I am going to answer myself since someone might care in
the archives. I talked with a welding inspector today and he said
that all the welders want to use E6022 for welding deck because its cellulose
flux boils out the galvanization and paint. He said this is a
bigger deal for steel joists and that E7018 should weld easier on
structural steel. He also said all the welders are qualified to weld metal
deck with E6022.
I also called an engineer who said they
specifically changed their general notes to read use E60XX non low hydrogen
electrodes for welding metal deck because E70 low hydrogen always melts through
and they had a problem on a job with it.
If you weld A36 plate to A992 you are still supposed to
use E70XX low hydrogen electrodes right? Then why not when you weld metal
deck to A992?
I am dealing with a
question over what type of electrodes are required for puddle welding metal deck
to structural steel. The contractor wants to use E6022 electrodes and
the plans say they are supposed to use low hydrogen
I talked with a deck
supplier who said the most of deck is 38 ksi - ASTM A653 and he said he knows
that he talked with local erectors who said they use E6022 electrodes. I
had a note in book from a class I took 4 years ago that said everyone wants to
use E6022 for steel deck but they should be using low hydrogen
What does AWSD1.3
require low hydrogen electrodes for welding metal deck to A992 steel
members? If low hydrogen electrodes are required why do people want to use
