Welding to Old Rebar
Welding to Old Rebar
(OP)
I have a retrofit project that requieres removal and replacement of existing corroded rebar with substantial section loss. I anticipate welding new bars to old once sound material in the existing is encountered. However, I am concerned with the weldablity of A305 billet steel rebar from the early 1960's. Is anyone aware weldablity issues to steel of this type from this time period.

Usually, we extend the new bar alongside the old, spliced along good quality lengths of the old bar. Or a mechanical splice would possibly be appropriate....but welding - I wouldn't do it.

It would be highly unusual to weld rebar together during a retrofit or repair project.
