German Weld Symbols

[karinmk]

I am trying to help a fabrictor deicpher a german fabrication drawing, circa 1999. It a platform for a steel induction furnace, sheet metal/ tube steel. I can't determine what is meant on some of the weld symbols. Does anyone have expereience with European weld symbols, or know where I could look? An example, what appears to be square groove weld symbol followed by nx/100/200/ and f. Pos. 9+10 noted below.

Web search so far not turning up anything of value.
