I am thinking of using rebar for a project. Some stout shelving using 5/8"
rebar.
Can rebar be welded reliabley?
What rod would work best?

"Consumer Grade" Rebar is a total crapshoot as to it's composition and
weldability - it's literally melted down scrap that only has to meet
real loose specs, and often has half-melted ball bearings and bits of
carbide and stellite from valve seats and busted up scrap cars...

Get new small round bar or angle iron to weld up your shelves, and
you'll have a chance of making something that can last.

You can get Good Rebar that holds to the same metal composition
guarantees as bar stock and will weld nicely, but you'll pay as much
if not more for it than new bar stock. If you really don't need the
formed in bumps to hold the concrete, just get the plain bar stock.
