摘要： A method of detecting dust includes: a first step of monitoring a resistance value welding and determining if a variation amount of the resistance value per unit time is equal to or more than a first threshold; a second step of monitoring the resistance value after the first step and determining if a variation amount of this resistance value per unit time is equal to or less than a second threshold; a third step of determining if a difference value between a resistance value for calculating the variation amount equal to or more than the first threshold and a resistance value for calculating the variation amount determined equal to or less than the second threshold is equal to or more than a third threshold; and a fourth step of determining that dust is generated when the difference value is equal to or more than the third threshold.
