Mig welding cast iron

By Weldfab Date 01-12-2006 19:08

Hello all. I'm new to the forum. I have been a welder/fabricator for 15 years now. I have a potential job coming thru my shop that will require me to make a cosmetic weld on some cast iron fittings. I have done a few samples with an ENI55 welding electrode. The results were acceptable but the time to perform the job was a bit too long. I understand that there is an equivalent of the afore mentioned rod available as a mig welding wire. Is this true? If so what kind of shielding gas would I need to use? Thanks to all for their time in responding and willingness to help.

Can you tell us what size the fittings are, the type of cast iron and the application of the fittings (are you working to a particular code or spec)?

The material is A 126 cast iron (or so I'm told) I do not know the application. Most likely for a pumps and of a more than 8 to 10 inch size. Thanks everybody for the help thus far. I'd love to get a few more options to help gauge range of costs.

INCO Alloys makes a NI-ROD FC55 cored wire. 50% Nickle.
Kinda big diameter though..( 50 pound spools available in 0.078" and 0.093" dia.)
FYI-
They also make a smaller diameter wire, at 93% Nickle (GMAW) .035" dia. and bigger. AWS 5.14, ERNi-1
