THE WELDING OF REINFORCING STEEL

A review of literature relating to welding of reinforcing steel has revealed that experimental work was necessary, using local materials and construction methods to examine joint efficiencies for both butt and fillet welded cold twisted structural grade rebars. The minimum fillet weld length required to develop the full strength of the rebar has been determined while the effect of electrode type on the throat thickness has also been studied. In addition the optimum welding conditions for the fillet welding of rebar have been established. The butt welding of both grades of rebar has shown that there is no reduction in joint efficiency with either cold twisted grade 410C or structural grade 230s rebar provided that proper procedures are used. However, mma butt welds in rebar take an increase of an order of magnitude in time compared with fillet welds. If butt welds are welded in the fastest possible manner with resulting slag inclusions, the joint efficiency falls by only three percent (A). (TRRL)
