Checking quality of weld seams.

[fagot]

Hi,

I am looking for a tool or instrument that lets you check the quality of weld seams. The simplest tool I have heard uses 2 magnets and some liquid which is poured on the seam to determine the quality of the weld seam. I am looking for the name of that tool/instrument and where can I buy this? If you know any other simple tools, please help me find it.

Thanks.

Interesting screen name....French I hope??? J/K

Anyway, you are looking for methods of NDT or Non Destructive Testing.

There are many available, the simplest is using 2 part Dye Penetrants. Another easy (though not cheap) way that you sort of described is called Magnafluxing which uses metal powder and electromagnets to show lines of stress and cracks.

You could also do ultrasound or x-ray

Is that pronounced "Fahgo"?
