摘要： The intensity of first reflected ultrasonic waves reflected from an end of a first electrode tip is measured while the electrode tip is separated from a workpiece. The intensity of second reflected waves reflected from the end of the electrode tip is measured while the electrode tip contacts with the workpiece. Based on the above intensities, an intensity ratio (reflectance) and the fraction of the waves entering the workpiece are determined from the following equations: reflectance=(intensity of second reflected waves)/(intensity of first reflected waves) fraction of waves entering the workpiece=1−reflectance. From a predetermined correlative relationship between a contact area of a region enabling ultrasonic waves to be incident on the workpiece and the determined fraction of the entering waves, a ratio (contact area ratio) is determined between a total area of the region and a contact area of the region contacting with the workpiece.

摘要： A spot welding inspecting apparatus is provided with: a gun chip; a signal transmitting part; an ultrasonic sensor; an inner cylinder; a through hole; a partitioning cylinder; a first flow path; a second flow path; and a third flow path.The inner cylinder is inserted to an outer cylinder of spot welding gun and holds the ultrasonic sensor. The through hole is provided on the inner cylinder. The partitioning cylinder surrounds the through hole and is inserted into a gap between the ultrasonic sensor and the outer cylinder. The first flow path is formed between the inner cylinder and the partitioning cylinder by passing the through hole from an inner portion of the inner cylinder. The second flow path is formed at the gun chip to be circulated around a front end of the partitioning cylinder. The third flow path is formed between the outer cylinder and the partitioning cylinder. A cooling agent flows in an order of the first flow path, the second flow path and the third flow path.

摘要： The heat generated by a laser oscillator is partly radiated toward a frame. The radiated heat is partly absorbed by a cooling mechanism. The remaining heat is transferred through a chamber which dissipates part of the heat, to a heat insulating panel, which blocks most of the heat. The heat generated by the laser oscillator is partly radiated outwardly and reflected by a casing inwardly toward the frame. The reflected heat is partly absorbed by cooling mechanisms. The remaining heat is transferred through chambers which dissipate part of the heat, to the heat insulating panel, which blocks most of the heat. Therefore, any temperature rise of the frame due to the heat generated by the laser oscillator is very small, and the frame is prevented from being deformed due to the heat from the laser oscillator. Because the frame is not deformed, a laser beam emitted from the laser oscillator is applied to a desired position which remains unchanged.
