What? Where? All the welding jobs I have ever known were terrible for your body. Between the exposure to high UV, all the bits of toxic crap that you are breathing/ingesting, and the noise from heavy machinery, it's quite bad. And that's not to mention just the baseline damage from lugging and hauling and hefting heavy pieces of metal.
My grandfather did welding for Bethlehem Steel as did my father. My grandfather died from a weird cancer from all the crap he was exposed to. My father quit working at the mill precisely because it was doing so much damage just by wear and tear. They both made a point to make sure that my job would be based around my brain and not my body.
Electricians, by contrast, at least don't have anywhere near the same level of exposure to toxic crap.
