A file-size of 28.5MB means I cannot put on-line here the whole final document from my research work on hydrogen movement in the weld zone of constructional / structural steels.
A smaller PDF document summarises with pictures the experimental techniques I used and the steels I experimented upon. It's 3MB size, so here is a direct link to it, Hmov_research.pdf. The images can be meaningfully magnified by four to eight times in the PDF viewer if you are interested in greater detail.
