UT for disbonding

we have the task to test for disbonding of SS 1.4550 using SAS4IG (nearly similar material) as weld metal. The thickness of weld metal is appr. 3 mm. Testing should be performed using SDH as reflectors. the test block has a diameter of 273 mm (not ready yet). The test object is ready next Monday.
I prepared a MSEB4, E series, to be adapted at the curvature of 273 mm.
But now I am not sure if it is the right probe. Should`nt I use higher frequencies?
For any hints or advices I thank You in advance

The best probes for disbonding detection are the benchjmark and between 10-15 MHz because you you need haigh resolution for diferentiate the metal base and the SS interface

I have to verify disbonding using ASME IV Technique two.The customer haven't gave me the standard of acceptance yet.Which could be an acceptance standard for ASME?
Thank you in advance


Product Spotlight

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.
