Myself (and many colleagues) are professional EE's. We all own soldering irons and know how to solder in the most basic sense (I'm one of the few with a hot-air rework station and a stereo microscope).
About half of the professional ME's I know either own a TIG/MIG welding system and/or know how to weld.
