Welding Corten steel

[BensPlasmaAu]

Simple question. Is it standard mild steel wire and gas that is used to weld Corten?

Call your welding supplier, we did a large Cor-Ten job and bought Cor-Ten welding wire, It will keep the Cor-Ten characteristics in the weld joint. I'll post pics when I locate them....... It was industrial swings that were specked out by the customer...SERIOUS DESIGN OVERKILL

Found it, Like I said, serious overkill, these should last a generation or two...!!!!!!

As I understand, as long as you are doing a single weld root pass the steel should combine and mirror the characteristics of the corten.
I have welded dozens of things to Corten with straight mig wire and no issues.

That may very well be the case, you can certainly use standard MIG wire with no issues or minimal effect in many applications. In this particular case, the dwg had an engineers stamp on it and required certs.....what they want they get....lol I'm not interested in grinding out welds.....

Thank you all. I will save some cash and just go with standard and see how it goes. Otherwise, a quick wire change isn’t too hard.
