摘要： While steel sheets are positioned and held by a holding mechanism, a first laser beam is applied to a heating region of the steel sheet to space the steel sheet from the other steel sheet by a predetermined distance. A second laser beam is applied to a welding region to weld the steel sheets. An amount of heat applied by the first laser beam, a moving speed of the first laser beam, and a focused spot diameter of the first laser beam are set to keep the sheet irradiated with the first laser beam in an unmelted state and plastically deform the sheet.

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.
