Welded Splices

In general, CRSI recommends against manual arc welding in the field. However, if necessary, field-welded splices are accomplished by electric arc welding the reinforcing bars together. Welding should conform to AWS D1.4/D1.4M, "Structural Welding Code - Reinforcing Steel" of the American Welding Society.

CRSI recommends against connecting crossbars by small arc welds, known as "tack welds." Tack welding is a factor associated with brittle failure of reinforcing bar assemblies.
