The welding procedure for reinforcing bars used in reinforced concrete takes place at fixed\nindustrial installations. The welders must ensure that the reinforcing bar positions are maintained\nthroughout all stages leading up to concreting. Fusion welding offers an alternative procedure that\nentails fewer risks for the workersâ?? health. In this study, we aimed to determine the minimum\nparameters for the intensity, pressure, and time necessary to ensure the level of performance required\nby this assembly welding. A total of 2160 joints were manufactured, comprising the different\nthicknesses. For each thickness measurement, 45 different combinations of parameters were applied.\nThe joints were evaluated based on the resulting dimensions and on the failure force necessary to break\nthe joint. For different thicknesses, the breaking loads were over 7350 N. In addition, the welding\ncycle times did not exceed three seconds. Based on the results obtained in this study, we concluded\nthat assembling rebar (manufacturing reinforcing bars) by electrical resistance welding is a viable\noption. This method is fast, safe, and clean, and reduces the risks to the workersâ?? health.
