Other than a ultra sound or destruction type just a visual is all there is.

X-RAY.
Usually one does a lot of welding, practice and destructive testing before doing something that matters.

Then if you had the machine set right and layed your bead as you did with the your test pieces then you should be ok.

What process and electrode did you use?

Are the welds even across the top and bottom leg?

Any porosity or undercut?

Are the welds rolled or do they have a "Ropey" look?

do a bend test, or just go pay the money at your nearest welding certification center to take your cert tests. Take tests for the same methods you weld with (eg. 1f, 2f, 3f, 4f, 1g, 2g, 3g, 4g, etc... and with the welding process you are using). If you pass the tests, then great...if you don't pass...well...

After 14 years welding in heavy steel fab I'm of the opinion that having certifications from whatever local welding instruction facility is absolutely no indication or garentee whatsoever as to that persons actual welding ability.

At the end of the day welding is like riding a bicycle. You can read about it and be taught the physics behind it but the only way to get good at it is to ride it.

Didn't say it was an absolute indication...however, if a cross section test shows no occlusions, the bend test doesn't break it and the instructor doesn't fail it for just looking like crap, having undercut, lacking penetration, etc... it's probably a good start for him to tell if his welds are decent. If you're doing welds that require full x-ray analysis or food quality stainless, then get your certs (cause they most likely won't hire you without them) and then make damn sure your welds will pass all of the x-ray tests everytime you make one...and have your insurance paid up just in case one fails.
