A resistance welding apparatus is provided with: a pair of electrode chips; a power supply device for supplying the electrode chips a welding current; and a spattering detecting device that detects a spattering. The power supply device supplies to the electrode chips a preset welding current until the spattering is detected. The power supply device supplies a current on which an additional current is added to the preset welding current, after the spattering is detected, until a preset energizing time expires.
