Typical Reinforcing Bar Weld Splices

About this detail

Standard groove weld configurations provide direct butt splices in reinforcing bars. Single-V-groove, double-V-groove, single-V-groove with split pipe backing, single-bevel-groove, and double-bevel-groove welds accommodate both horizontal and vertical rebar positions. Root openings maintain a one-eighth inch spacing with bevel angles ranging from forty-five to sixty degrees. Chipping or grinding to sound metal occurs before welding the second side, using low-hydrogen rods, and applying preheat as required. Applicability depends on bar size, utilizing details A, B, and E for bars number nine and larger, and detail C for bars smaller than number nine.
