Rant: Cleveland boiler shop says stick welding is dead for new builds, I disagree
I was over at Ohio Structural in Cleveland last Friday picking up some steel and their foreman told me they haven't hired a stick welder in 3 years. They run mig and flux core on everything now. He says it's faster and cheaper. But I see way more porosity in their stuff than what we get with 7018. Am I old school or is there still a place for stick on big pressure vessels?

Man, is porosity really that big of a deal though? I see plenty of clean mig and flux core jobs that hold pressure fine if you dial in the settings right. Maybe we're overthinking it for most shop work.

Read a report from Lincoln Electric that said stick still beats mig on heavy wall vessels where penetration matters. Cleveland shops are chasing speed but that porosity is real.
