A good deal of information about weathering steel and its welding is
available at the Bethlehem Lukens Steel web site
<URL:>.  My web
site <URL:> has information on
the weathering of weathering steel. On receipt of a mailing address
I will be happy to send a pertinent paper, The Performance of
Weathering Steel in Sculpture.

As for contaminants, in my judgment the work would be more valid if
actual materials were used, rather than simulations.
