Metal built up detection
Metal built up detection
(OP)
How to detect a material like fitting that has been built up by welding? Such as fitting reconditions that adding with filler metal weld then grinding to get smooth surface. Does some chemicals can detect them? Which chemicals? How to used/perform those? Or any method else?

I would start with X-ray, look for internal defects.
You could also acid etch the part looking for surface changes.
Maybe even something like Mag-particle testing to try and reveal differences in material.

But it is hard to determine if that is what you are asking. Are you asking how to derermine what the material is or are you trying to determine if a repair has been made?

For forgings or other wrought product forms, weld repairs should be scrutinized.
