Ultrasonic inspection of as-cast products

What is the best wavemode, frequency, sensor diameter to look for longitudinal cracks and shroud porosity on as-cast products such as slabs and billets from a steel mill? we are trying to inspect a 150mm square billet but cannot see the backwall reflection (there seems to be a lot of scattering). Any ideas?

DEAR FRIEND,
I THINK FOR YOUR TEST CONDITION,NORMAL PROBE WITH OVER 24mm.Dia.(LONGITUDINAL WAVE),0.25-1 MHZ FREQUENCY IS
WELL.YOU CAN ON-REGECT SWITCH FOR OMITTED OR DECREASE NOISE ON DISPLAY(CRT/LCD).HIGH DAMP PROBE MAY HELP YOU
FOR PREVENT OF NOISE EFFECTS.

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.

mances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
