To determine the correct welding current as function of the geometrical condition of groove incorporating deviations from prescribed standard groove shape, a quantity termed "joint capacity" was introduced, using which, linear expressions have been established relating the groove geometry to welding current and speed. The empirical relation thus derived gave results agreeing well with the expression given by A.A. Wells relating total heat input to quantity of electrode melting. These simple linear expressions enable active control of welding parameters for maintaining uniform reverse bead in automated welding process which produce defect free weld.
