got a question for someone looking to repair worn surfaces on some large (some are 3 feet wide and 4 feet tall, over 1000#) cast iron and cast steel parts with 420ss, which will then be ground. Also, coating with 316 and 304 ss which will be machined.
Which process would be more economical due the large surface area, flame or twin wire arc?
Overall, would twin arc wire be a better choice?
Any comments, suggestions, etc are welcomed.
I have seen 420ss 1/8"wire going for $2.00/# recently, which is pretty good.
