dickb Posted November 14, 2009 Share Posted November 14, 2009 I've collected a few pieces of old wrought iron and would liketo try forge welding them. There's a small amount of rust on them as they have been sitting out inthe open for years. Do I need to do anything more than wire brush off the loose rust before welding welding. ? Thanks Quote Link to comment Share on other sites More sharing options...

nonjic Posted November 15, 2009 Share Posted November 15, 2009 you just need to get it hot, very hot! it should self flux, but a bit of borax wont hurt. you can wire brush the iron to get the flakey off the outside. There is a chance the corrosion has got "into" the iron (its a very fiberous structure) in which case it will probably crumble under the hammer! have fun, its a lovely material to forge.

KYBOY Posted November 16, 2009 Share Posted November 16, 2009 Iron welds at a lot higher temps than normal knife steel. White hot, nearly sparkling hot. Makes nice hawks and knives with high carbon bits welded in. Quote Link to comment Share on other sites More sharing options...
Guest mod07 Posted November 16, 2009 Share Posted November 16, 2009 I will relocate this to another section, as this is not blade related Quote Link to comment Share on other sites More sharing options...
