If they didn't spec what welding to use, I wouldn't worry too much about it, as it's not pressure pipe or a structural component. I would try to get away with a bevel weld and no root. What is hand rail designed to? point load and maybe an allowance for impact?
I would use mig or tig either way, since you'll be touching up any splatter, the welder will thank you too, since galv is already so crappy to work with.
I hope the project also specs how to touch up the galv coating, and the directions to the nearest hospital.
This is not how handrails are to be fabbed.
No, management frowns on double posting. Cross-posting, i.e. putting a thread in the other forum referencing this one (or vice versa) is actually encouraged.
