METHOD FOR CONVERTING WELDING CONDITION OF WELDING ROBOT

摘要

PURPOSE:To convert exactly the welding conditions of a welding robot by providing mechanisms for inputting smoothly the command inputted to a numerical control device to a digital/analog converter and converting a welding current value to a wire feed speed. CONSTITUTION:A memory 2 stored therein with the arithmetic operation sequence of the general equation for the given straight line from the value X at the point (Y=0) of the given straight line on the plane of which the X-axis is the input value of welding conditions and the Y-axis is the command value to a digital/analog converter 6 to apply a command to a welding machine 7 and the inclination of the given straight line is provided at a numerical control device 1 in a method for converting the welding conditions of a welding robot. The actual input value of the welding conditions to be inputted in the stage of a teaching operation for welding is once stored in the memory 3. The value of the Y-axis determined by substituting said value into the general equation is used as a command value to the converter 6. Such command value is outputted to the machine 7 and a welding torch 9 is moved on base metals 10, by which welding is executed.
