6" poles WELD OR NO WELD? [RE-wrenches]

[Tom Simko]

 Rebar shouldn't be welded, you'll never see it done on
commercial/industrial construction sites. I believe the rule of thumb is 18
times the diameter for overlapping pieces in a pour (just tie wired). When I
need to scab on to a pipe to give it some purchase in a pier I go to the
scrap pile, anything welded on, or sticking out through a gas torch blown
hole will do, I like short pieces of angle iron, or 1" and up pipe. Anything
meaning scrap of suitable thickness and strength, but it sure doesn't have
to be rebar.
