ABSTRACT:
A control apparatus for resistance welding includes a time measuring device for measuring an energization time of a welding current, the energization time being required by a given electrode displacement during welding between an electrical conductive weld member and a member to be welded which are arranged between two electrodes. A time difference calculating device is operative for calculating a time difference between the energization time measured by the time measuring device and a preset target energization time. A feedback control device is operative for correctively increasing and decreasing a welding current, which occurs at a next weld timing, on the basis of the time difference calculated by the time difference calculating device.
