Thanks for the replies guys
....I was being a bit
facetious in asking about this. I have been in this business of structural steel/welding for 34 years now and have never heard of an AWS CWI Level I, II, or III and was pretty sure that nothing of the sort even existed, but this guy was convinced he was right and who was I to argue. He made a copy of my wallets cards and I just chuckled under my breath and went my way. I asked him was he sure it wasn't an NDT/NDE certification that he was thinking about and he was sure it wasn't. I feel like he had heard of guys holding some sort of NDT Level I, II, or III (ASNT) and he just didn't know enough about it to tell the difference.
Brent, I hold the ASNT VT II also, just because I took the small printed eye test and had the CWI already. It was just a matter of sending them money and they sent me a VT II card.
