The ultrasonic inspection system has been completely
tested at laboratory level. Laboratory tests have proved
that the pulse echo ultrasonic technology is a suitable
method to be used for non-destructive testing in the
powder metallurgy industry. Results show that a clear
visual representation of the defect can be produced
using this technology which can be used to determine
the size and the location of the faults. Therefore, this
technology cannot only be used as a monitoring/inspec-
tion tool but also as a quality assurance tool. In addition,
it can be used to help die design and parameters
improvement.
