  • fluxcore vs spray mig

    if cost wasn't an issue(gas, wire, ect) which process would you rather use? We've been throwing around the idea of using spray solid wire instead of fluxcore for our big steel projects and I am just trying to see what other people think. We mostly use 3/8 x 3 angle and 1/4+ square tubing of various sizes. Here's a pic of a drive frame that I make every three weeks or so.

    The deposition rate with spray wleding is twice that of flux-core. Penetration is excellent, there is absolutely no spatter, and no clean-up is needed.

    I think you'll decrease your production time significantly with spray.

      That being said anything out of position will require pulse as the puddle is so fluid it will fall right out of the weld joint like melted butter.

        If that piece isn't being made to a code, such as AWS D1.1, and you can position it, I would go for it.

          What about a duel shield?

            That's not true.
            The large flux core wires will way out deposit solid wire on flat work and the large increase in penetration allows for smaller fillets as the effective throat is so much larger. Look at the specs on .120 NS3M wire at 600 amps.

            Out of position it's not even a contest, flux core deposits way more and the dual shield wires are the absolute king of out of position deposition rates.

            That's why Caterpillar and similar companies burn so much flux core in spite of the smoke and flux.
