I have a complete set of drawings (not photos) showing all kind of welds discontinuities and I can send them to you if you're interested. They're drawings, not photos, but are very clear in what they show. They're the graphic material I hand over to my students at Mackenzie Presbyterian University in Sao Paulo.
It's printed material, not electronic, so I only can send them to you by air mail. If you'd like to receive them tell me your mailing address. If you live in the UAE the envelope will take some 12 - 15 days to reach you; there's no direct flight between our two countries.
