Hi,
I wonder if someone can help.
It's well documented about the potential for exposure to chromium oxide, irritating gases etc when welding stainless steel but my question is "what substances would it be reasonable to expect a welder to be exposed to from welding non-stainless steel surfaces?"
NB - I'm excluding from my question the materials that may be present as contamination from the process the piece of equipment is used for.
Thanks all

Puds, the main constituents will be the welding rod as fume, carbon monoxide, carbon dioxide, ozone, oxides of iron and any trace metals and other elements that may have been added to the steel or other metal by the foundry. As you say there may also be surface coatings (possibly lead paint) to form part of the welding plume. Still nasty stuff that is routinely breathed by welders and also subject to skin absorption.
Many of these constituents have their own WELs.

My answer would be none, it wouldn’t be reasonable to allow a welder to be exposed to welding fumes for long or short periods of time. Whatever you are welding fumes generated from welding are carbon monoxide, carbon dioxide, inert gases, oxides or welding aluminum traces of beryllium; I would recommend a portable LEV System to remove air contaminants from the welder's breathing area. Or other option air ventilation built inside welder shield. Thus reducing exposure.
