So here's my last multipass on armor plate with Fagersta 1.2 mm wire. If anyone has ever worked with that wire I'ld apreciate your input. I was working at 275 amps at around 9.9mpm.
Hitch, did you pre and post bend heat treat the armox? What application were you using it for?
I've got 440T as my drop arm guard on my off-roader
Edit: I get some see a lot of armour when it's been used for its intended purpose. It's almost always the weld which fails, usually lack of penetration
No problems with cracking.... always careful to deburr edges well to prevent that happening.
I imagine you would get cracking if you used the wrong tooling combinations....
