Abstract
An apparatus for controlling the resistance welding comprises a first operation for yielding an estimated condition value representing a state of nugget formation through the application of a thermal conduction simulation to welding part, a second operation for outputting a modification to welding condition based on the result of comparison between the estimated condition value and a predetermined standard condition value for forming a desired nugget, and an output for practically changing the welding condition of welding unit in accordance with the modification. Namely, the welding condition is kept controlled through the feedback of difference between a given standard condition value and an estimated condition value derived from simulation.
