Welding Wrought Iron (not Cast Iron) to Carbon Steel
Welding Wrought Iron (not Cast Iron) to Carbon Steel
(OP)
Has anyone ever developed a welding procedure for welding wrought iron piping either to other wrought iron piping or common carbon steel piping. Note: I am not trying to weld cast iron! My application is working in a very old piping system that made use of wrought iron piping nearly 50 years ago. I am now attempting to add to and maintain the system. Annecdotal evidence with "old time" welders is that they used standard oxy-acetylene stick welding without any problems except getting the pre-heat just right. Wrought iron is a very malleable material - almost malleable to a fault in a piping system.
Also, since the material specifications for wrought iron piping seem to have been rescinded by most standards organizations decades ago does anyone have any copies of those old standards?
Thanks in advance. Kind of an obscure topic.

alloy SAE 4130 or 4340. Oxy-acetylene welding
will also work, but you are heating a larger
area.

This stuff is so versatile I'm surprised it isn't more popular.

and i am expected to weld cast iron to mild steel by mig welding, I am at the moment finding it very difficult.
could you please advise if this is possible.
Many thanks Don.
