all welds, the lap shear specimens were
visually inspected and measured for thickness.
They were then ultrasonically inspected using 5
MHz TTU, and the c-scan was collected. If the
specimen passed this inspection, a 2.25 MHz Pulse
Echo (PE) ultrasonic inspection was performed,
collecting the time-of-flight (TOF). Any area with
poor inspection results was not tested.
Machining
All panels that passed the quality inspection were
machined into single lap shear coupons using a wet
diamond wafer saw. The single lap joint coupon
design was based on ASTM D10026
. Coupons were
un-tabbed, 25.4 mm wide and 190 mm long with a
12.7 mm overlap welded joint.
