A fully automatic, ultrasonic instrument to measure texture and formability
parameters on metal sheet is described. Arrays of EMAT transducers are used to
transmit and receive S/sub o/ Lamb waves propagating at 0 degrees , 45 degrees ,
and 90 degrees with respect to the rolling direction. By analyzing the frequency
dependence of the phase of the received signals, the long wavelength limit of
the velocities is obtained. Included is a discussion of this algorithm, and
subsequent processing steps to predict the ODC's W/sub 400/, W/sub 420/, and
W/sub 440/. On steel, the prediction of drawability parameters r and Delta r
based on a correlation developed previously by Mould and Johnson is also
discussed. Results of blind field trials at facilities of three suppliers/users
of steel sheet for automotive applications and one supplier of aluminum sheet
for beverage can production are reported. The former confirmed the Mould-Johnson
correlation for low r material but indicated that refinements are needed for
modern steels with high r. The aluminum data suggest a correlation between W/sub
440/ and the degree of four-fold earing (37 refs.)

Modern materials such as composites are more and more used for aircraft and
space structures and in mechanical and automotive engineering. Therefore quality
control of these materials is of increasing importance. The high resolutioncomputer controlled ultrasonic testing technique in the frequency range of 1 to
100 MHz is able to inspect and to analyse even components with complex geometry.
This report gives the foundations and clearly presents the possibilities of
reports with A-, B-, C- and D-scans. For test pieces not only CFRP-specimens
with a thickness range of 2 to 24 mm and with artificially inserted defects were
used, but also the mechanical engineering devices (15 refs.)

Ultrasonic metal welding is a process that solves a number of manufacturing
problems, mainly those concerned with the bond quality of metals and intensive
labor costs. It is becoming increasingly popular for many manufacturing
industries, such as appliance, automotive, and electrical and electronics
industries. Ultrasonic metal welding is an advanced technical process for
combining nonferrous metals, stranded wires and many metal-alloys. It is a
cold-phase friction welding technique; there is no melting, no high-temperature
buildup. The surfaces being joined are subjected to high-frequency mechanical
oscillations while being scrubbed together under pressure. The molecules of the
surfaces begin to swirl and intermingle with one another, creating a firm and
lasting bond (0 refs.)

The automotive and machine-building industry requires direct testing of the
extension of depth of hardened surfaces in metallic workpieces. The result of
the surface hardening can be monitored by application of the ultrasonic
pulse-echo method. A concept of a flexible computer-controlled ultrasonic system
for on-line monitoring is described which enables the manufacturer to guarantee
the safety and wear resistance of mechanical components with hardened surface (5

A vortex meter for measuring the intake air-flow of automotive engines is
presented. Due to the ultrasonic vortex motion detection the meter is especially
suited for operation under severe conditions in cars. Modulated flow experiments
indicate the almost instantaneous time response of the vortex shedding.
Operation of the vortex meter on a standard 2 liter engine revealed problems due
to superposition of the pulsating cross-flows and due to synchronisation of the
vortex shedding with residual flow modulations. Cross-flow effects have been
eliminated by self-adjusting signal filtering. It is shown that the disturbing
synchronisation effect depends largely on the design of the bluff body and the
meter tube. A very sensitive method for testing vortex stability is described (0
refs.)

The particulate matter emitted during the combustion of liquid automotive
fuels in a non-engine system has, for the first time, been collected in a
specially constructed 2.5 m dilution tunnel. The combustion of 'diesel engine'
hydrocarbon fuel was carried out in a straight-flow quartz-lined stainless steel
flame burner and the exhaust was injected into the dilution tunnel where it was
diluted with ambient air. The solid material collected in this way complies with
the international definition of a particulate. The fuel was injected into the
combustion chamber via an ultrasonic atomiser, i.e. as fuel droplets with a very
narrow size distribution. An online catalytic detector was used to determine the
amount of carbon monoxide produced. The system described has the advantage over
the traditional method of combustion in an engine that studies can be made of
the effects of individual combustion parameters on the nature and amounts of
particulates and other pollutants formed (23 refs.)

Describes two automated ultrasonic techniques, both used to measure the degree
of graphite spheroidization of nodular iron castings, and one of which is also
used for internal defect inspection. Such castings are used in the automotive
field, often to replace parts previously forged or stamped. Because of the
particular duties these parts have to perform, and the heavy stresses they have
to undergo in service, 100% inspection of the whole production is required. The
ultrasonic techniques described use multi-channel devices without requiring
complicated multiplexing solutions (0 refs.)

Ultrasonic welding, which produces bimetallic as well as monometallic
junctions of integrity at temperatures below about one-half the absolute melting
value, is effectively used in electrical conductivity applications such as
making wire terminal connections, attaching armature coils to commutator bars,
and consolidating stranded copper and/or aluminium wire into solid sections. New
aluminum conductivity alloys exhibiting improved physical properties, coupled
with the economic lever existent in substituting aluminum for copper, have
triggered extensive efforts to utilize the ultrasonic welding process in
electrical equipment particularly for the automotive, appliance, and aircraft
industries. Harnesses and starting motors are discussed, and ultrasonic welding
data for such applications, including equipment size, power, operating
parameters, and product quality, are presented
