Wrought Iron is good for forging and forges really good --- the reason that its so sought after ,
but it has a window that you can work to hot crumbles to cold splits but when you learn the stuff you will use it a lot when hot move slowly when it becomes bouncy on the anvil reheat--- heat to a red not yellow it will stay together
to weld bring up slow and to a faint yellow with borax bubbling and tap do not hit it hard it will crumble == welds great btw just takes time to find that sweet spot
when etched it looks like Damascus due to silica's in the iron its very tuff reason wheels were made from it very wear resistant for cost of use .most all parts of old wagons was made of iron most of those being wrought --
old bridges a good place to get iron also RR bridges were built long ago, and while your cutting out parts for guards or welded Damascus don't for get to get a section of RR track for your buddys that need anvils
and its best to harvest your wrought iron in the darkness of night wearing dark clothing and borrow a frinds car or truck .
and in doing so you will be able to tell your customer the history of the steel and you your self will know its origin. seam very important these days

in telling this I m not responsible for your safety nor you jail term nor am I recommending this method .but the dewalt 3000 volt portable saw would be a excellent choice
