Hi NDT III/LarryL and Jwright650,
I agree with you all, if we combine all post and to summarize that as below:
Its not required any other special set up or other things except for L-Wave probes and a Piece of materials which shall be UT tested. We need little bit more trail and practice, as well.
In addition that, there is another info that saying Weld cap should be grinded flush.!!
By the way not only this site fantastic, People here are fantastic, as well. Even you do not know him/her and you share what you have known about welding, NDT, Metalurgy, experience etc..
Thanks to All.. :)
