Welding Rebar
(OP)
Is there any way to weld grade 60 rebar? A contractor has cut the rebar over a column in a two way slab system. The owner wanted to put in a recess shower stall and the contractor chipped out the concrete and cut out the rebar. Then they decided they should check with an engineer. We considered using connectors to splice rebar, but there just isn't enough room since the rebar are spaced very close together and the connectors conflict with the perpendicuar bars.

2) The device Dancristescu is referring to is the Lenton Terminator.

You can get mechanical splices that do not require threaded ends.
Lenton does these for smaller bars up to #6.

You just need to have the existing bars projecting 6" past the concrete face (or cut away the concrete around it that distance).
I imagine these would be cheaper and easier to do on site than welds that may need to be pre-heated and inspected.
