Hi,Is there any body heard of Driffracto sight or D-sight for checking welded joints? Is there any place I can purchase this or I have to make it by myself?Thanks a lot for your comments.
Reply:I've never heard of it but here's one site that provides a starting point as to the insides and inner workings. http://www.ndt.net/article/ecndt98/aero/025/025.htmIt's got more long words than I want to deal with.
