Weldments metal braising and rotating derived sketches

Hi

I had two quick questions. I am messing arround with the weldments feature. I know they have stuff for weld beading but I was wondering what would be the best way to simulate metal brazing.

Second question, is it possible to rotate or scale a derived sketch. When I insert it all my options are grayed out. Is there away to link sketches while not having the exact same orientations.

Thanks in Advance
