About this detail

Standard welded reinforcing bar connections comprise flare V-groove, single V-groove with split pipe backing, flare bevel groove, complete joint penetration groove, and double bevel groove welds. Weld root preparation requires chipping or grinding to sound metal before welding the second side, with a one-eighth-inch maximum root opening. Electrodes must be low hydrogen type E90XX for A615 reinforcing or E80XX for A705 reinforcing conforming to AWS D1.4, and all welded reinforcing bars must conform to ASTM A706 subject to continuous inspection. A weld schedule prescribes minimum weld lengths ranging from three inches for bar size number three up to six inches for bar size number ten.
