Welding on rebar is not the preferred method of construction, as it may
weaken the steel. Before I knew better, I tried this once and the welds
didn't hold well (and they were -- in theory anyway -- done by a
professional). Not saying it can't be done, but there are many who argue
against welding.

Subject: Re: [TowerTalk] Rebar Cage Question
OK now we are getting to the question I have been wanting to ask. Can a
rebar cage work just as well if it is cut and welded together rather than
bent and wire tied? It is my plan but thought I might toss the idea out for
the critics.
