摘要：A method of generating a real time control signal for use in an electric arc welding process having welding voltage and welding current, said method comprising: measuring the welding voltage and welding current at a first time, momentarily changing either the welding voltage or welding current by less than about 10%, then measuring the welding voltage and the welding current after the change at a second time, determining the welding voltage difference between the first time and the second time, determining the welding current difference between the first time and the second time, producing a derivative value representing the desired control signal by dividing the welding voltage difference between the first and second times by the welding current difference between the first and second times and generating the control signal by the derivative value.
