Evaluation of calculated arc energy heat input in MMAW processes
WebTable 2 contains a list of the welding parameters. Heat input values were calculated using the formula: heat input = (V × I)/S kJ/mm, where V is the voltage used, in volts, I is the current used, in amperes, and S is the weld travel speed (mm/s), for all the weldments. WebHeat input was calculated according to equation 1: (1) where, H= heat input in KJ/mm, η= efficiency = 0.75 for SMAW, V= voltage in volts, I= current in amperes, ν= welding speed in mm/sec. So in accordance with this fundamental fact three different heat input combinations corresponding to different welding currents i.e. 75 A (low heat input), drycleaners wellington cbd
