Ok we're welding some Armox 500T plate. We were using Hardox 500 plate with an 80k tensile wire. This new armox plate requires preheat if we keep using a ferretic consumable. If we go to an austenetic consumable we can weld it at room temperature. The stainless wire they recomend is an AWS A/SFA 5.4-92 E307-15 or a AWS A 5.22 E307 LT-2.
My question is can you cross reference this wire with another more common A 5.22 T series wire like aN E308 or E309LT1-1. Esab makes an E307TO-03 and an E308TO-03 for welding armor plate, but i don't know how hard it would be to get and i need some wire fast like everything else ya know.;-) Second question is i haven't seen a wire discription like this meaning no # after the T and would using a 307TO-03 really be any different then using the wire they stated on the armox website (E307 LT-2)?
Thanks, Kix
