EB welding of F-14 (May Welding Journal)

I recently read the article in the May issue of Welding Journal on EB Welding the F-14. Absolutely fascinating! The article described a procedure where areas of possible defects were drilled out and an interference fit "Multiphase 35" pin installed. While I am familiar with what an interference fit is, what does this pin look like ? What is it made of? I am no engineer, and a barely adequate weldor, but I am always wanting to know more about the world. Anybody out there who can shed some light on this?

I read a similar article on this (draggbody and I are friends) while researching this, the pin he is referring to is basically a machined rod with a threaded end for a castle nut, on this pin, you install the rotor with the bearings inside. Hope that clears up a little bit. It looks like he's using a migwelder, his welding looks good and solid, its just a question as far as the science behind welding these two metals together and the safety issue it creates.
