(OP)
I have a client who has non-specific concerns about potential for EMI from electric welding of building structural elements in proximity to operating data processing equipment. Does anyone know of any standards pertaining EMI mitigation for electric welding?

If he can't give you field strength levels that you have to stay below, there really isn't much you can do is there?
This IEEE paper might be a starting point for you:

Avoid high frequency TIG welding. Route welding cables away from electronic equipment and cabling. Connect the work cable to the work piece as close as possible to the area being welded. Route the electrode and work cables together and secure together with tape if possible.
That may have to be good enough.

Also we use the building steel for the welding grounds as all welding machines are in auxiliary buildings. We snake the hot leads in and around all the process transmitters.
