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
