NDT for weldings and brazings

Which of the NDT technologies should one consider for detecting flaws (i.e., pores, cracks, debonding) in weldings and brazings?

HI George,

With the limited information you are providing, it is difficult to provide an answer that will meet your specific situation. You don't specify a code, where is this testing should take place, part geometry and thickness, etc... Inspecting weld for pores and crack may be easely done with radiography, but it will not find disbond. If the surface is smooth, maybe UT with a Bondtester would be your answer. Those are my suggestions with the info you have provided.

Cheerios,

Michel

Hi Michel:

Thank you so much for this response as well as for the previous one. They are linked and as such, I believe you have answered my question. My "weld" was the thin coating from the previous message where you suggested exploring the eddy current route.


Take care,
George

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.
