eseemann Posted October 27, 2015 Share Posted October 27, 2015 Good Morning All, Can a black iron pipe be joined to mild steel either with O/A welding, brazing or stick arc welding? thanks Quote Link to comment Share on other sites More sharing options...
DSW Posted October 27, 2015 Share Posted October 27, 2015 Usually. Most pipe itself is steel even if people refer to it as "iron", Fittings are another matter. Most fittings are steel as well, though I have run across a few that were cast, often imports. I have often mig and arc welded 1/2" to 2" black pipe. You can braze cast iron as well as steel though. In fact brazing is often the go to method of doing cast repairs. It is possible to gas and arc weld iron, but results are spotty. Quote Link to comment Share on other sites More sharing options...
